Endoscopy exists because there are questions imaging cannot answer. A CT scan can show that something is there, but only an endoscope lets a clinician look directly at the mucosa, judge its color, texture and vascular pattern, and take tissue for a pathologist — and tissue is what turns a suspicion into a diagnosis. So endoscopy is indicated when a symptom points to a hollow organ or body cavity and the diagnosis depends on seeing or sampling it: bleeding of unknown source, dysphagia, unexplained pain, an abnormal screening result, a mass that must be characterized, or a cancer that must be staged. A second, equally large category of indications is therapeutic — the same scope that finds a bleeding ulcer can inject and clip it, and the same one that finds a polyp can remove it in the same visit. Finally, endoscopy is indicated for surveillance, following known disease such as Barrett esophagus, inflammatory bowel disease or treated bladder cancer over time, where the point is not a new diagnosis but catching change early.
The airway and the gut are the two natural passageways clinicians enter most often, and although the anatomy differs, the nursing care rhymes. Both bronchoscopy and upper endoscopy pass a scope through the pharynx, which means both require topical anesthesia that abolishes the gag reflex, both require the patient to be NPO beforehand, and both make the single most important post-procedure rule the same: nothing by mouth until the gag and swallow reflexes return. Lower endoscopy substitutes a bowel preparation for the NPO throat rules, and the quality of that prep determines the quality of the exam — a colon full of stool hides the polyps the test was ordered to find. Across all of them the nurse's intra-procedure job is moderate sedation monitoring: level of consciousness, respiratory rate and effort, oxygen saturation, cardiac rhythm and blood pressure, with suction, oxygen, airway equipment and reversal agents within arm's reach. And across all of them, the two complications to think about first afterward are perforation and bleeding.
Endoscopy stopped being purely diagnostic decades ago; most scopes now carry working channels, and the patient who goes in for a look often comes out having had a procedure. Operative endoscopy includes laparoscopic cholecystectomy and appendectomy, video-assisted thoracic surgery, hysteroscopic resection of fibroids, arthroscopic meniscal repair, and endoscopic sinus surgery — real surgery, performed through incisions small enough that patients underestimate what was done to them. Endourology is the urinary version: cystoscopy with tumor resection, ureteroscopy with laser stone fragmentation, stent placement and retrieval, and transurethral resection of the prostate, all done through the natural urinary passage without an incision. The nursing implication is that a small incision does not mean small risk — the patient still had anesthesia, still had an organ manipulated, and still needs the full post-surgical assessment for bleeding, perforation, infection and organ-specific injury. Teach patients this explicitly, because feeling well the same evening tempts them to ignore the warning signs you gave them.
Every endoscopic complication falls into a small number of patterns, and knowing the patterns is more useful than memorizing lists. First is perforation — the scope or an instrument makes a hole in a hollow organ, and the patient presents with severe, persistent, escalating pain, fever, tachycardia, and a rigid or distended abdomen or subcutaneous crepitus if it is the esophagus. Second is bleeding, most often after biopsy, polypectomy or resection, showing up as frank blood, hematemesis, melena, hematuria, falling hemoglobin, tachycardia and hypotension. Third is infection, from transient bacteremia to urosepsis, mediastinitis, septic arthritis, empyema or peritonitis — fever with chills after any endoscopy deserves attention, not reassurance. Fourth is the sedation and anesthesia group: respiratory depression, hypoxemia, aspiration, arrhythmias and hypotension. Finally there are procedure-specific hazards that do not generalize — pneumothorax after transbronchial biopsy, fluid overload with hyponatremia during hysteroscopy, gas embolism from insufflation, orbital or skull base injury in sinus surgery — and these are the ones a nurse must learn per procedure. Delayed presentation is the theme that ties them together: many of these appear hours to days after the patient goes home, so discharge teaching about warning signs is not a formality, it is the safety net.
An endoscopy generates two separate results at two different times, and patients need to understand both. The first is the visual report, written by the endoscopist immediately after the procedure — what was seen, what was done, what was removed or biopsied, and any immediate complication. The second is the pathology report on any tissue taken, which typically takes several days and is the result that actually establishes or excludes a diagnosis. Because the patient is usually still sedated when the endoscopist explains the visual findings, the information often does not stick, so written discharge instructions and results, plus a scheduled follow-up contact, are essential rather than optional. The nurse's role in reporting is to document the procedure, specimens and their exact sites, sedation and recovery, and to make certain that a critical or urgent finding reaches the ordering provider promptly and that the patient knows when, how and from whom she will receive the pathology result. A result that is never communicated is functionally a test that was never done.
Smooth, glistening white articular cartilage; intact menisci, ligaments and tendons; a thin, pale, non-inflamed synovial lining; clear joint fluid; no loose bodies, no fraying, no erosions.
Ordered when joint pain, locking, giving way, swelling or instability is not explained by exam and imaging. It answers questions like: is the meniscus torn, is the cruciate ligament ruptured, is there a cartilage defect, is there a loose body, is the synovium inflamed or infected. It is also therapeutic — the same setting allows meniscal repair or trimming, ligament reconstruction, debridement, synovial biopsy and washout of a septic joint.
A rigid fiberoptic scope about the diameter of a pencil is inserted through a small stab incision into the joint space. The joint is distended with sterile irrigating fluid (or occasionally gas) so the surfaces separate and can be seen, and the surgeon inspects the interior on a video monitor. One or two extra portals let instruments in for probing, cutting or repair.
Cellulitis, an open wound or any skin infection over the planned portal site, because the scope would carry organisms into the joint. Ankylosis or a joint too fibrosed to distend makes the study technically impossible. Known bacteremia and uncorrected coagulopathy are relative contraindications.
Septic arthritis is the feared complication — a joint infection destroys cartilage fast. Also hemarthrosis, thrombophlebitis and DVT (especially knee and hip), neurovascular injury from portal placement or tourniquet, compartment syndrome from extravasated irrigation fluid into the calf or forearm, synovial fistula, joint stiffness, instrument breakage inside the joint, and the usual anesthesia risks. Escalating pain with a tense, swollen, pale, pulseless or paresthetic limb after the procedure is a surgical emergency.
Dense intra-articular adhesions, active bleeding into the joint, or severe effusion can obscure the view. A joint that will not distend limits inspection, and small marginal lesions may still be missed.
Verify the signed surgical consent and that the correct joint and side are marked — wrong-site surgery is a real risk in orthopedics, so participate in the site marking and time-out. NPO after midnight or per anesthesia (commonly about 8 hours for solids, 2 hours for clear liquids) for general or spinal anesthesia. Screen for allergies including latex and local anesthetics, review anticoagulants and antiplatelets with the surgeon for holding instructions, and check CBC and coagulation studies. Remove jewelry from the limb, teach crutch use and the postoperative exercises in advance, and shave or clip only if ordered. Baseline neurovascular assessment of the limb — pulses, color, temperature, sensation, movement — gives you something to compare against later.
The patient is positioned to open the target joint — supine with the knee flexed over the table edge or in a leg holder for knee scopes, beach-chair or lateral decubitus for shoulder scopes. A tourniquet may be applied to the extremity. Anesthesia may be general, spinal or local with sedation; if the patient is awake, the nurse coaches and reassures, since the pressure and irrigation are strange sensations. The circulating nurse maintains strict sterile technique, tracks irrigation fluid in and out, monitors tourniquet time, and documents specimens sent for culture or pathology.
Assess neurovascular status of the extremity distal to the joint every 15 minutes initially, then per protocol — pulse, capillary refill, color, warmth, sensation and motion. Keep the limb elevated and apply ice as ordered to limit swelling. Monitor the dressing for bleeding and drainage, and monitor vital signs and temperature. Report immediately: fever with a hot, red, exquisitely painful, swollen joint (septic arthritis), calf pain and swelling (DVT), pain out of proportion to the procedure with tightness, numbness or a tense compartment (compartment syndrome), or loss of a distal pulse. Teach the patient to avoid weight bearing beyond what the surgeon ordered, to keep the dressing clean and dry, and to call for fever, chills, worsening pain or spreading redness.
Findings identify meniscal tears, cruciate and collateral ligament injury, rotator cuff and labral tears, chondromalacia and degenerative cartilage loss, osteoarthritis, loose bodies, osteochondritis dissecans, synovitis from rheumatoid or crystal disease, and infection when synovium and fluid are cultured.
Never dismiss escalating pain after arthroscopy — pain out of proportion, or a hot swollen febrile joint, means compartment syndrome or septic arthritis until proven otherwise, and both are time-critical.
Pink, smooth tracheal and bronchial mucosa with visible cartilaginous rings, a sharp midline carina, patent airways without masses, and only a small amount of thin clear secretions. Cytology and cultures are negative for malignant cells and pathogens.
Ordered to see and sample the airways. It answers whether a lesion on chest imaging is cancer, what organism is causing a pneumonia that will not clear (especially in the immunocompromised), why the patient keeps hemoptysing, whether there is an aspirated foreign body, why an airway is obstructed or a lobe collapsed, and how far a tumor extends for staging. Therapeutically it is used to suction thick mucus plugs, remove foreign bodies, control bleeding, place stents, laser or debulk obstructing tumor, and perform difficult intubation.
A thin flexible scope with a light and camera is passed through the mouth or nose (or through an existing endotracheal or tracheostomy tube) past the vocal cords into the trachea and down the bronchial tree. Channels in the scope allow suction, saline instillation, brushes, needles and tiny biopsy forceps. Washings, brushings, bronchoalveolar lavage and transbronchial biopsies are collected as the airways are inspected; a rigid scope under general anesthesia is used instead when massive bleeding, a large foreign body or major airway work is expected.
Severe refractory hypoxemia, unstable hemodynamics or life-threatening arrhythmias, and uncorrected bleeding disorders or severe thrombocytopenia — particularly if biopsy is planned. Severe uncontrolled asthma, recent myocardial infarction, unstable angina, and an uncooperative patient who cannot be safely sedated are relative contraindications. Elevated intracranial pressure and severe uremia raise the risk.
Hypoxemia, laryngospasm and bronchospasm, arrhythmias, hypotension from sedation, aspiration while the gag is suppressed, fever and post-procedure pneumonia, bleeding from biopsy sites, and airway trauma or perforation. Pneumothorax is a specific risk after transbronchial biopsy — sudden dyspnea, chest pain, absent breath sounds on one side and tracheal deviation are the emergency picture. Hemorrhage after biopsy can be brisk. Airway edema after the scope is withdrawn can produce stridor and obstruction, which is an emergency.
Copious secretions or active bleeding obscure the view. Sampling error means a negative biopsy does not rule out cancer, and prior antibiotics reduce the yield of cultures. Peripheral lesions beyond the reach of the scope may be inaccessible without guidance techniques.
Confirm informed consent is signed before sedation is given. NPO for about 6 to 8 hours (commonly NPO after midnight) to reduce aspiration risk. Check allergies to lidocaine and other local anesthetics, sedatives and latex; review anticoagulants, antiplatelets and aspirin with the provider for hold instructions, and check CBC, platelets and coagulation studies. Obtain baseline vital signs, oxygen saturation and a respiratory assessment; document baseline breath sounds. Remove dentures, bridges and partial plates. Establish IV access, give ordered premedication such as atropine to dry secretions and a benzodiazepine or opioid for sedation, and explain that a local anesthetic spray will make the throat feel thick and swallowing feel odd — but that the airway is not blocked. Warn that the patient will not be able to speak while the scope is in place, and agree on a hand signal.
The patient is usually semi-Fowler or supine with the neck slightly extended. Topical anesthetic is sprayed or gargled and more is instilled through the scope. Moderate sedation is titrated while the nurse continuously monitors level of consciousness, oxygen saturation, cardiac rhythm, respiratory effort and blood pressure, and keeps oxygen, suction, emergency airway equipment and reversal agents at the bedside. The nurse reassures the patient, coaches slow breathing through the nose, labels and routes specimens, and watches for desaturation, stridor and arrhythmia.
Keep the patient NPO — no food, no fluids, not even ice chips — until the gag and swallow reflexes return, typically about 1 to 2 hours; test with a teaspoon of water only after the gag reflex is confirmed present. Position semi-Fowler with the head elevated, or side-lying if not fully alert, to protect the airway. Monitor vital signs and oxygen saturation frequently per protocol, and assess for the emergencies: stridor, hoarseness worsening into respiratory distress, dyspnea, or wheezing (laryngospasm, bronchospasm or airway edema); sudden pleuritic chest pain with dyspnea and diminished unilateral breath sounds (pneumothorax — get a chest x-ray and notify the provider immediately); and more than blood-streaked sputum, which suggests hemorrhage. Reassure that a sore throat, hoarseness and small amounts of blood-tinged sputum for a day are expected. Low-grade fever within the first 24 hours is common, but a persistent or rising fever with productive cough suggests pneumonia. Do not let a sedated patient go home or drive unaccompanied.
Abnormal findings include bronchogenic carcinoma and metastatic tumor, inflammatory or infectious processes such as tuberculosis, fungal infection and Pneumocystis pneumonia, sarcoidosis and interstitial lung disease, bronchiectasis, strictures, foreign bodies, sources of hemoptysis, and airway compression from mediastinal disease.
Nothing by mouth until the gag reflex returns — and treat new stridor, unilateral absent breath sounds, or frank bleeding after bronchoscopy as an airway or hemorrhagic emergency, not as expected soreness.
Smooth, pink, moist mucosa with a normal vascular pattern and normal haustral folds throughout the segment examined; no polyps, masses, ulcers, diverticular inflammation, strictures or active bleeding. Biopsies show no dysplasia or malignancy.
Colonoscopy is the definitive study for the colon: colorectal cancer screening and surveillance, evaluation of a positive stool blood or stool DNA test, iron deficiency anemia, rectal bleeding, unexplained change in bowel habits, chronic diarrhea, and diagnosis plus surveillance of inflammatory bowel disease. It is therapeutic as well — polypectomy, control of bleeding, dilation of strictures, decompression of volvulus, stent placement. Flexible sigmoidoscopy examines only the rectum, sigmoid and descending colon to about 60 cm; it is faster, needs lighter prep and often no sedation, but it cannot exclude disease in the proximal colon, so a lesion found on sigmoidoscopy usually earns a full colonoscopy.
A long flexible video scope is advanced through the anus and around the colon, in colonoscopy as far as the cecum and terminal ileum. Air or carbon dioxide is insufflated to open the lumen so the mucosa can be seen, which is why the patient feels bloating and cramping. Working channels allow suction, biopsy forceps, snares for polyp removal, and cautery.
Suspected or known perforation, fulminant colitis or toxic megacolon, and acute severe diverticulitis — the insufflation and scope can perforate an inflamed or already compromised colon. Also avoid in hemodynamically unstable patients, in peritonitis, and in the recently repaired bowel until cleared by surgery. Uncorrected coagulopathy, severe thrombocytopenia and an incomplete or unsafe bowel prep are relative contraindications. In pregnancy the procedure is deferred unless clearly necessary.
Perforation and hemorrhage are the two serious complications, and both may present hours to days after the patient goes home — bleeding is most common after polypectomy. Vasovagal reactions with bradycardia and hypotension, oversedation with respiratory depression, aspiration, arrhythmias, transient bacteremia, post-polypectomy electrocoagulation syndrome, and bowel prep complications including dehydration and electrolyte disturbance (especially in older adults and patients with renal or cardiac disease) also occur. Severe abdominal pain, distention, rigidity, fever, tachycardia and hypotension after the procedure mean perforation until proven otherwise and require immediate provider notification.
An inadequate bowel prep is the single biggest limitation — retained stool hides polyps and can force a repeat. Barium retained from a recent contrast study, active heavy bleeding, severe diverticular disease, a redundant or fixed colon, and prior pelvic surgery with adhesions can all prevent a complete examination to the cecum. Flat and right-sided lesions are more easily missed.
Verify signed consent before sedation. Reinforce the bowel prep — usually a clear liquid diet the day before with an oral lavage or osmotic prep solution, often split-dosed with part taken the morning of the procedure; teach the patient to avoid red, purple and orange liquids that mimic blood, and to keep drinking clear fluids to stay hydrated. NPO for solids about 8 hours and clear liquids typically stopped 2 to 4 hours before, per facility policy. Review anticoagulants, antiplatelets, insulin and diabetes medications with the provider — holds are individualized against thrombotic risk. Check allergies, obtain IV access and baseline vitals, and ask about implanted devices and prior abdominal surgery. For flexible sigmoidoscopy the prep is lighter, often one or two enemas the morning of the test, and sedation is often not required.
The patient is placed in the left lateral (Sims) position with knees drawn toward the chest, and may be repositioned or have abdominal pressure applied to help the scope advance. Moderate sedation or monitored anesthesia is titrated; the nurse monitors level of consciousness, respiratory rate, oxygen saturation, cardiac rhythm and blood pressure continuously and keeps suction, oxygen and reversal agents available. The nurse also drapes for privacy, coaches breathing through the cramping, and labels biopsy and polyp specimens accurately by site.
Monitor vital signs until the patient is awake and stable, and keep the patient on the side until alert to protect the airway. Expect cramping and passage of flatus — encourage it, since expelling insufflated air relieves the bloating. Resume diet as ordered once alert with an intact gag and swallow, advancing gradually; push fluids to correct prep-related losses. Check the first stools for gross blood. Teach the discharge red flags explicitly and in writing: severe or worsening abdominal pain, a rigid or rapidly distending abdomen, fever, chills, persistent vomiting, dizziness or fainting, and more than a small amount of rectal bleeding or passage of clots. Any of these mean return immediately — perforation and post-polypectomy bleeding can appear up to two weeks later. No driving, operating machinery or signing legal documents for 24 hours after sedation, and the patient must be discharged to a responsible adult.
Abnormal findings include adenomatous and serrated polyps, colorectal carcinoma, ulcerative colitis and Crohn disease, diverticulosis and diverticulitis, ischemic colitis, infectious colitis, angiodysplasia and other bleeding sources, strictures, hemorrhoids and anal fissures on the distal exam.
Severe abdominal pain with distention, rigidity, fever or tachycardia after a lower endoscopy is perforation until proven otherwise — the patient must know these signs before discharge, because most of them appear after they leave.
Smooth, pink cervical and vaginal epithelium with a normal squamocolumnar junction, a normal fine vascular pattern, no acetowhite change, no mosaicism, no punctation and no atypical vessels; directed biopsies show no dysplasia or malignancy.
Ordered to find the source of an abnormal cervical cytology (Pap) result or a positive high-risk HPV test, to evaluate a cervix that looks or bleeds abnormally even with normal cytology, to investigate unexplained postcoital or intermenstrual bleeding, to follow patients after treatment for dysplasia, and to examine women with in utero DES exposure. It answers the question the Pap cannot: exactly where the abnormal cells are and how severe the lesion is on tissue.
A speculum opens the vagina and the cervix is washed with dilute acetic acid (and sometimes an iodine solution). A colposcope — a lighted binocular magnifier that stays outside the body — is focused on the cervix so the examiner can see abnormal epithelium, which turns white with acetic acid, and abnormal vessel patterns. Suspicious areas are biopsied under direct vision, and an endocervical curettage may be added to sample the canal.
Heavy menstrual bleeding or active cervicitis or pelvic infection, which obscure the view and should be treated first — reschedule. Biopsy is usually deferred in pregnancy unless cancer is suspected, and endocervical curettage is contraindicated in pregnancy. Uncorrected bleeding disorders are a relative contraindication to biopsy.
Generally low risk. Bleeding from biopsy sites is the main one and is usually controlled with a hemostatic agent such as Monsel solution or silver nitrate; heavy bleeding is uncommon. Infection, pelvic pain and cramping, and vasovagal syncope during the exam can occur. In pregnancy, biopsy carries a small risk of significant bleeding.
Menstrual blood, semen, vaginal creams, douching, tampons and recent intercourse can obscure the epithelium — the exam is usually scheduled when the patient is not menstruating and after avoiding these. A lesion that lies entirely within the endocervical canal may not be visible, making the colposcopy unsatisfactory or inadequate, which usually requires further sampling.
Explain the procedure clearly and get consent; anxiety is high because the patient already knows a Pap was abnormal, so address the fear that this means cancer. Schedule outside menses when possible. Instruct the patient to avoid intercourse, douching, tampons and vaginal medications for about 24 to 48 hours beforehand. No NPO status and no sedation are needed for a routine office colposcopy. Ask about pregnancy and about anticoagulant use, and suggest a mild analgesic such as ibuprofen about an hour before if biopsy is planned and not contraindicated. Have the patient empty her bladder.
The patient is in the lithotomy position, draped for privacy and dignity — stay at the bedside and talk her through each step. The nurse assists with the speculum, hands the acetic acid and biopsy instruments, and prepares and labels specimen containers by site. Warn her that the acetic acid stings a bit and that a biopsy feels like a sharp pinch or strong cramp. Watch for pallor, sweating, lightheadedness and bradycardia, which signal a vasovagal response — lower the head of the table and stop if needed.
Have her sit up slowly and stay a few minutes before standing to prevent syncope. Teach that a dark, gritty, coffee-ground-looking discharge for a few days is normal after Monsel solution, along with mild cramping and spotting. Instruct her to use pads, not tampons, and to avoid intercourse, douching and tub baths for the period the provider specifies (commonly about a week after biopsy) so the site heals. Report heavy bleeding that soaks a pad in an hour or is heavier than a period, foul-smelling discharge, fever, chills or severe pelvic pain — these suggest hemorrhage or infection. Emphasize that she must call for her biopsy results and keep follow-up; loss to follow-up is the real danger with cervical dysplasia.
Findings identify low- and high-grade squamous intraepithelial lesions (cervical intraepithelial neoplasia), invasive cervical carcinoma, HPV-related changes including condyloma, atrophic or inflammatory changes, and vaginal or vulvar intraepithelial neoplasia when those areas are examined.
Colposcopy is a diagnostic step, not a treatment — the nursing priority is making sure the patient understands the results and returns for follow-up, because untreated high-grade dysplasia is what becomes cancer.
A patent urethra of normal caliber, smooth pink bladder mucosa without tumors, ulcers, stones or trabeculation, a bladder of normal capacity, and two ureteral orifices in normal position with clear efflux of urine. Prostatic urethra is not obstructing in males.
Ordered to see inside the lower urinary tract. It evaluates gross or persistent microscopic hematuria, recurrent or unresolving urinary tract infections, chronic irritative voiding symptoms, urinary retention and obstruction, suspected bladder cancer and its surveillance, stones, strictures, fistulas and interstitial cystitis. Therapeutically it allows biopsy and tumor resection, stone removal or fragmentation, stricture dilation, stent placement and removal, ureteral catheterization for retrograde pyelography, and stopping bladder bleeding.
A rigid or flexible scope is passed through the urethra into the bladder while sterile irrigating fluid distends the bladder so the entire mucosal surface can be inspected. The examiner sweeps the scope systematically over the bladder walls, dome, trigone and ureteral openings, then examines the urethra on withdrawal. Instruments passed through the scope allow biopsy, cautery, basket retrieval of stones and stent placement.
Acute urinary tract infection or prostatitis — instrumenting an infected tract can drive bacteria into the bloodstream and cause urosepsis. Treat the infection first. Also avoid with an acute abdomen, uncorrected coagulopathy, or hemodynamic instability. Severe urethral stricture may make passage impossible.
Urinary tract infection and urosepsis are the most important — fever, chills, flank pain, tachycardia and hypotension after cystoscopy are a medical emergency. Also urethral or bladder trauma and perforation, hematuria, urinary retention from urethral edema (particularly in men with prostatic enlargement), urethral stricture over the long term, and bladder spasms. Perforation presents with lower abdominal pain, distention, rigidity and absent urine output. Sedation and anesthesia carry their usual risks.
Active bleeding clouds the irrigating fluid and limits visualization. A bladder that will not distend because of pain, small capacity or spasm limits the exam, and severe urethral stricture may prevent complete inspection. Sampling error is possible — a negative biopsy does not exclude cancer elsewhere in the urothelium.
Verify signed consent. Determine the planned anesthesia — a flexible office cystoscopy is done with topical lidocaine jelly and no NPO requirement, while a rigid cystoscopy under general or spinal anesthesia requires NPO, typically about 8 hours for solids and 2 hours for clear liquids. Confirm there is no active urinary tract infection; a urinalysis and culture are commonly obtained beforehand. Check allergies including latex and local anesthetics, review anticoagulants with the provider, and give ordered prophylactic antibiotics. Have the patient void before the procedure unless a full bladder is requested, obtain IV access if sedation is planned, and prepare the patient for the sensations of pressure and urgency and the burning that will follow.
The patient is placed in the lithotomy position with legs in stirrups — move both legs together into and out of stirrups to protect the hips and back, and pad pressure points to avoid peroneal nerve injury. Strict sterile technique is used for the perineal prep and draping. The nurse monitors vital signs, oxygenation and comfort, watches irrigation inflow and outflow, and helps the awake patient breathe through the urge to void. Specimens of urine, washings and biopsies are labeled and routed.
Monitor vital signs and, critically, urine output and its appearance. Pink-tinged urine and burning on urination for the first day or two are expected; bright red urine, clots, or a drop in output are not. Assess for urinary retention — an inability to void within about 8 hours, suprapubic distention and discomfort require notification and possible catheterization. Push fluids, generally 2 to 3 liters a day unless contraindicated, to dilute the urine, flush the tract and reduce clot formation and burning. Warm sitz baths, moist heat over the lower abdomen and ordered analgesics or antispasmodics relieve spasm; check for an order before giving an antispasmodic to a patient who is not voiding. Report immediately: fever above 38.3 C or 101 F with chills, flank pain, worsening lower abdominal pain with distention and rigidity, frank bleeding or clots, and no urine output — these indicate urosepsis, obstruction or perforation.
Abnormal findings include bladder and urethral tumors, bladder stones, strictures, urethral and bladder diverticula, benign prostatic hyperplasia with obstruction, trabeculation from chronic outlet obstruction, interstitial cystitis with glomerulations, fistulas, inflammation and infection, and abnormally positioned or refluxing ureteral orifices.
Fever with chills and flank pain after cystoscopy is urosepsis until proven otherwise — and any patient who cannot void within about 8 hours needs assessment for retention, not reassurance.
A smooth, pale pink, uniformly patent ductal lining without intraluminal masses, papillary excrescences, wall irregularity or abnormal vascularity; ductal lavage cytology negative for atypical or malignant cells.
Ordered mainly for pathologic nipple discharge — spontaneous, unilateral, single-duct discharge that is bloody or serous — when mammography, ultrasound and cytology have not found a cause. It answers whether the discharge comes from an intraductal papilloma, ductal carcinoma in situ or an invasive cancer, and it can localize the lesion within the duct so surgical excision is targeted rather than blind. It is also used selectively to map the extent of intraductal disease before breast-conserving surgery and in some high-risk screening protocols.
The discharging duct orifice is identified on the nipple and gently dilated with fine probes. A very small-caliber fiberoptic endoscope, well under a millimeter in diameter, is threaded into the duct while saline is instilled to distend it, and the ductal lining is inspected on a monitor as the scope advances toward the lesion. Cells can be washed out for cytology, and the lesion site can be marked to guide the surgeon.
Acute mastitis, breast abscess or infected nipple skin — do not instrument an infected duct. Absence of a cannulable duct orifice, and nipple retraction or scarring that prevents access, make the procedure impossible. It is not the study of choice for a palpable mass, which needs imaging and core biopsy instead.
Generally minor, but include duct perforation or a false passage, bleeding, infection and mastitis, pain, and local anesthetic reaction. Post-procedure inflammation of the duct can occur. The more clinically important hazard is a false-negative result that delays a cancer diagnosis, so a negative ductoscopy does not close the workup when suspicion remains.
Very small caliber, tortuous or previously scarred ducts limit how far the scope can pass. Ducts that are not discharging at the time of the exam may be hard to identify. Blood or debris in the lumen clouds the view, and lesions in branches beyond the reach of the scope are missed. Cytology from lavage has limited sensitivity on its own.
Confirm consent and explain that the study is done through the nipple opening, with the breast intact — patients often assume an incision. Tell the patient not to express or squeeze the nipple for a day or two before, because the discharge helps identify the correct duct. It is usually an outpatient procedure with local anesthetic and sometimes light sedation; follow facility NPO policy if sedation is planned, typically about 6 to 8 hours for solids. Check allergies to local anesthetics. Ask about anticoagulant use. Address the anxiety directly — many of these patients are being worked up for possible cancer.
The patient is supine with the breast exposed and prepped. Local anesthetic is applied to the nipple and areola. The nurse assists with duct dilation, keeps the field sterile, monitors comfort and vital signs, and collects and labels lavage fluid for cytology; note which duct and which breast on every specimen. Reassure the patient during the pressure and stinging sensations.
Assess the nipple and breast for bleeding, swelling and expanding hematoma. Apply a light dressing and a supportive bra as ordered. Teach that mild soreness, small amounts of blood-tinged discharge and slight bruising for a few days are expected. Report fever, increasing breast pain, redness, warmth, induration or purulent discharge — these signal mastitis or abscess and need prompt treatment. Emphasize follow-up: the patient must return for cytology and pathology results, and a normal ductoscopy does not end surveillance if discharge persists.
Findings identify intraductal papilloma (the most common cause of bloody single-duct discharge), papillomatosis, duct ectasia, intraductal hyperplasia with or without atypia, ductal carcinoma in situ, and invasive ductal carcinoma.
A normal-appearing duct does not rule out cancer — if pathologic nipple discharge continues, the patient still needs follow-up imaging and surgical evaluation, and the nurse's job is to make sure she knows that.
Smooth pink esophageal mucosa with a normal squamocolumnar junction and a competent-appearing lower esophageal sphincter, normal gastric rugae with no ulcers or masses, and a normal duodenal bulb and second portion. Biopsies negative for Helicobacter pylori, dysplasia and malignancy.
Ordered to look directly at the esophagus, stomach and duodenum. It answers why the patient has dysphagia, odynophagia, persistent heartburn, unexplained epigastric pain, nausea and vomiting, early satiety or weight loss; it identifies the source of upper GI bleeding (hematemesis, coffee-ground emesis, melena); it evaluates strictures, suspected ulcer disease, esophageal varices, celiac disease and Barrett esophagus with its surveillance. It is heavily therapeutic — banding or sclerosing varices, injecting or clipping bleeding ulcers, dilating strictures, removing foreign bodies, placing feeding tubes and stents, and removing polyps.
A flexible video endoscope is passed through the mouth, over the tongue and past the pharynx into the esophagus, then advanced through the stomach into the duodenum. Air is insufflated to open the lumen and the mucosa is inspected on the way in and again on withdrawal. Instruments through the working channel take biopsies, cauterize, band, dilate and retrieve.
Suspected or known perforation of the esophagus or stomach — an absolute contraindication. Also avoid in shock or hemodynamic instability that has not been resuscitated, in an unprotected airway with obtundation and high aspiration risk (intubate first), in severe respiratory distress, and in a patient with a recent myocardial infarction who is unstable. Uncorrected coagulopathy, a full stomach, and a large Zenker diverticulum increase risk. In an acute GI bleed the study is often done urgently but only after resuscitation and airway protection.
Perforation of the esophagus, stomach or duodenum is the most serious mechanical complication — it presents with severe persistent chest, epigastric or back pain, dyspnea, fever, subcutaneous emphysema (crepitus at the neck or chest) and signs of shock, and it is a surgical emergency. Bleeding after biopsy, polypectomy or dilation can be significant. Aspiration pneumonia is a major risk because the gag reflex is suppressed. Also expect risk of oversedation with respiratory depression and hypotension, arrhythmias and hypoxemia, vasovagal reactions, infection and transient bacteremia, and reactions to sedatives or topical anesthetic.
Retained food or blood in the stomach obscures the mucosa and can force a repeat — an inadequate NPO period is the usual reason. Recent barium studies leave residue that blocks the view; the endoscopy should come first or be delayed. Sampling error is possible, and some lesions such as early Barrett dysplasia require multiple targeted biopsies to detect.
Verify signed informed consent before any sedation. NPO for about 8 hours for solids, with clear liquids typically stopped 2 to 4 hours before, per policy; gastroparesis or obstruction may need longer. Check allergies to local anesthetics, sedatives and latex. Review anticoagulants, antiplatelets, insulin and oral diabetes agents with the provider for individualized hold instructions, and check CBC and coagulation studies. Remove dentures, partial plates and eyeglasses. Establish IV access, get baseline vital signs and oxygen saturation, and ask about loose teeth and prior difficult airways. Explain the topical throat spray will make swallowing feel strange, that a bite block will be placed, and that the patient will not be able to talk while the scope is in.
The patient is positioned left lateral with the head of the bed slightly elevated so secretions pool in the cheek and drain out, which reduces aspiration risk. A bite block protects the scope and the teeth. Moderate sedation is titrated; the nurse continuously monitors level of consciousness, respiratory rate and effort, oxygen saturation, cardiac rhythm and blood pressure, keeps oral suction active for pooled saliva, and keeps oxygen, airway equipment and reversal agents immediately available. The nurse also supports the patient's head, keeps the bite block in place, and labels biopsy specimens.
Keep the patient strictly NPO until the gag and swallow reflexes return — usually 1 to 2 hours after topical anesthesia. Check the gag reflex before offering anything, then start with sips of water and advance as tolerated. Keep the patient side-lying until fully alert. Monitor vital signs and oxygen saturation per protocol, and assess for the emergency signs of perforation: severe or increasing chest, shoulder, epigastric or back pain, difficulty or painful swallowing that worsens, dyspnea, fever, tachycardia, crepitus in the neck or chest wall, and a rigid abdomen — notify the provider immediately. Signs of bleeding include hematemesis, melena, hypotension, tachycardia and falling hemoglobin. Expect and reassure about a mildly sore throat, hoarseness and bloating from insufflated air; encourage belching. Do not discharge a sedated patient without a responsible adult, and instruct no driving, alcohol or important decisions for 24 hours.
Findings include gastroesophageal reflux disease with esophagitis, hiatal hernia, esophageal and gastric varices, Barrett esophagus and dysplasia, esophageal and gastric carcinoma, peptic ulcer disease of the stomach and duodenum, gastritis and Helicobacter pylori infection, Mallory-Weiss tears, strictures and achalasia-related changes, celiac disease on duodenal biopsy, and foreign bodies.
Check the gag reflex before anything goes in the mouth after an EGD, and treat new severe chest or abdominal pain with fever, dyspnea or neck crepitus as perforation — call the provider, keep the patient NPO, do not wait to see if it improves.
A structurally normal fetus for gestational age with normal external features, normal limbs and digits, normal facial and spinal anatomy, and normal appearing placental vasculature and umbilical cord; any fetal blood or tissue samples obtained are normal on laboratory analysis.
A highly specialized procedure done only at fetal treatment centers. It is used to look directly at the fetus when imaging cannot answer the question — suspected structural anomalies of the face, limbs, spine or skin, and certain genetic syndromes — and to obtain fetal blood or skin biopsy when those specimens are required for diagnosis. Its bigger role today is therapeutic: laser photocoagulation of placental anastomoses in twin-to-twin transfusion syndrome, fetoscopic balloon tracheal occlusion for severe congenital diaphragmatic hernia, cord occlusion in complicated monochorionic twins, and release of amniotic bands.
Under continuous ultrasound guidance, a very thin fiberoptic endoscope is passed through the maternal abdominal and uterine wall into the amniotic cavity, usually through a small incision or trocar with local or regional anesthesia. The clear amniotic fluid acts as the viewing medium, so the fetus and the placental surface can be seen directly. Fine instruments and a laser fiber can be introduced alongside the scope for sampling or treatment.
Active maternal infection including chorioamnionitis, hepatitis or HIV with high viral load where instrumentation raises transmission risk; placenta previa or an anterior placenta positioned so there is no safe entry window; severe oligohydramnios that leaves no fluid to see through; preterm labor or ruptured membranes; maternal coagulopathy; and cervical incompetence. It is not appropriate when a less invasive test such as detailed ultrasound, MRI, amniocentesis or cell-free DNA can answer the question.
This is the highest-risk procedure in this group for the fetus. Complications include premature rupture of membranes, preterm labor and preterm delivery, chorioamnionitis, amniotic fluid leak, placental abruption, bleeding, fetal injury from the instruments, fetal bradycardia and fetal death or pregnancy loss. For the mother: infection, bleeding, uterine injury, amniotic fluid embolism (rare but catastrophic), pulmonary edema, and anesthesia complications. Rh sensitization can occur in an Rh-negative mother if fetal blood mixes with maternal blood.
A poor acoustic and optical window limits everything — an anterior placenta, maternal obesity, reduced or cloudy amniotic fluid, fetal position and advancing gestational age with a crowded uterus all restrict what can be seen. The field of view is narrow, so a normal fetoscopy does not exclude anomalies outside the visualized area.
This is a major, emotionally loaded procedure; consent must be truly informed and include the real risk of pregnancy loss, and it should be documented after counseling by the maternal-fetal medicine specialist. Confirm gestational age and obtain baseline ultrasound. NPO per anesthesia plan, generally about 8 hours for solids and 2 hours for clear liquids. Draw type and screen, CBC and coagulation studies. Verify Rh status — RhoGAM is given to Rh-negative mothers. Check allergies. Obtain baseline maternal vital signs and a baseline fetal heart rate. Give ordered prophylactic antibiotics and tocolytics. Have the patient empty her bladder, establish IV access, and give the mother and her partner space to ask questions and express fear.
The mother is positioned supine with a wedge under the right hip, or in a left lateral tilt, to displace the uterus off the vena cava and prevent supine hypotensive syndrome. Local, regional or general anesthesia is used depending on the procedure. The nurse monitors maternal vital signs, oxygen saturation and pain, monitors fetal heart rate as directed, assists with continuous ultrasound guidance, maintains strict sterile technique, and handles any fetal specimens with care and precise labeling. Watch for maternal hypotension and for fetal bradycardia.
Monitor maternal vital signs and continuous or intermittent fetal heart rate per protocol. Assess the puncture site for bleeding and the abdomen for tenderness or rigidity. Assess specifically and repeatedly for: leaking amniotic fluid or a sudden gush (rupture of membranes), uterine contractions or cramping (preterm labor), vaginal bleeding (abruption), fever, chills, uterine tenderness or foul discharge (chorioamnionitis), and decreased fetal movement or non-reassuring fetal heart tracing — any of these require immediate provider notification. Administer Rh immune globulin to Rh-negative mothers as ordered. Bed rest and activity restriction are commonly ordered, along with pelvic rest. Teach the warning signs in writing before discharge and ensure close follow-up ultrasound.
Abnormal findings confirm structural fetal anomalies such as facial clefts, limb and digital malformations, neural tube defects and skin disorders; identify the abnormal placental vascular connections of twin-to-twin transfusion syndrome; and, through fetal blood or skin sampling, diagnose hemoglobinopathies, coagulation disorders, congenital infection and certain genetic skin diseases.
After fetoscopy, any leaking fluid, contractions, vaginal bleeding, fever or decreased fetal movement is reported immediately — the procedure's defining risks are membrane rupture, preterm labor, infection and fetal loss.
A symmetric uterine cavity with smooth pink endometrium appropriate to the cycle phase, both tubal ostia visible, and no polyps, submucosal fibroids, adhesions, septum or masses.
Ordered to see inside the uterine cavity. It evaluates abnormal uterine bleeding, postmenopausal bleeding, infertility and recurrent pregnancy loss, suspected intrauterine adhesions or a uterine septum, retained products of conception, a misplaced or embedded IUD, and abnormal findings on ultrasound or sonohysterogram. Operatively it removes polyps and submucosal fibroids, lyses adhesions, resects a septum, performs endometrial ablation and directed biopsy, and places tubal occlusion devices.
A thin lighted scope is passed through the vagina and cervix into the uterus, so no abdominal incision is needed. The cavity is distended with a fluid medium such as saline or a nonelectrolyte solution, or with carbon dioxide, so the walls separate and can be inspected on a monitor. Operative instruments, loops or energy devices pass through the scope's channel to cut or remove tissue.
Known or suspected pregnancy, active pelvic infection or cervicitis, and known cervical cancer are contraindications. Heavy active uterine bleeding obscures the view and usually postpones the test. Recent uterine perforation and inability to distend the cavity are also contraindications. In pregnancy the procedure risks the gestation directly.
Uterine perforation is the classic complication, and it can injure bowel, bladder or vessels — sharp abdominal pain, distention, rigidity, shoulder pain and signs of shock are the emergency picture. Fluid overload with hyponatremia and, with nonelectrolyte media, dilutional hyponatremic encephalopathy is a serious and underappreciated risk of operative hysteroscopy; the fluid deficit must be tracked meticulously. Also possible are hemorrhage, infection and endometritis, cervical laceration from dilation, gas embolism when carbon dioxide is used (sudden dyspnea, chest pain, hypotension, cardiovascular collapse), thermal injury from energy devices, and intrauterine adhesion formation later.
Heavy bleeding, blood clots, mucus or debris cloud the distention medium. A thick secretory endometrium can hide small lesions, so the exam is best scheduled in the early proliferative phase just after menses. Cervical stenosis may prevent entry, and an enlarged or markedly distorted cavity limits complete inspection.
Verify signed consent. Confirm the patient is not pregnant — obtain a pregnancy test. Schedule in the early follicular phase, after menstrual flow ends, when the endometrium is thin. NPO per the anesthesia plan; office diagnostic hysteroscopy may need no NPO, but general or regional anesthesia requires roughly 8 hours for solids and 2 hours for clear liquids. Check allergies and review anticoagulants. A cervical ripening agent such as misoprostol may be ordered the night before or a few hours before to ease dilation — teach the patient to expect cramping and spotting from it. Give ordered analgesia or antibiotics, have the patient void, and establish IV access if sedation is planned.
Lithotomy position with careful, simultaneous leg placement and padded stirrups to protect nerves and joints. The nurse maintains sterile technique, assists with cervical dilation, and — this is the key nursing role in operative cases — accurately measures distention fluid inflow and outflow and reports the running deficit to the surgeon, because unrecognized absorption causes hypervolemia and hyponatremia. Monitor level of consciousness, vital signs, oxygen saturation, and watch for the sudden dyspnea, hypotension and desaturation of gas embolism. Label specimens by site.
Monitor vital signs, pad count and pain. Expect mild to moderate cramping, spotting or light bleeding for a few days, and shoulder pain if carbon dioxide was used, since gas irritates the diaphragm; ambulation and heat help. Assess neurologic status and electrolytes when large fluid volumes were used — confusion, nausea, headache, visual changes, lethargy or seizures point to hyponatremia and require immediate notification. Report heavy bleeding soaking a pad an hour or more, severe or worsening abdominal pain, abdominal distention or rigidity, fever above 38 C, foul-smelling discharge, dizziness or fainting. Teach pelvic rest — nothing in the vagina, no intercourse, tampons, douching or tub baths — for the period the provider specifies. No driving for 24 hours after sedation.
Abnormal findings include endometrial polyps, submucosal leiomyomas, intrauterine adhesions (Asherman syndrome), congenital anomalies such as a uterine septum or bicornuate cavity, endometrial hyperplasia and carcinoma, retained products of conception, and displaced intrauterine devices.
During and after operative hysteroscopy, track the distention fluid deficit and the patient's mental status — fluid absorption with hyponatremia can kill a patient who looks like she only had a minor gynecologic procedure.
Normal-appearing liver, gallbladder, spleen, stomach, bowel and peritoneal surfaces with no adhesions, masses, implants or free fluid; in women, normal uterus, tubes and ovaries with no endometriotic implants, cysts or adhesions.
Ordered when the abdomen or pelvis must be seen and imaging is not conclusive. It diagnoses chronic pelvic pain, endometriosis, infertility and tubal disease, ectopic pregnancy, pelvic inflammatory disease and adnexal masses; it evaluates unexplained abdominal pain, staging of intra-abdominal cancers, ascites, and liver disease with directed biopsy; and it is used in trauma and in acute abdomen when the diagnosis is unclear. Most laparoscopy today is also operative — cholecystectomy, appendectomy, hernia repair, lysis of adhesions, ablation of endometriosis, tubal ligation, oophorectomy and hysterectomy.
A small incision, usually at or below the umbilicus, admits a needle or trocar and the abdomen is insufflated with carbon dioxide to lift the abdominal wall away from the organs and create a working space. A lighted laparoscope is inserted and the interior is viewed on a monitor, with additional small port incisions for instruments. At the end, the gas is released and the port sites are closed.
Generalized peritonitis with hemodynamic instability, massive abdominal distention or bowel obstruction with distended loops that the trocar could puncture, and uncorrected coagulopathy. Extensive prior abdominal surgery with dense adhesions is a relative contraindication because of the risk of bowel injury at entry. Severe cardiopulmonary disease tolerates the pneumoperitoneum and steep positioning poorly. Advanced pregnancy and large abdominal masses limit access.
Injury to bowel, bladder, ureter or a major vessel during trocar insertion is the most feared complication and may not be recognized during the case — a bowel injury can declare itself a day or more later with fever, escalating pain and peritonitis. Hemorrhage, infection, and port-site hernia occur. The pneumoperitoneum itself causes referred shoulder and subdiaphragmatic pain, decreased venous return and hypotension, decreased lung compliance with hypercapnia and acidosis, subcutaneous emphysema, and rarely carbon dioxide gas embolism, which presents as sudden hypotension, hypoxia, arrhythmia and cardiovascular collapse. Steep Trendelenburg adds risks of nerve injury, facial and airway edema, and aspiration. DVT and thermal injury from electrosurgery round out the list.
Dense adhesions from prior surgery or infection, obesity, massive obesity of the omentum, active bleeding, and bowel distention all limit visualization and may force conversion to an open procedure. Small or deep lesions and retroperitoneal structures may not be seen.
Verify signed surgical consent, including consent for possible conversion to an open laparotomy — patients must know this in advance. NPO after midnight or per anesthesia guidance, commonly about 8 hours for solids and 2 hours for clear liquids. Check allergies including latex, review and hold anticoagulants and antiplatelets per the surgeon, and check CBC, coagulation studies, type and screen, and a pregnancy test in women of childbearing age. Give ordered bowel prep or antibiotics. Have the patient void or insert a urinary catheter as ordered to keep the bladder out of the trocar path, and place an orogastric or nasogastric tube if ordered to decompress the stomach. Apply sequential compression devices, obtain baseline vital signs, teach coughing, deep breathing and early ambulation, and warn about shoulder pain afterward so it is not frightening.
The patient is supine, often in Trendelenburg for pelvic work or reverse Trendelenburg for upper abdominal work, with arms tucked and all pressure points padded and the patient well secured to the table before tilting. General anesthesia with an endotracheal tube is standard because the pneumoperitoneum and positioning compromise ventilation. The circulating nurse maintains sterile technique, performs sponge, sharp and instrument counts, monitors insufflation pressure and end-tidal carbon dioxide trends with the anesthesia provider, watches for subcutaneous emphysema, and manages specimens.
Monitor vital signs, oxygenation and level of consciousness during recovery. Assess incision sites for bleeding, drainage and swelling. Teach that shoulder and neck pain from residual carbon dioxide is expected for one to two days and is relieved by walking, position changes, heat and analgesia — early ambulation both clears the gas and prevents DVT and atelectasis. Assess bowel sounds and the return of flatus, and monitor urine output. Report immediately: increasing rather than decreasing abdominal pain, a rigid or distended abdomen, fever and tachycardia, absent bowel sounds with vomiting, hypotension or a falling hemoglobin, hematuria or absent urine output, and expanding subcutaneous crepitus — these point to bowel or bladder injury, hemorrhage or peritonitis. Teach incision care and give clear written return precautions before discharge.
Findings identify endometriosis, pelvic adhesions, tubal occlusion and hydrosalpinx, ovarian cysts and tumors, ectopic pregnancy, pelvic inflammatory disease, appendicitis, gallbladder disease, cirrhosis and other liver pathology on biopsy, peritoneal carcinomatosis and metastatic implants, and causes of unexplained ascites.
Abdominal pain that is getting worse instead of better after laparoscopy is not gas pain — with fever, distention or hypotension it means bowel injury or bleeding, and it needs the surgeon now.
Normal-sized, soft, non-matted mediastinal lymph nodes and normal mediastinal structures; biopsy shows no granulomas, no malignant cells and no evidence of metastatic disease.
The principal use is staging lung cancer — determining whether tumor has spread to mediastinal lymph nodes, which changes whether the patient is a surgical candidate. It is also used to diagnose mediastinal masses and lymphadenopathy of unclear cause, including sarcoidosis, lymphoma, tuberculosis and other granulomatous disease, when less invasive sampling has failed or is not feasible.
Under general anesthesia, a small transverse incision is made just above the sternal notch and the surgeon creates a plane down along the front of the trachea with a finger, then inserts a rigid lighted scope into the mediastinum. Paratracheal and subcarinal lymph nodes are visualized and biopsied through the scope. The incision is small, but the working space lies among the great vessels, the trachea and the recurrent laryngeal nerves.
Prior mediastinoscopy or prior mediastinal irradiation, because scarring obliterates the tissue plane and greatly raises the risk of vascular injury. Superior vena cava syndrome with distended collateral veins, a thoracic aortic aneurysm, severe tracheal deviation, uncorrected coagulopathy, and inability to tolerate general anesthesia or neck extension (severe cervical spine disease) are contraindications.
This procedure has small but genuinely life-threatening complications. Hemorrhage from injury to the great vessels (innominate artery, azygos vein, pulmonary artery) can be catastrophic and may require emergency sternotomy. Pneumothorax, tracheal or esophageal injury, air embolism, chylothorax, infection and mediastinitis, and recurrent laryngeal nerve injury causing hoarseness and vocal cord paralysis all occur. Phrenic nerve injury can cause diaphragmatic paralysis. Sudden dyspnea, chest pain, unilateral absent breath sounds, tracheal deviation, hypotension, expanding neck swelling, or stridor after the procedure are emergencies.
Only certain node stations are reachable through this approach — nodes in the subaortic, aortopulmonary window and posterior or inferior mediastinum may require a different approach, so a negative result does not exclude disease in unsampled stations. Adhesions and prior treatment limit access, and sampling error is possible.
Verify signed surgical consent; the patient must understand that a thoracotomy or sternotomy may be needed if bleeding occurs, and in some settings the surgeon plans to proceed directly to resection if nodes are negative — clarify what the consent covers. NPO after midnight or per anesthesia, generally about 8 hours for solids and 2 hours for clear liquids. Obtain CBC, coagulation studies, type and crossmatch, chest imaging and pulmonary function results; review anticoagulant and antiplatelet holds. Check allergies. Establish IV access, document baseline vital signs, breath sounds, oxygen saturation and — importantly — baseline voice quality, so postoperative hoarseness can be recognized. Address the anxiety of a patient who is being staged for possible cancer.
The patient is supine with the neck hyperextended and a roll under the shoulders to open the sternal notch. General anesthesia with endotracheal intubation is used. Blood pressure monitoring and pulse checks may be done on both arms, because scope pressure on the innominate artery can dampen the right-sided pulse and produce a falsely low right arm reading. The circulating nurse maintains sterile technique, keeps blood products available, performs counts, and labels each node station specimen separately, since the station determines the cancer stage.
Monitor vital signs closely, and assess the neck incision and surrounding tissue for swelling, hematoma and bleeding — an expanding neck hematoma can compress the airway. Assess breath sounds bilaterally, respiratory effort and oxygen saturation for pneumothorax; a chest x-ray is usually obtained. Assess voice quality and swallowing for recurrent laryngeal nerve injury, and check for subcutaneous crepitus. Notify the provider immediately for hypotension and tachycardia with falling hemoglobin, sudden dyspnea or chest pain with unilateral absent breath sounds and tracheal deviation, stridor or expanding neck swelling, fever with sternal or chest pain and leukocytosis (mediastinitis), or new hoarseness with choking on liquids. Provide analgesia, teach incisional splinting for coughing, and give written signs to report after discharge.
Positive nodes indicate metastatic spread of lung or other cancer, which usually makes the tumor unresectable and shifts treatment to chemotherapy and radiation. Noncaseating granulomas suggest sarcoidosis; caseating granulomas with positive cultures suggest tuberculosis or fungal infection; and characteristic architecture on node biopsy diagnoses lymphoma.
Mediastinoscopy is a small incision over the great vessels — treat hypotension, an expanding neck swelling, or sudden dyspnea with absent unilateral breath sounds as hemorrhage or pneumothorax and get help immediately.
Pink, moist nasal and sinus mucosa with patent sinus ostia and normal drainage pathways, no polyps, no purulent secretions, a midline or non-obstructing septum, and normally shaped turbinates.
Ordered for chronic or recurrent sinusitis that does not respond to medical therapy, nasal obstruction, anosmia, chronic postnasal drainage and facial pressure, recurrent epistaxis, suspected nasal polyps or a nasal mass, cerebrospinal fluid rhinorrhea, and to obtain culture directly from the sinus rather than relying on a contaminated nasal swab. Operatively it opens obstructed ostia, removes polyps and diseased tissue, corrects anatomic obstruction, and gives access to the orbit and skull base.
A rigid or flexible endoscope, usually a few millimeters wide, is passed into the nasal cavity after the mucosa is decongested and anesthetized topically. Angled lenses let the examiner look up into the middle meatus and the drainage openings of the maxillary, ethmoid, frontal and sphenoid sinuses. Diagnostic endoscopy is a brief office procedure; operative endoscopic sinus surgery is done under general anesthesia with instruments and a powered shaver.
For diagnostic endoscopy there are few real contraindications; avoid instrumenting during acute epistaxis that is not controlled, and use caution with severe coagulopathy or thrombocytopenia. For surgery, uncorrected coagulopathy and acute untreated infection extending beyond the sinuses are contraindications. Anatomic distortion or prior surgery near the skull base raises risk and calls for image guidance.
Diagnostic endoscopy is low risk — mostly epistaxis, discomfort, sneezing, gagging and a vasovagal response. Operative endoscopic sinus surgery carries far more serious risks because the sinuses border the orbit and the anterior skull base: significant hemorrhage, orbital injury with hematoma, diplopia or vision loss, cerebrospinal fluid leak from a skull base breach with the risk of meningitis, injury to the lacrimal duct, anosmia, synechiae and infection. Clear watery drainage from one nostril that increases with leaning forward, a salty or metallic taste, or a positional headache after sinus surgery suggests a CSF leak and must be reported at once. Proptosis, orbital swelling, eye pain or change in vision is an emergency.
Blood, thick purulent secretions and severe mucosal edema block the view; decongestion beforehand improves it considerably. A markedly deviated septum, turbinate hypertrophy or scarring from prior surgery can prevent passage of the scope into the middle meatus, and disease deep within a sinus may not be visible from the ostium alone, so CT imaging is complementary.
For office diagnostic endoscopy: explain the procedure, obtain consent per policy, and apply topical decongestant and anesthetic spray, allowing it several minutes to work. No NPO is required and no sedation is typically used. For operative endoscopic sinus surgery: verify signed surgical consent, NPO for about 8 hours for solids and 2 hours for clear liquids, hold anticoagulants, antiplatelets and NSAIDs per the surgeon since bleeding obscures the surgical field, check CBC and coagulation studies, and confirm allergies. Ask about aspirin sensitivity with asthma and nasal polyps, a triad that matters here. Teach the patient not to blow the nose afterward.
For diagnostic endoscopy the patient sits upright with the head slightly extended; the nurse coaches slow breathing through the mouth, provides tissues and an emesis basin, and watches for pallor or lightheadedness. For surgery, the patient is supine with the head of the bed elevated slightly, under general anesthesia with a throat pack in place to catch blood — make sure removal of the pack is documented. The nurse maintains sterile technique, tracks blood loss, and labels specimens and cultures.
Elevate the head of the bed to reduce edema and bleeding. Apply ice or a cool compress across the nose as ordered, and change the drip pad under the nose, noting the amount of drainage. Teach the patient not to blow the nose, and to sneeze with the mouth open, for the period the surgeon specifies — usually one to two weeks — because blowing forces air into the tissues and can restart bleeding or worsen a skull base leak. Avoid straining, heavy lifting and bending; give stool softeners as ordered. Expect blood-tinged drainage and nasal congestion for several days. Report immediately: persistent bright red bleeding or frequent swallowing (which suggests blood running down the throat), clear watery unilateral drainage or a persistent salty taste (possible CSF leak), fever with neck stiffness, headache or altered mental status (meningitis), and eye swelling, proptosis, pain or any visual change (orbital complication). Encourage saline irrigation once the surgeon permits it, and use humidification.
Findings include chronic rhinosinusitis with mucosal thickening and purulence, nasal polyposis, anatomic obstruction from septal deviation or a concha bullosa, fungal sinusitis, inverted papilloma and sinonasal malignancy, foreign bodies, and CSF leak sites.
After sinus surgery, clear unilateral watery drainage, a salty taste, or any change in vision or eye swelling means a skull base or orbital complication — report it immediately and do not let the patient blow the nose.
A smooth, glistening, thin visceral and parietal pleura with no nodules, plaques, adhesions or effusion; normal-appearing lung surface that expands fully; pleural biopsy negative for malignancy, granuloma and infection.
Ordered to see and biopsy the pleural space, lung surface and, in surgical form, the lung itself. It is the study of choice for a recurrent or exudative pleural effusion whose cause remains unknown after thoracentesis and pleural fluid analysis, for suspected mesothelioma or pleural metastasis, for staging thoracic malignancy, and for tuberculous pleuritis. Therapeutically it drains loculated effusions and empyema, performs pleurodesis to prevent recurrence, resects lung nodules and lobes, treats recurrent pneumothorax, and creates a pericardial window.
Under general anesthesia (or local with sedation for medical thoracoscopy), one or more small incisions are made between the ribs and a lighted scope is inserted into the pleural space. The lung on that side is allowed to partially collapse, usually with a double-lumen tube that ventilates only the opposite lung, so there is room to see and work. Instruments through additional ports allow biopsy, resection and pleurodesis, and a chest tube is placed through one of the incisions at the end.
Obliterated pleural space from dense adhesions — there is nowhere to put the scope. Also avoid in patients who cannot tolerate single-lung ventilation, in severe refractory hypoxemia, in hemodynamic instability, in uncorrectable coagulopathy, in uncontrolled cough, and in severe pulmonary hypertension. Contralateral lung disease severe enough that the patient depends on both lungs is a major limitation.
Persistent air leak and bronchopleural fistula, hemorrhage, pneumothorax after chest tube removal, empyema and wound infection, subcutaneous emphysema, re-expansion pulmonary edema when a large effusion is drained too quickly, injury to lung, diaphragm, intercostal vessels or nerve with chronic post-thoracotomy neuralgia, arrhythmias, respiratory failure, and tumor seeding of port sites in mesothelioma. Sudden severe dyspnea with tracheal deviation, hypotension, distended neck veins and absent breath sounds is a tension pneumothorax and is an immediate emergency.
Dense pleural adhesions or a completely fused pleural space prevent adequate inspection and are the most common reason the procedure fails or is converted. Loculated fluid, extensive tumor and poor lung deflation limit the view. Lesions deep within the lung parenchyma are not visible from the pleural surface without palpation or localization techniques.
Verify signed surgical consent, including consent for possible conversion to open thoracotomy and for chest tube placement. NPO after midnight or per anesthesia — about 8 hours for solids, 2 hours for clear liquids. Obtain CBC, coagulation studies, type and crossmatch, chest imaging, pulmonary function tests and arterial blood gases as ordered; hold anticoagulants and antiplatelets per the surgeon. Check allergies. Document a thorough baseline respiratory assessment — breath sounds in all fields, respiratory rate and effort, oxygen saturation and any oxygen requirement. Teach incentive spirometry, splinted coughing, deep breathing and early ambulation before the procedure, when the patient can actually learn it, and explain that a chest tube will be in place afterward and what it will feel like.
The patient is placed in the lateral decubitus position with the affected side up and the arm raised, with an axillary roll and all pressure points padded; positioning injuries are common with this posture. General anesthesia with a double-lumen endotracheal tube permits one-lung ventilation. The nurse maintains sterile technique, monitors oxygenation and hemodynamics with the anesthesia team during single-lung ventilation, performs counts, manages the chest drainage system setup, and labels pleural fluid and biopsy specimens.
This is chest tube nursing. Assess respiratory status frequently — rate, effort, symmetry of chest expansion, breath sounds bilaterally and oxygen saturation. Keep the drainage system below chest level, keep tubing free of dependent loops and kinks, and never routinely strip or milk the tubing. Assess for tidaling (normal), for an air leak in the water seal chamber (expect some initially; report a new or worsening one), and measure drainage — sudden bright red output greater than about 100 mL per hour, or a sudden stop in a previously draining tube, should be reported. Assess for subcutaneous emphysema by palpating around the insertion site for crepitus. Elevate the head of the bed, provide adequate analgesia so the patient will breathe deeply, and enforce incentive spirometry, coughing and early ambulation to prevent atelectasis and pneumonia. Emergencies to report immediately: sudden severe dyspnea with unilateral absent breath sounds, tracheal deviation, hypotension and distended neck veins (tension pneumothorax); frothy pink sputum, crackles and hypoxemia after rapid drainage (re-expansion pulmonary edema); fever with purulent drainage (empyema); and hemodynamic instability with a falling hemoglobin (hemorrhage).
Findings identify malignant pleural effusion and pleural metastases, mesothelioma, tuberculous and other infectious pleuritis, empyema, asbestos-related pleural plaques, benign and malignant lung nodules on wedge biopsy, interstitial lung disease on surgical lung biopsy, and the cause of recurrent pneumothorax.
After thoracoscopy the chest tube system is the patient's lifeline — keep it below the chest, patent and intact, and treat sudden dyspnea with tracheal deviation and absent breath sounds as a tension pneumothorax requiring immediate intervention.
