Esophageal Perforation

Esophageal perforation rapidly converts a local injury into mediastinitis, sepsis, and multiorgan failure. Mortality rises sharply when diagnosis and source control are delayed, especially beyond the first 24 hours.

A 52-year-old man doubles over in the emergency department, one hand pressed to his lower chest and the other gripping a basin. His shirt is damp with sweat, and he says the pain began suddenly after a violent episode of retching at dinner. He now feels short of breath and describes a strange fullness in his neck, while his blood pressure drifts downward on the monitor. The next diagnostic and therapeutic move has not yet been made.

— What’s your move? Read on.

Before you read

What imaging strategy confirms the diagnosis without worsening the perforation?
Which patients need urgent operative or endoscopic source control?

When to Think of It

Enter the diagnosis with severe chest or epigastric pain after vomiting, instrumentation, foreign-body ingestion, or thoracic trauma—particularly when accompanied by fever, dyspnea, dysphagia, subcutaneous emphysema, pneumomediastinum, pleural effusion, or unexplained shock.

Sick or Not Sick

The key fork is physiologic instability or uncontrolled contamination versus a stable, contained cervical or thoracic leak. Shock, respiratory failure, diffuse mediastinal/pleural contamination, free perforation, or an uncontained abdominal perforation demands immediate surgical consultation and resuscitation.

The First Fifteen Minutes

Keep the patient NPO, place on cardiac/SpO₂ monitoring, obtain two large-bore IVs, and call surgery and GI early.
If hypoxemic, provide oxygen; if respiratory failure develops, perform a controlled intubation with the most experienced airway operator because positive pressure can worsen mediastinal contamination.
If hypotensive, give balanced crystalloid 500–1,000 mL IV boluses, reassessing lungs and perfusion after each; volume restores preload but excess fluid worsens pulmonary edema and tissue edema.
If hypotension persists after initial fluid, start norepinephrine 0.05–0.1 mcg/kg/min IV infusion, titrated to MAP ≥65 mmHg; α₁-mediated vasoconstriction restores perfusion pressure.
Give piperacillin-tazobactam 4.5 g IV now, then every 6 hours; it covers enteric gram-negative organisms, anaerobes, and many gram-positive organisms entering the mediastinum. Adjust for renal function and verify local protocol if severe renal impairment.
If immediate broad coverage with piperacillin-tazobactam is unsuitable, use cefepime 2 g IV plus metronidazole 500 mg IV; this provides gram-negative and anaerobic coverage, but local resistance patterns matter.
Give fluconazole or an echinocandin only after specialist discussion for critically ill patients with prolonged contamination, prior healthcare exposure, or Candida risk; routine empiric antifungal therapy is not required.
For severe pain, give fentanyl 25–50 mcg IV, repeated every 5 minutes to effect while monitoring ventilation; analgesia reduces catecholamine stress without masking the need for source control.
Obtain CBC, CMP, lactate, coagulation studies, type and crossmatch, blood cultures if this will not delay antibiotics, and a portable chest radiograph. Proceed to CT chest/upper abdomen with IV contrast plus water-soluble oral contrast when the patient can safely cooperate; avoid blind NG or oral contrast administration without specialist direction.

Definitive Care & Disposition

Stable patients with a small, contained cervical or thoracic leak, minimal contamination, and no distal obstruction may undergo nonoperative management with NPO status, IV antibiotics, acid suppression, drainage when needed, and serial imaging under surgical/GI supervision. Free perforation, sepsis, large leak, distal obstruction, nonviable tissue, or pleural/mediastinal contamination generally requires operative repair, washout, drainage, or endoscopic closure/stenting. Admit all confirmed cases to an ICU-capable setting; arrange enteral or parenteral nutritional support after the anatomy and leak are defined. Do not place a blind NG tube.

How This One Kills

The lethal error is treating chest pain and pneumomediastinum as a benign post-emesis finding, delaying antibiotics and drainage while mediastinitis progresses to septic shock.

The Differential — What Else Looks Like This

Acute coronary syndrome — ischemic ECG/troponin pattern without pneumomediastinum; confusing the two delays source control, while anticoagulation may worsen procedural bleeding.
Spontaneous pneumothorax — unilateral pleuritic pain with absent breath sounds but no esophageal leak; anchoring on it misses mediastinal contamination.
Perforated peptic ulcer — free intraperitoneal air and peritonitis centered in the abdomen; assuming an esophageal source can misdirect operative planning.
Mallory-Weiss tear — hematemesis from mucosal laceration without transmural leak; confusing it with perforation can delay hemorrhage-focused care, while missing perforation is catastrophic.

The Second-Day Story

Older adults, immunocompromised patients, and those already receiving antibiotics may have little pain or fever. They may present with delirium, tachypnea, leukocytosis, unexplained pleural effusion, or sepsis after endoscopy rather than dramatic vomiting and subcutaneous emphysema. A mechanism involving retching or instrumentation plus new mediastinal air, pleural fluid, or shock should trigger CT-based evaluation even when the examination is quiet.

Back to Our Patient

Back to our 52-year-old man: the abrupt post-retching chest pain, dyspnea, hypotension, and neck crepitus make esophageal perforation the leading diagnosis. He is sick, so the priority is monitored resuscitation with IV access, cautious crystalloid, norepinephrine if needed, analgesia, and immediate broad-spectrum IV antibiotics while obtaining CT with water-soluble oral contrast and involving surgery and GI. Imaging reveals distal esophageal extravasation with mediastinal air and a contaminated left pleural effusion, prompting urgent operative washout and repair with pleural drainage. He is admitted to the ICU for source-control management, ventilatory monitoring, and nutritional planning.

Patient Presentation to Attending

How you’d present this patient on the floor — tight, pertinent positives and negatives, no rambling

“This is a 52-year-old man with abrupt severe lower chest pain and dyspnea after forceful vomiting at dinner, now with borderline hypotension and neck crepitus. He has no prior cardiac history, and the pain is not exertional; he denies hematemesis, but he is tachypneic and appears toxic. Examination shows subcutaneous emphysema, left-sided chest tenderness, and reduced breath sounds at the left base without focal neurologic deficits. ECG has no STEMI pattern, and chest radiograph shows pneumomediastinum with a left pleural effusion. I’m concerned for spontaneous distal esophageal perforation with mediastinal and pleural contamination. I’m keeping him NPO, obtaining CT chest and abdomen with IV and water-soluble oral contrast, giving broad-spectrum IV antibiotics and cautious resuscitation, and involving surgery, GI, and critical care now.”

The Case

A 29-year-old woman sits curled around her abdomen, counting the trips she has made to the bathroom since sunrise. Her water bottle is empty, her lips are dry, and streaks of blood mark the toilet paper beside the bed. She says the diarrhea is now mixed with urgency and cramping, but the room grows quiet when she mentions a new fever and a swollen, tender abdomen. The next step in deciding whether this is a flare—or something more dangerous—has not yet occurred.

Before You Read

Which findings define acute severe ulcerative colitis and change the level of care?
What must be excluded before escalating immunosuppression?
Which medications should be avoided because they can precipitate catastrophic complications?

Why It Matters

IBD flares can cause profound dehydration, anemia, electrolyte abnormalities, sepsis, and toxic megacolon. The emergency clinician must distinguish an uncomplicated flare from infection, perforation, obstruction, or fulminant colitis.

When to Think of It

Consider IBD with recurrent bloody diarrhea, abdominal pain, urgency, weight loss, extraintestinal manifestations, or known Crohn disease/ulcerative colitis. Red flags include fever, tachycardia, hypotension, severe anemia, marked leukocytosis, elevated CRP, inability to maintain hydration, severe tenderness, distension, or systemic toxicity.

Sick or Not Sick

The central call is stable flare versus acute severe colitis, toxic megacolon, perforation, or sepsis. In ulcerative colitis, acute severe disease is typically ≥6 bloody stools/day plus systemic toxicity such as tachycardia, fever, anemia, or elevated inflammatory markers; these patients require admission and early GI/surgical involvement.

The First Fifteen Minutes

Place on monitoring, establish IV access, assess volume status, and obtain CBC, CMP, magnesium, CRP/ESR, lactate when ill, type and screen if bleeding, and pregnancy testing when relevant.
Send stool testing for C. difficile, bacterial pathogens, and other indicated infections before immunosuppression; obtain blood cultures if febrile or septic.
If hypovolemic, give balanced crystalloid 500–1,000 mL IV, reassessing perfusion and urine output; it replaces GI losses and corrects preload.
For persistent septic hypotension after fluids, start norepinephrine 0.05–0.1 mcg/kg/min IV, titrated to MAP ≥65 mmHg.
If acute severe ulcerative colitis is likely after infection evaluation is initiated and GI agrees, give methylprednisolone 60 mg IV daily or hydrocortisone 100 mg IV q8h; glucocorticoids suppress the inflammatory cascade. Dose selection varies by protocol—verify with GI/institutional guidance.
If toxic megacolon, perforation, or systemic toxicity is suspected, give piperacillin-tazobactam 4.5 g IV q6h; it covers enteric organisms during barrier failure and sepsis. Adjust for renal function.
For nausea, give ondansetron 4 mg IV or ODT q6h PRN, which reduces vomiting without slowing intestinal motility as strongly as anticholinergic agents.
For severe pain, use acetaminophen 650–1,000 mg PO/IV, keeping total daily dose ≤3 g in significant liver disease; avoid NSAIDs because they can worsen mucosal inflammation and renal injury. Avoid routine opioids because they increase ileus and toxic-megacolon risk.
If admitted with an active flare and no major bleeding, give enoxaparin 40 mg SC daily for venous-thromboembolism prophylaxis; IBD inflammation creates substantial thrombosis risk.

Definitive Care & Disposition

Obtain CT abdomen/pelvis with IV contrast when perforation, obstruction, abscess, or toxic megacolon is suspected; obtain plain abdominal imaging promptly for significant distension or systemic toxicity. Admit acute severe colitis, inability to hydrate, severe electrolyte derangement, significant bleeding, or suspected complication. GI should assess response to IV steroids within 2–3 days and consider rescue infliximab or cyclosporine; surgery is urgent for perforation, uncontrolled hemorrhage, worsening toxic megacolon, or failure of medical rescue. Avoid antidiarrheals, anticholinergics, and opioids in severe colitis.

How This One Kills

The catastrophic error is labeling toxic megacolon as an ordinary flare and giving antimotility drugs or opioids, increasing colonic dilation until perforation and septic shock occur.

The Atypical Presentation

Older adults and patients already taking steroids may have little fever or leukocytosis despite severe disease. Crohn disease may present with obstruction, abscess, fistula, or perianal disease rather than diarrhea; ulcerative colitis may present mainly with anemia, tachycardia, and frequent small bloody stools. The combination of stool frequency, systemic physiology, abdominal distension, and laboratory inflammation is more reliable than the patient’s subjective description of a “usual flare.”

Back to Our Patient

Back to our 29-year-old woman: frequent bloody stools, dehydration, fever, and a tender distended abdomen place acute severe colitis and toxic megacolon high on the list rather than a routine outpatient flare. She receives monitored IV fluids, stool testing including C. difficile, laboratory evaluation, VTE prophylaxis, and urgent CT imaging; antimotility drugs and opioids are avoided. Imaging shows marked colonic dilation without perforation, and she is admitted to the ICU for acute severe ulcerative colitis, receives IV corticosteroids and broad-spectrum antibiotics, and undergoes early GI and colorectal surgery consultation. Her response is reassessed closely, with rescue therapy or colectomy planned if she deteriorates or fails medical treatment.

Patient Presentation to Attending

“This is a 29-year-old woman with ulcerative colitis presenting with more than 10 bloody stools today, cramping, fever, dehydration, and new abdominal distension. She has no recent travel, but infectious stool studies are pending; she denies vomiting or focal right-lower-quadrant pain. She is tachycardic with dry mucous membranes and diffuse tenderness, and her abdomen is distended without frank rigidity. Labs show anemia, leukocytosis, hypokalemia, and elevated CRP; abdominal imaging shows colonic dilation without perforation. I’m concerned for acute severe UC with evolving toxic megacolon, so I’m giving IV fluids, correcting electrolytes, starting VTE prophylaxis, avoiding opioids and antidiarrheals, and involving GI and colorectal surgery for monitored admission and IV steroid therapy.”

Study Directive

Memorize the clinical definition and admission features of acute severe ulcerative colitis.
Create a “do not give” list for severe colitis: loperamide, anticholinergics, and routine opioids.
Practice interpreting abdominal radiographs for colonic dilation and identifying when CT is needed.
Review your institution’s steroid, rescue biologic, and VTE-prophylaxis protocols with GI.
Complete five cases distinguishing IBD flare, C. difficile, ischemia, abscess, and toxic megacolon.

Key Medications

Balanced crystalloid 500–1,000 mL IV bolus, reassessing frequently.
Methylprednisolone 60 mg IV daily or hydrocortisone 100 mg IV q8h for acute severe UC after infection evaluation; protocol variability is meaningful—check GI guidance, Lexicomp, UpToDate, or local protocol.
Piperacillin-tazobactam 4.5 g IV q6h for suspected toxic megacolon, perforation, abscess, or sepsis; renal adjustment required.
Norepinephrine 0.05–0.1 mcg/kg/min IV, titrated to MAP ≥65 mmHg.
Enoxaparin 40 mg SC daily for VTE prophylaxis; use 30 mg SC daily in severe renal impairment per many protocols.
Acetaminophen 650–1,000 mg PO/IV, maximum generally 3 g/day in significant liver disease; lower limits may be appropriate.
Ondansetron 4 mg IV/ODT q6h PRN; monitor QT risk.
Rescue biologic and cyclosporine dosing is specialty- and weight-dependent; verify with GI and a current reference.
Pediatric IBD treatment is weight-based and requires pediatric GI involvement.

High-Yield Pearls

A “flare” with distension and systemic toxicity is toxic megacolon until proven otherwise.
IBD carries increased VTE risk even during active GI bleeding; prophylaxis is often still indicated unless bleeding is truly prohibitive.
C. difficile can coexist with IBD and must be tested for before escalating immunosuppression.

The Mimics

C. difficile colitis — recent antibiotics or healthcare exposure with positive testing; steroids alone can worsen uncontrolled infection.
Infectious dysentery — acute exposure-associated bloody diarrhea; immunosuppression before testing may prolong or worsen infection.
Ischemic colitis — abrupt pain and hematochezia in a vascular-risk patient; missing ischemia delays surgery or revascularization.
Appendicitis or intra-abdominal abscess — focal pain or rim-enhancing collection; assuming a flare delays source control.

Board Question

A patient with ulcerative colitis has 12 bloody stools per day, fever, tachycardia, anemia, and abdominal distension. Which medication should generally be avoided?

AEnoxaparin prophylaxis
BIV corticosteroids after infection evaluation
CLoperamide
DPotassium replacement

Reveal answer

Correct: C

Antimotility agents can worsen colonic dilation and precipitate toxic megacolon in severe colitis. VTE prophylaxis and IV corticosteroids are commonly appropriate when indicated, while electrolyte correction is essential.
