Perforation of a hollow viscus

A hollow viscus perforation is a full-thickness breach in the wall of a gastrointestinal organ, allowing gas, gastrointestinal contents, bacteria, bile, or faeces to escape into the peritoneal cavity. It commonly produces secondary peritonitis, sepsis, and may rapidly progress to septic shock.

Common sites and causes

SiteImportant causes
Stomach/duodenumPerforated peptic ulcer, malignancy, trauma, iatrogenic injury
Small bowelTyphoid, tuberculosis, Crohn disease, strangulation/ischemia, trauma, foreign body
AppendixPerforated acute appendicitis
ColonDiverticulitis, colorectal cancer, volvulus with ischemia, inflammatory bowel disease, stercoral perforation
RectumTrauma, instrumentation, malignancy
Any bowel segmentAnastomotic leak, endoscopy-related perforation, blunt or penetrating trauma
Bailey and Love lists gastrointestinal perforation such as perforated ulcer, appendicitis, and diverticulitis as a principal route to peritoneal infection. Bailey and Love's Short Practice of Surgery, 28th ed., p. 1109.

Pathophysiology

  1. Leakage initially causes chemical peritonitis, particularly with gastric acid, bile, pancreatic juice, or faecal contamination.
  2. Bacterial contamination follows or occurs simultaneously.
  3. The peritoneum mounts an inflammatory response, causing fluid sequestration, paralytic ileus, hypovolaemia, and systemic inflammatory response.
  4. The omentum and adjacent bowel may contain the leak, causing localized peritonitis or abscess.
  5. Uncontained contamination causes generalized peritonitis, sepsis, multiorgan dysfunction, and death if untreated.

Clinical features

Symptoms
  • Sudden severe abdominal pain, often initially localized to the site of perforation
  • Pain worsened by movement, coughing, or deep inspiration
  • Nausea, vomiting, anorexia
  • Fever and progressive abdominal distension
  • Shoulder-tip pain when diaphragmatic peritoneum is irritated
Signs
  • Patient lies still, often with knees flexed
  • Tachycardia, fever, dehydration
  • Localized or generalized tenderness
  • Guarding, board-like rigidity, and rebound tenderness
  • Reduced or absent bowel sounds due to paralytic ileus
  • Late: hypotension, confusion, oliguria, septic shock
Bailey and Love describes peritonitis as pain aggravated by movement/coughing/deep breathing, with tenderness, guarding or rigidity, reduced bowel sounds, tachycardia, fever, and late septic shock. Bailey and Love's Short Practice of Surgery, 28th ed., p. 1110.

Investigations

  • Blood tests: CBC, electrolytes, renal function, liver tests, serum lactate, blood gas, coagulation profile, group and cross-match, blood cultures if septic.
  • Erect chest radiograph: may demonstrate free subdiaphragmatic gas.
  • CT abdomen and pelvis with IV contrast: preferred test in stable patients. It identifies free intraperitoneal air, site/cause of perforation, fluid collections, abscess, ischemia, and obstruction.
  • A normal plain X-ray does not exclude perforation.
Erect chest X-ray and CT showing intraperitoneal perforation
Bailey and Love figure: erect chest radiograph can show free air beneath the right hemidiaphragm in intraperitoneal perforation. Bailey and Love's Short Practice of Surgery, 28th ed., p. 1110.

Management

This is a surgical emergency in a patient with generalized peritonitis, sepsis, free perforation, or hemodynamic instability.

Initial resuscitation

  • ABCDE assessment and oxygen as required
  • Two large-bore IV lines
  • Rapid IV crystalloid resuscitation and correction of electrolyte deficits
  • Nil by mouth
  • Nasogastric tube for decompression
  • Urinary catheter and hourly urine-output monitoring
  • Adequate analgesia and antiemetics
  • Early broad-spectrum IV antibiotics covering enteric Gram-negative organisms and anaerobes
  • Blood cultures before antibiotics if this does not delay treatment
  • Early senior surgical and anesthetic involvement

Definitive source control

  • Urgent laparoscopy or laparotomy when diffuse peritonitis, ongoing leak, sepsis, or clinical deterioration is present.
  • Objectives:
    1. Identify the perforation.
    2. Control the leak.
    3. Repair, resect, divert, or exteriorize the diseased segment as appropriate.
    4. Remove gross contamination with peritoneal lavage.
    5. Drain selectively where indicated.
Examples:
  • Small perforated peptic ulcer: primary closure, with or without omental patch.
  • Perforated appendix: appendicectomy plus washout.
  • Small-bowel perforation: primary repair if small and viable, otherwise segmental resection with anastomosis or stoma depending on contamination and physiology.
  • Colonic perforation: resection with primary anastomosis or stoma based on stability, degree of contamination, bowel viability, and underlying disease.
Bailey and Love summarizes management of peritonitis as fluid/electrolyte correction, nasogastric drainage, urinary catheterization, broad-spectrum antibiotics, analgesia, organ support, and surgical source control with treatment of the cause plus peritoneal lavage with or without drainage. Bailey and Love's Short Practice of Surgery, 28th ed., p. 1110. This aligns with WSES intra-abdominal infection guidance, which emphasizes prompt source control by repair or resection of the perforated viscus.

Complications

  • Generalized peritonitis and intra-abdominal abscess
  • Septic shock and multiorgan dysfunction
  • Wound infection and wound dehiscence
  • Anastomotic leak or enterocutaneous fistula
  • Ileus, adhesional intestinal obstruction
  • Respiratory and thromboembolic complications
  • Death, especially with delayed presentation, fecal peritonitis, advanced age, or severe comorbidity
One-line exam answer:
Perforation of a hollow viscus is a surgical emergency causing secondary peritonitis due to escape of air and contaminated gastrointestinal contents into the peritoneal cavity; management is immediate resuscitation, broad-spectrum antibiotics, imaging in stable patients, and timely operative source control.
