This case report describes a rare complication of small bowel perforation caused by colonoscopic procedures. The patient underwent urgent surgery and recovered well. The possibility of small bowel perforation should be considered during colonoscopy, and urgent exploratory laparotomy is necessary when visceral perforation is identified.
Rationale: Iatrogenic gastrointestinal perforation is a known uncommon complication of colonoscopy. The perforation usually occurs in the colon itself. Rarely, colonoscopic procedures can also cause the perforations of the small intestine. Patient concerns and diagnoses: We describe the case of a 70-year-old man who experienced abdominal pain several hours after electrical polypectomy in the transverse colon. Urgent abdominal computed tomography scans showed a few bubbles on the frontal surface around the liver and a little extraluminal free air in the upper abdomen. Urgent exploratory laparotomy revealed a round perforation with a diameter of approximately 5 mm in the ileum 80 cm proximal to the ileocecal valve, accompanied by the outflow of intestinal contents. A small bowel perforation by thermal injury was diagnosed during colonic polypectomy. Interventions and outcomes: The ileal perforation was repaired primarily after debridement of the perforation site and abdominal cavity. The patient recovered well after surgery. Histopathological examination of the perforation site demonstrated inflammatory necrosis and infiltration of inflammatory cells. Lessons: Small bowel perforation should be considered after colonoscopic procedures although the incidence is exceedingly rare. Urgent exploratory laparotomy is warranted when a visceral perforation is identified after colonoscopy.
