Trans-anal small bowel evisceration through a perforation of the rectum: a case report.

Trans-anal small bowel evisceration (TSBE) is a rare, life-threatening surgical emergency, typically presenting with a patient who is unwell. We report an atypical case of a stable 78-year-old female with a history of chronic constipation presenting with a reducible TSBE. Exploratory laparotomy demonstrated an anterior rectal defect. The defect was repaired primarily, and small bowel resection was performed. This case highlights the diagnostic difficulties that clinicians may face due to the rarity of this condition, particularly in a well-appearing patient, and underscores the importance of prompt definitive surgical management.
