Abstract
Trans-anal evisceration of small bowel is a rare surgical presentation. The first case ever reported was in 1827. The exact mechanism of how this develops remains poorly understood. A 70-year-old lady presented with multiple small bowel loops eviscerated through the anus. Abdominal exploration was done. The bowel was carefully reduced. There was a longitudinal defect on the anterior wall of the rectum at the recto-sigmoid junction and a large mesenteric defect and thrombosed mesenteric vessels compromising blood supply to part of the bowel. Resection of 50 cm of ileum, jejunostomy and a mucous fistula were performed. Several preexisting pathologies such as rectal prolapse can result in thinning out of the wall of the rectum. That combined with increased intra-abdominal pressure can explain trans-anal evisceration of the bowel. This condition is managed by surgical intervention. The operation will depend on the extent of viability, contamination and patient's general condition.
