title: A case of extraperitoneal stoma-associated internal hernia after abdominoperineal resection.
abstract: Published reports concerning internal hernias after extraperitoneal stoma construction are scarce. In our present report, we describe the case of a 56-year-old man who was referred to our hospital for the treatment of rectal cancer. He underwent abdominoperineal resection of the rectum with sigmoidostomy using an extraperitoneal route. On the ninth postoperative day, the patient experienced sudden and intense abdominal pain and was diagnosed with strangulation of the small intestine due to a stoma-associated internal hernia. Therefore, an emergency laparotomy was performed. The surgical findings showed that the small intestine protruded through the space between the sigmoid colon loop and the abdominal wall in a cranial-to-caudal direction. The strangulated portion of the small intestine was recovered, and the orifice of herniation was closed. No recurrence of internal herniation was observed during the follow-up period.
