An adult case of intussusception due to inverted meckel's diverticulum resected by laparoscopy-assisted surgery

Abstract

A 59-year-old man consulted our hospital with a chief complaint of intermittent abdominal pain. Abdominal CT revealed an ileo-ileal intussusception caused by a tumor in the small intestine, and double-balloon enteroscopy revealed an ileal tumor 70-cm from the ileocecal valve. We diagnosed the patient as having ileo-ileal intussusception due to tumor of the small intestine, and performed laparoscopy-assisted partial resection of the small intestine including the tumor site. Histopathological findings suggested that the tumor was composed of inverted true diverticulum containing ectopic gastric mucosa ; hence, we finally diagnosed this patient with inverted Meckel's diverticulum. The occurrence of intussusception caused by inversion of Meckel's diverticulum in adults is relatively rare, and hence preoperative diagnosis of the disease is difficult. Herein, we reviewed the Japanese literature on intussusception caused by inverted Meckel's diverticulum and discussed the origin, diagnosis, and optimal therapeutics of this condition.
