A CASE OF ADULT INTUSSUSCEPTION CAUSED BY INVAGINATED MECKEL'S DIVERTICULUM

Abstract

A case of intussusception due to an invaginated Meckel's diverticulum is reported. A 37-year-old woman was admitted to the hospital because of right lower abdominal pain, diarrhea which lasted for about one month, and recent intermittent colic. Physical examination revealed tenderness of her lower abdomen, however tumor was not palpable. Abdominal ultrasonography (US) and computed tomography (CT) showed target-like appearance on the right lower abdomen. A fluoroscopic examination of the small intestine revealed a bird's beak-like stenosis. These findings suggested intussusception of the small intestine by tumor. Intraoperatively, an invaginated Meckel's diverticulum which led to enteric intussusception was identified. Partial resection of the ileum with end-to-end anastomosis was performed. Histological examination of the resected specimen revealed Meckel's diverticulum containing ectopic pancreato tissue. We reviewed 45 cases of Meckel's diverticulum leading to intussusception and discussed the clinical features.
