内翻したMeckel憩室が先進部となった成人腸重積症の1例

Abstract

We report a rare case of adult intussusception caused by an inverted Meckel's diverticulum. A 24-year-old man with intermittent abdominal pain was found by abdominal computed tomography to have target sign. We diagnosed intussusception, and couducted emergency surgery. At laparotomy, we found that the ileum had invaginated into the ascending colon. When the intussusception was relieved with Hutchinson's maneuver, an inverted diverticulum was observed at 80cm proximal to the ileocecum. The diverticulum was 7cm in size and was present on the opposite site of the mesentery. Histological findings showed all layers of small intestine and ectopic gastric mucosal tissue in the diverticulum. We diagnosed intussusception due to inverted Meckel' s diverticulum. Inverted Meckel's diverticulum should be considered as a probable cause of intestinal intussusception.
