The case was a 52 year-old male. He visited the clinic on the 5th day of disease with the complaint of abdominal tumor. The abdomen was found slightly distended and soft. A tumor of child head size was felt in the abdomen. It was roughly round in shape and extremely movable. On fluoloscopic examination with barium contrast medium, it was diagnosed as a tumor developed from the transverse colon or its vicinity, and laparotomy was indicated. On laparotomy, the tumor was found at the transverse colon and was found to be an invagination of ileo-cecal region and ascending colon into the transverse colon. Devagination was undertaken easily. Further examination revealed that the transition of ascending colon to the transverse colon was not clearly marked and lacking the hepatic angulation, and that they were extremely movable together with the cecum. Thus, it was confirmed that this was a case of messenterium commune. Further, since the peristalsis of the cecal region was found accelerated, the ileo-cecal region was resected to prevent recurrence.
In the present paper, the case was briefly reported and, as this case of invagination was caused by the messenterium commune, discussions were made on the mechanism of occurrence.
