Abstract
A 17-year-old man was admitted for abdominal distension and was found to have colon gas dilatation or abdominal plain radiography. Based on this, a diagnosis of volvulus of the sigmiod colon was made However, no improvement of the condition could be seen on colonofiberscopy. Under the diagnosis of ileus an emergency operation was performed. On laparotomy, the cecum and the ascending colon were found tc be unattached to the retroperitoneum, and were rotated 360 degrees counterclockwise with strangulation Dilatation and hemorrhagic necrosis were seen to extend from the terminal ileum to the ascending colon and an ileocecal resection was performed. This disease is relatively uncommon and the preoperative diagnosis often presents difficulty. If a strangulated ileus is suspected, we must keep the possibility of thi: disease in mind, and it is most important to perform surgical treatment for this disease.
