Ischemic Enterocolitis Involving the Terminal Ileum and Sigmoid Colon: Report of a Case

A 62-year-old man was admitted because of hemorrhagic shock caused by gastic ulcer bleeding. Three days after admission, frequent watery diarrhea, vomiting and abdominal pain appeared. These symptoms contiuned for 2 months. Barium examination of the small bowel and colorectum demonstrated severe stricture of the terminal ileum and sigmoid colon. Surgery was performed, and no apparent occlusion of the terminal arteries in the lesions was noted. In the resected ileum, a circumferential 6.5-cm-long ulcer was found, and 2 circumferential ulcers were separately present in the sigmoid colon. Microscopic findings revealed non-specific ulceration and hemosiderin in all layers. This was considered to be a rare case of ischemic bowel disease in which 3 separate lesions were apparent in the ileum and sigmoid colon.
