[A case of relapsed ischemic colitis with colon cast-like stripped mucosa].

ABSTRACT

An 82-year-old woman who had 5 relapses of ischemic colitis was admitted with sudden lower abdominal pain. Colonoscopic examination performed on the 2nd day revealed colon cast-like stripped colonic mucosa in the lower portion of the descending colon. She was treated conservatively. After 2 weeks, ischemic colitis healed, with slight residual stenosis. Most reports of colon cast indicated that colon cast was caused by abdominal aneurysm, operation, or external wound. The only predisposing conditions in this case were arteriosclerosis of abdominal aorta and chronic constipation. Arteriosclerosis and chronic constipation might be the important risk factors of ischemic colitis with colon cast and relapsing of ischemic colitis.
