Abstract
Ischemic colitis is a serious complication of aortic aneurysm resection. A knowledge of the endoscopic appearance and the clinical course of various forms of colonic mucosal injury is important for the clinician who has to decide which patient should be carefully monitored after aneurysm resection. This article reports on 48 patients with colonic mucosal injury, subdivided into non-specific lesions and ischemic colitits. Details are given of the endoscopic picture and the clinical course. It is concluded that only the gangrenous form of ischemic colitis is of clinical significance, and is related to bowel perforation and late stricture formation.
