Abstract

Ischemic colitis is the most common ischemic injury of the gastrointestinal tract. It can result from ischemia caused by compromised blood flow to the mesenteric arteries. Colonic ischemia may be precipitated by several conditions, although a cause is not clearly identified in most cases. A 63-year-old man was admitted because of loss of consciousness with melena. After endoscopic bleeding control of Dieulafoy lesions of the stomach, hematochezia occurred during the in-hospital care period. A sigmoidoscopy and computed tomography scan were conducted to evaluate the hematochezia, and ischemic colitis was diagnosed. Here, we report a case of ischemic colitis associated with massive upper gastrointestinal bleeding. (Korean J Gastrointest Endosc 2011;42:255-258)
