Abstract

Ischemic colitis is the most common form of intestinal ischemia. It is a condition that is commonly seen in the elderly and among individuals with risk factors for ischemia. Common predisposing conditions for ischemic colitis are major vascular occlusion, small vessel disorder, shock, some medications, colonic obstructions and hematologic disorders. Ischemic colitis following colonoscopy is rare. Here, we report two cases of ischemic colitis after a routine screening colonoscopy in patients without risk factors for ischemia.

Keywords: Ischemic colitis; Colonoscopy; Hematochezia

Core tip: Ischemic colitis following colonoscopy is rare and is predominantly involved at the sigmoid colon and splenic flexure. However, our two cases were found on the right side of the colon after a routine screening colonoscopy in patients without risk factors for ischemia. We believe these cases are interesting and instructive for gastroenterologists.
