Ischemic colitis endoscopy

Overview
Among patients with a suspicion of ischemic colitis, endoscopic evaluation, via colonoscopy or flexible sigmoidoscopy, is the diagnostic procedure of choice if the diagnosis remains unclear after other imaging studies.

Diagnosis
Ischemic colitis has a distinctive endoscopic appearance; endoscopy can also facilitate alternate diagnoses such as infection or inflammatory bowel disease. Biopsies can be taken via endoscopy to provide more information.
