Although uncommon in the general population, ischemic colitis occurs with greater frequency in the elderly, and is the most common form of bowel ischemia .
Dieulafoy's lesion are typically diagnosed during endoscopic evaluation, usually during upper endoscopy, which may show an isolated protruding blood vessel.
