Although they account for a minority of episodes of upper gastrointestinal bleeding, the awareness of less frequent causes of upper gastrointestinal bleeding can be crucial to the endoscopist in the evaluation of the patient with bleeding. This review discusses the Dieulafoy lesion, hemobilia, gastric antral vascular ectasia, Mallory-Weiss tear, and gastroduodenal arteriovenous malformation.

D007412	Intestinal Fistula	An abnormal anatomical passage between the INTESTINE, and another segment of the intestine or other organs. External intestinal fistula is connected to the SKIN (enterocutaneous fistula).

Risk factors include inflammatory processes, cancer, radiation treatment, and surgical misadventures (MEDICAL ERRORS).
