A duodenal ulcer initially causes bleeding by eroding the submucosal vessels of the duodenal wall. The base of such an ulcer is characteristically white due to fibrinous exudate and the collagen of the wall.

A visibly pumping vessel was seen in the base of the ulcer. If there is a visible vessel in the bed of an ulcer, there is greater than a 50% chance of rebleeding after initial endoscopic control. This is particularly true of the gastroduodenal artery.
