title: Fourth-portion duodenal diverticulum causing massive upper gastrointestinal bleeding.
abstract: Most duodenal diverticula are asymptomatic, incidentally discovered at endoscopy or barium studies. Upper gastrointestinal bleeding has been described, but it is an infrequent complication. We describe the 14th case reported in the literature of massive upper gastrointestinal bleeding originating from a duodenal diverticulum.
