title: Bouveret's syndrome presenting as upper gastrointestinal hemorrhage.
abstract: A unique case of hematemesis is presented. The cause of upper gastrointestinal bleeding was a pyloroduodenal ulcer caused by erosion of a 5-cm gallstone impacted in the duodenal bulb. On review of the world literature of Bouveret's syndrome, this is the first case in which a preoperative diagnosis was well established and the fourth such case in which a successful surgical outcome was obtained.
