[Bouveret syndrome diagnosed by endoscopy].

The case of a 74 years old woman suffered from a gallstone disease for 5 years is reported. In the background of the upper abdominal pain and vomiting, which necessitated her hospitalization, a large-size gallstone penetrated into the duodenal bulb and obstructed pyloric channel was found by endoscopic examination. The upper duodenal ileus was verified during the operation, gastroduodenotomy and cholecystectomy were performed, and the 7 x 4 cm size gallstone was removed. After a complications free period the asymptomatic patient went home. Our above reported case is a preoperatively, endoscopically diagnozed Bouveret's syndrome.
