[A rare cause of gastric outlet obstruction: Bouveret's syndrome].

Bouveret's syndrome is a rare type of gallstone ileus in which a gallstone enters the intestinal tract via a cholecystoenteric fistula and is lodged in the duodenum or the stomach. Since the first description by León Bouveret in 1896, fewer than 200 cases have been described in the worldwide literature. Mortality is high, at 25%, but may be related to the advanced age of the typical patient and comorbidities, as well as diagnostic delay. Diagnosis may be made with radiological (abdominal X-ray, ultrasound, computed tomography or magnetic resonance imaging) and endoscopic techniques. Endoscopy is preferred as the first therapeutic option but is frequently unsuccessful and surgery is often required. We present the case of a patient admitted to hospital with a history of vomiting after eating and epigastric pain. The management of this rare cause of gastric outlet obstruction is discussed.
