Bouveret's syndrome: A rare case of gallstone causing gastric outlet obstruction

Abstract

Key Clinical MessageThe case highlights the importance of decisive action in addressing large gallstones causing gastric outlet obstruction. The chosen single‐stage surgical approach reflects the need to manage both obstruction and the gallstone simultaneously.AbstractBouveret's syndrome is a rare cause of gastric outlet obstruction secondary to gallstones entering the enteric system through an acquired cholecystoduodenal fistula. Here, we present the case of an 85‐year‐old female who presented to our emergency department with gastric outlet obstruction secondary to a large gallstone in the third part of the duodenum. Abdominal X‐ray did not demonstrate air‐fluid levels but revealed a dilated gastric shadow, suggesting gastric outlet obstruction. EGD showed a dilated stomach and a hard, golf ball‐sized gallstone in the duodenum. CT scan showed a distended stomach with a large gallstone obstructing the DJ junction and air in the biliary tree. Findings were suggestive of perforation of the gallbladder with stone impaction in the duodenojejunal (DJ) junction. The patient was managed surgically with a one‐stage procedure comprising enterotomy, fistula closure, and cholecystectomy. Although Bouveret's syndrome is rare, it is important for practicing surgeons to have a high index of suspicion for this condition due to the high mortality associated with it.
