Bouveret's syndrome: successful endoscopic treatment of gastric outlet obstruction caused by an impacted gallstone.

Bouveret's syndrome is defined as gastric outlet obstruction caused by duodenal impaction of a large gallstone which passes into the duodenal bulb through a cholecystogastric or cholecystoduodenal fistula. This is a report of a 62 years old female who presented with complaint of persistent vomiting and upper abdominal pain for the last 5 days. Ultrasound abdomen was suggestive of pneumobilia. CT scan of upper abdomen showed cholecystoduodenal fistula and complete obstruction of third part of duodenum by a large stone, which was reported as Bouveret's syndrome. She underwent emergency gastroscopy. The stone was retrieved by Dormia basket, crushed with lithotripter and extracted endoscopically.Complete intestinal obstruction was relieved endoscopically.
