ABSTRACT
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
