Bouveret syndrome
Bouveret syndrome, first described in 1896, is the most infrequent variant of gallstone ileus. It results from a gallstone migrating through a bilioenteric fistula, obstructing the gastric outlet and occasionally in other portions of the intestine. The entry point is typically a fistula between the gallbladder and a portion of the stomach or intestine .
It is extremely rare and constitutes 1 to 3% of all obstructions caused by gallstones in the gastrointestinal tract, representing 0.3 to 5% of cholelithiasis complications. (2)
The chance of spontaneous resolution of Bouveret syndrome after conservative treatment is rare and endoscopic intervention is currently the first line of treatment for this syndrome. It generally carries a good prognosis provided there is timely diagnosis and management.(2)
