[Bouveret's syndrome: the clinical and radiological findings].

Bouveret's syndrome is an unusual presentation of gallstone ileus, due to duodenal obstruction. It is produced by the migration of biliary calculus through a cholecystogastric or cholecystoduodenal fistula. We present 3 new cases of Bouveret's syndrome, and the clinical and radiological findings on different imaging procedures (plain abdominal radiography, barium studies, ultrasonography and computed tomography). On the basis of these cases, we discuss the diagnostic and possibly therapeutic merits of digestive endoscopy and about the different surgical procedures.
