ABSTRACT
Bouveret's syndrome is a rare entity consisting in a duodenal obstruction due to the passage of gallstones from the gallbladder to the duodenum through a cholecystoduodenal fistula. Approximately 225 cases are reported in the literature. It is most common in old women with a previous history of biliary tract disease. The clinical picture is nonspecific and pre-operative diagnosis is not easy. Oral endoscopy is the main diagnostic procedure and sometimes, a therapeutic option, too. Surgery is the elective treatment specially when endoscopy is unsuccessful. We report a new case of this syndrome successfully treated by surgery, and an extensive review of the literature concerning this issue, focusing mainly on the clinical findings, diagnosis, therapeutic procedures and results. We conclude that Bouveret's syndrome is rare but more frequent in older females with previous biliary disease, better diagnosed by pyloric obstruction syndrome, plain abdominal x-ray, ultrasonography, contrast gastric study and/or gastroscopy (confirming and best procedure). When conservative endoscopic procedure fails, surgical treatment must be carried out, thus obtaining good results.
