Bouveret's syndrome: description of a case.

Bouveret's syndrome is a rare condition usually caused by a single large stone impacted in the duodenum. This is a cause of gastric outlet. Even if endoscopy is the mainstay of diagnosis, the radiographic examinations are also important too. Generally, the stones are too large to be removed endoscopically. Conservative endoscopic treatment should be attempted initially, and if it fails, surgical approach should be performed.
