[Bouveret's syndrome. Case report].

Introduction: Bouveret's syndrome is characterized by piloro-duodenal obstruction following the implant of a giant gallstone with gallstone ileus origin. It constitutes the less common variety of gallstone ileus (1-3%), mainly affecting elderly patients with chronic degenerative illnesses, possibly with high mortality.

Objective: We report the case of a patient with a less common variety of gallstone ileus. The patient was treated at a third-level care hospital.

Clinic Case: Patient is a 52-year-old male with gastric obstruction and secondary dehydration. Studies were supported by a series of esophagus-gastric-duodenal and broad endoscopy. Piloro-duodenal obstruction by a giant gallstone was reported which could not be extracted by endoscopy. The patient was taken to surgery where a giant gallstone lying in the duodenal site was found and biliary vesicular scleroatrophic. Gastrotomy is effected with the extraction of the gallstone and gastrography. Gallstone duodenal fistula is then identified with support analysis.

Conclusions: Bouveret's syndrome is a rare entity whose diagnosis has a high sensitivity and specificity with a supported radiographic diagnosis. Endoscopy is difficult in the case of a giant impacted gallstone, making surgery the best therapeutic choice.
