[Bouveret syndrome].

Bouveret syndrome, a rare form of gallstone ileus predominantly encountered in elderly female patients, is clinically characterized by the sequelae of duodenal obstruction. Two patients observed within one year are presented and the clinical, diagnostic and therapeutic aspects of the disease are discussed. The surgical treatment of choice is one-stage removal of stone, closure of fistula and cholecystectomy completed by a careful search for residual stones in the small and large intestine.
