[Bouveret's syndrome. Two new cases (author's transl)].

Pyloro-duodenal obstruction by a gall-stone which has passed through a bilio-digestive fistula (Bouveret's syndrome) is rare. The authors report two cases. The clinical picture is that of pyloric obstruction. The diagnosis, suspected on barium meal, is today confirmed by fibre endoscopy. The treatment is fairly simple: cholecystectomy, removal of the gall stone, closure of the fistula; the prognosis depends on the general context.
