[Spontaneous cholecysto-gastric fistula with massive gastrointestinal bleeding. Endoscopic diagnosis and concrement extraction].

A case of spontaneous cholecysto-gastric fistula is reported with penetration of a gallstone into the stomach leading to massive haemorrhage of gastric mucosa. The gallstone was removed endoscopically, the immanent complication of gallstone ileus could be eliminated. Mucosal bleeding was stopped by conservative methods, and thus enough time was won for optimal preparation for the ensuing operation. The problems of preoperative diagnosis are mentioned, also rate and early complications of spontaneous bilio-digestive fistulae and their poor prognosis concerning the increased letality at operation.
