[Spontaneous bilio-digestive fistula of lithiasic origin].

Personal experience about 11 cases of spontaneous biliary enteric fistula caused by lithiasic disease operated in the General Surgical Clinic of the University of Siena from 1969 to 1988, is reported. The epidemiology, pathogenesis, symptomatology, indications for operation and various operating techniques performed are discussed. In the gallstone intestinal obstruction, the authors prefer to resolve immediately the obstruction, deferring to a later moment the specific operation for the treatment of the biliary enteric fistula and the lithiasic disease.
