[Spontaneous biliodigestive fistula].

A retrospective study was made of 23 cases of spontaneous biliodigestive fistulae collected from bile tract surgery performed in our center from 1979 to 1987, representing 1.05% of the total number of cases. The etiology was cholelithiasis in almost all cases and the most frequent connection was to the duodenum. Forty-eight percent of the cases presented as biliary ileus. In each case surgery depended on the etiology, clinical manifestations and status of the patient. The mortality was 8.7% and the morbidity 52%. Results are analyzed and a bibliographic review of the topic is offered.
