[Postoperative digestive upper fistula. Study of 37 cases]

We report a series of 37 patients with upper gastrointestinal fistulas, from a total of 90 postoperative fistulas, treated in our Department over a period of five years (1987-1991). 46% of these originated after peptic ulcer surgery. Most patients (54%) required surgical intervention mainly due to the presence of major intraabdominal sepsis, and only 12 (32.4%) had spontaneous fistula closure. Morbidity (59.4%) and mortality rates (32.4%) were high.
