[Benign esophageal-respiratory fistulae. The surgical treatment and results of 10 cases].

Benign esophago-respiratory fistula is a relatively rare condition of great surgical interest because of its potential total curability. The ratio of benign to malignant fistula is around 1:5. Sometimes the diagnosis is difficult because of the non specific nature of presenting symptoms. This report concern 10 cases of benign esophagorespiratory fistulas observed during a period of twenty years. There were 6 esophago-tracheal fistulas and 4 esophagobronchial fistulas. In 4 cases the fistulas were congenital, in 1 the fistula was due to perforation of esophageal diverticulum and in 3 patient the fistula developed after prolonged intubation. All patient underwent surgical treatment consisted of division of the fistula and suture of both esophageal and respiratory defect. In 4 cases we performed pulmonary parenchyma resection because of irreversible inflammatory lesions. There were no perioperative death. One young patients with tubercular fistula developed a dehiscence of esophageal suture successfully treated with pleural drainage and several application of fibrin glue. All patient were considered to have very good results.
