Gastric bypass for malignant esophagotracheal fistula: a series of 21 cases.

OBJECTIVE Patients with cancer of the esophagus who develop an esophagotracheal fistula die within 1 month in dramatic conditions of malnutrition and asphyxia. We assessed the beneficial palliative effect of the Kirschner operation in the treatment of esophagotracheal fistula. METHODS Between January 1980 and August 1995, 21 patients among a continuous series of 847 with cancer of the esophagus developed an esophagotracheal fistula. Prior to surgery, 2 patients had an esophageal prosthesis followed by radio- and/or radiochemotherapy and 6 had radio- and/or chemotherapy at curative doses. The Kirschner operation was carried out in all patients with exclusion of the lower end of the esophagus using a Roux-en Y-loop (n = 19) or ligature (n = 2). RESULTS Within 1 month of surgery, 8 patients (38%) died. Median length of stay in the intensive care unit and hospitalization was 6 days (1-30) and 17 days (3-57), respectively. Among the 13 survivors, pulmonary infections (n = 2) and cervical fistulae (n = 5) complicated the postoperative period. Among the cervical fistula, 3 of them resolved favorably. Radio- and/or chemotherapy was given postoperatively in 7 patients without any improvement in survival. Among the 13 patients surviving beyond the postoperative period, median survival was 109 days; 7 were able to resume oral nutrition and quality of life was assessed as excellent in 6 of them. CONCLUSION The Kirschner operation can provide a beneficial palliative effect in patients with an esophagotracheal fistula despite the high risk of operative mortality. Ideally, the Kirschner should be carried out in young patients who are still in good general health, before the development of respiratory complications compromises surgery.
