BACKGROUND: Post-esophagectomy tracheo-bronchial-esophageal fistula (PETEF) most often develops after anastomotic disruption or gastric conduit necrosis. Ideal surgical management and outcomes for this complication are uncertain. METHODS: A retrospective review of 11 patients undergoing surgical repair of PETEF was performed. RESULTS: The median time between esophagectomy and surgical repair of PETEF was 61 days (range, 7 days to 28 years). Anastomotic leak or gastric conduit necrosis was responsible for PETEF in 6 patients (54.5%), whereas other causes were erosion of a tracheal appliance (n = 2), gastric conduit staple line erosion (n = 1), anastomotic stricture dilation (n = 1), and recurrent esophageal cancer (n = 1). Membranous airway defects were repaired primarily and buttressed with muscle or omental flaps in 8 patients (72.7%), whereas two (18.2%) were repaired with bio-prosthetic patches and one (9.1%) was repaired with a sleeve resection of the bronchus. Anastomotic and neo-esophageal conduit defects were repaired primarily in 3 patients (27.3%), whereas 7 patients (63.6%) underwent conduit take-down and esophageal or pharyngeal diversion, and 1 patient (9.1%) underwent simultaneous fistula repair and colon interposition. Two patients (18.2%) had recurrent fistulas, with 1 patient dying after second fistula closure and the other was discharged with no further attempt at repair. Three patients (27.3%) died postoperatively. Only 3 patients (27.3%) resumed an oral diet after fistula repair. CONCLUSIONS: Surgical treatment is effective for most patients undergoing operative repair of PETEF, notwithstanding a considerable risk of postoperative morbidity and death. Although fistula repair is life saving and prevents further respiratory deterioration, return to oral alimentation is not ensured.
