Tracheo Esophageal Fistula Repair

Repairing a complex tracheoesophageal fistula (TEF) through a sternotomy involves advanced techniques designed to provide wide exposure, safe control of the airway, and durable separation of the trachea and esophagus. After median sternotomy and mobilization of the great vessels, the trachea is circumferentially exposed above and below the fistula while maintaining strict airway stabilization, often with distal tracheal intubation or extracorporeal support in high-risk cases. The esophagus is carefully dissected posteriorly to avoid devascularization, and the fistula tract is divided with meticulous preservation of surrounding structures such as the recurrent laryngeal nerves. Definitive repair typically includes tension-free primary closure of both the tracheal and esophageal defects, reinforced with a well-vascularized interposition flap—commonly a thymic, pericardial, strap-muscle, or omental flap delivered through the sternotomy - to prevent recurrence. Advanced adjuncts include intraoperative bronchoscopic guidance, use of biologic buttressing materials, and placement of temporary airway stents in fragile tracheal segments. This approach provides exceptional exposure for complex or recurrent TEFs, especially those associated with previous surgery, malignancy, prolonged ventilation, or mediastinal inflammation.
