Surgical treatment of benign tracheo-oesophageal fistulas with tracheal resection and oesophageal primary closure: is the muscle flap really necessary?☆

Objectives: Nowadays, despite the advances of the low-pressure high-volume cuffs, post-intubation tracheo-oesophageal fistula (TEF) still poses a major challenge to thoracic surgeons. The original technique includes interposition of muscle flaps between suture tines to avoid recurrence. It is not clear if this manoeuvre is indispensable and, in fact, we and others have faced problems with it. Our aim is to present our experience with TEF management in a consecutive group with no muscle interposition. Methods: From June 1992 to November 2007, we evaluated 14 patients presenting with TEE with a mean age of 44years (from 18 to 79 years). Thirteen patients had a prolonged intubation history. The remaining case was a 40-year-old mate with congenital TEE Three patients had been previously submitted to failed repairs in other institutions. Ten patients had associated tracheal stenosis, which was subglottic in three of them. Regarding surgical technique, in all cases, we performed a single-staged procedure, which consisted of tracheal resection and anastomosis with double-layer oesophageal closure. In none of our cases was a muscle flap interposed between suture tines. Results: All operations were performed through a cervical incision; however, in one case, an extension with partial sternotomy was required. There was no operative mortality. Thirteen patients were extubated in the first 24 h after the procedure, white one patient required 48 h of mechanical ventilation. Four complications were recorded: one each of pneumonia and left vocal cord paralysis and two small tracheal dehiscences managed with a T-tube and a tracheostomy tube. After discharge, three patients returned to their native cities and were lost to follow-up. The remaining 11 patients have been followed up by a mean of 32 months (from three to 108 months), with 10 presenting excellent and one good anatomic and functional results. Conclusions: The single-staged repair with tracheal resection and anastomosis with oesophageal closure provides good short- and mid-term results for TEF management. The interposition of a muscle flap between suture tines may not be crucial to prevent recurrence. (C) 2009 European Association for Cardio-Thoracic Surgery. Published by Elsevier B.V.
