Surgical management of benign cervical tracheoesophageal fistulas: A single-tertiary academic institution experience

Purpose: Despite improvements of diagnosis and management, acquired benign tracheoesophageal fistulas (AB-TEFs) remain a challenging clinical problem and a life-threating condition. In the present study, we reviewed the early results and the long-term outcomes after surgical treatment of cervical AB-TEFs treated in our institution during the last 9 years. Methods: This retrospective study included patients who underwent transcervical repair of benign cervical AB-TEFs. Patients were identified from a prospectively filled electronic database which included patients' demographics, medical history, disease presentation, prior treatments, operative report, morbidity and mortality, hospital stay, postoperative results and follow-up information. Results: A total of 13 patients affected by cervical AB-TEF were treated. Most of the patients (91%) in our series were treated with a lateral cervicotomic approach with interposition of either sternocleidomastoid muscle flap (72.7%) or pectoralis major myocutaneous flap (9.1%) or infrahyoid muscle flap (9.1%). The univariate analysis of showed that the etiology and surgical technique were significantly associated with immediate postoperative outcome. Esophageal diversion was removed in all patients but 3 due to their neurological status, which was the only significant factor related to post-operative oral-intake (p =0.016). We experienced 2 (18.2%) failures of the reconstruction, which occurred in patients previously treated with chemoradiation for head and neck malignancies. None of the remaining patients (72.8%) relapsed after a long-term follow-up restoring a normal oral diet was restored. Conclusion: The lateral cervicotomic approach with sternocleidomastoid flap interposition showed its effectiveness and safety in the treatment of AB-TEFs in our single-institution experience.
