OBJECTIVE: Complete resection of the @entity50 ( @entity50 ) tract is challenging due to repeated @entity281 and inadequate procedures. We present our experiences with intraoperative endoscopic-assisted intubation or instillation of dye through the internal opening as a guide to identify the tract. MATERIALS AND METHODS: We retrospectively reviewed the charts of 73 consecutive @entity1 diagnosed with @entity50 during 1999 until 2014 from two tertiary referral centers. Demographics, clinical presentation, imaging, treatment, and outcome were analyzed. RESULTS: The intraoperative endoscopy was successfully conducted in all 73 cases. No gender predominance was observed. Of the anomalies, 94.5% were left-sided. Presenting symptoms consisted of neck abscess (n   =   48), @entity8963 /thyroid abscess (n   =   9), neck mass with or without @entity1353 (n   =   12), and thyroid nodule (n   =   4). Barium esophagography and computed tomography scan with oral or intravenous contrast had a satisfactory positive predictive value. Partial thyroidectomy was performed on 25 cases (34.2%) if the ipsilateral thyroid was involved. Good outcome was achieved in all but 3 @entity1 (70/73, 95.9%) during a median follow-up of 4 years (range, 8 months-14 years). Two @entity1 developed @entity260 : temporary vocal fold motion @entity73 , respectively. @entity50 recurred in 1 case. CONCLUSIONS: A complete resection is essential for good outcomes. Intraoperative intubation or @entity6693 injection by endoscopy can simplify the identification of the fistula tract during surgical exploration.
