    Abstract:
    Background: Bronchogenic cysts result from a congenital anomalous budding of the tracheobronchial tree. Resection is usually recommended to avoid complications. Mediastinal bronchogenic cysts present a unique challenge due to their proximity to vital structures. The purpose of this study is to review our experience with mediastinal bronchogenic cysts. Methods: A single-institution retrospective review evaluated all mediastinal bronchogenic cyst excisions between January 2012 and November 2022. Patient demographics were assessed, including age at diagnosis, presenting symptoms, imaging workup, and cyst characteristics. Operative approach, complications, and surgical pathology were reported. Results: Five patients were identified. Age at diagnosis ranged from 18 to 27 months. No patient was diagnosed prenatally. All patients had symptoms at the time of diagnosis, including cough, wheezing, and respiratory distress. Three cysts were paratracheal, and two were paraesophageal. Age at surgery ranged from 26 to 30 months. All bronchogenic cysts were successfully resected thoracoscopically. Individual technical challenges included narrowing of the mainstem bronchus preventing lung isolation, significant mediastinal inflammation, the necessity for cyst evacuation to delineate the extent of the cyst, adherence of cyst wall to bronchus or trachea requiring cold dissection, and a stalk of tissue with an intimate connection to the carina that was amputated. No intraoperative or postoperative complication occurred. Surgical pathology was consistent with a bronchogenic cyst in all cases. Median length of hospital stay was two days. Conclusion: Thoracoscopy is a safe and effective procedure for mediastinal bronchogenic cyst excision in children. Certain technical maneuvers are highlighted, which may facilitate resection.
