Surgical Experiences of Pediatric Cervical Bronchogenic Cysts: A Case Series of 6 Patients.

OBJECTIVES:Bronchogenic cyst is a rare congenital disease which occurs especially in the neck region. This report presents 6 cases of bronchogenic cysts and discusses the diagnosis and surgical experience of this anomaly. METHODS:A retrospective study of 6 pediatric patients with cervical bronchogenic cysts treated in our hospital during 2016 to 2019 was performed. We recorded and analyzed the clinical data of the patients, including age, symptoms, imaging findings, surgical procedure, and complications. RESULTS:All patients underwent surgical excision. The chondroid tissues were found at the base of cysts which clung to the trachea in 5 patients and completely removed by surgery without recurrence. One patient showed recurrence due to residual cartilage after the first surgery, and the second surgery was required to resect the remaining cartilage. During the surgery, the recurrent laryngeal nerve (RLN) detector was used, which confirmed that all the RLNs clung to the side wall of cysts. All cases were cured without complications. CONCLUSIONS:Although rare, bronchogenic cysts should be considered in the differential diagnosis of peritracheal masses in children. Complete resection of the bronchogenic cysts, including the cartilages at the base, is vital in preventing recurrence. The RLN must be protected during the surgery.
