Background: Bronchogenic cysts are benign congenital malformations of the primitive ventral foregut. The aim of this study is to analyze and report 20 years of experience in the diagnosis and treatment of bronchogenic cysts at a tertiary pediatric center.
Methods: A retrospective review was conducted of all patients diagnosed with a bronchogenic cyst between 2000-2020. Presence of symptoms, cyst location, surgical technique, postoperative complications, need for pleural drainage, and recurrence were reviewed.
Results: Forty-five children were included in the study. In 37 patients a partial resection of the cyst was done, followed by cauterization or chemical obliterateration with iodopovidone of the mucosa of the remaining cyst wall that was adherent to the airway. A lobectomy was done in patients who had intrapulmonary cysts (n = 8). Cyst location was subcarinal in 23 (51.1%), paratracheal in 14 (31.1%), and intrapulmonary in eight patients (17.8%). The majority of subcarinal and paratracheal cysts (90%) were approached by thoracoscopy. Complications occurred in seven patients (15%): subcutaneous emphysema after pleural drain removal in one, extubation failure in two, reoperation due to bleeding in one, surgical site infection in one, bronchopleural fistula in one, and pneumothorax in one. Reoperation due to cyst recurrence was necessary in two patients (4.4%). Mean follow-up was 56 months (range, 0-115).
Conclusion: A minimally invasive approach is a safe option for the management of paratracheal and subcarinal bronchogenic cysts with no history of infection in specialized pediatric surgery center. Thoracoscopic partial resection is a feasible option in most patients with subcarinal and paratracheal bronchogenic cysts with a low complication and reoperation rate.
Level of evidence: IV.
