title: Thoracoscopic resection of mediastinal bronchogenic cysts in adults.
abstract: OBJECTIVE
  The aim of this study was to discuss the diagnosis and determine the optimal thoracoscopic surgical treatment of mediastinal bronchogenic cysts.
  
  
  METHODS
  From May 1996 to April 2008, 13 consecutive patients with mediastinal bronchogenic cysts underwent thoracoscopic surgery at our institution. There were eight men and five women aged 16-74 years (mean age, 41.5 years).
  
  
  RESULTS
  In the majority of patients (69.2%), there were no clinical symptoms and the lesions were found incidentally by chest radiography that was performed as part of physical screening. Lesions were found in the posterior mediastinum in five patients (38.5%) and in the upper mediastinum in four (30.8%). In the histopathological examinations, ciliary epithelium was observed in 13 patients (100.0%), bronchial cartilage in 7 patients (53.8%), bronchial glands in 6 patients (46.2%), and smooth muscle in 5 patients (38.5%). No serious postoperative complications were observed. In 3 patients (23.1%), conversion to open thoracotomy was necessary due to major pleural adhesions and intraoperative vascular injury.
  
  
  CONCLUSIONS
  Thoracoscopic resection of mediastinal bronchogenic cyst is minimally invasive and has no serious postoperative complications, and should therefore be considered as the primary therapeutic option.
