The aim of this study was to evaluate the outcomes of video-assisted thoracic surgery (VATS) for mediastinal bronchogenic cyst (MBC) excision and investigate the surgical indication for MBC.


We retrospectively reviewed all consecutive MBC patients who underwent surgical excision between April 2001 and June 2016. One hundred and nineteen patients were enrolled with a median age of 45.4 years and divided into two groups: anterior mediastinum group (n = 48), and middle and posterior mediastinum group (n = 71). VATS technique was initially performed for each patient. The cyst should be resected completely as far as possible. Follow-up was completed by telephone or outpatient clinic every year. The deadline of follow-up was June 2017.


One hundred and eighteen patients underwent VATS, and only one patient converted to open thoracotomy. The average operative time was 103.8 ± 41.6 min (40–360 min). The average intraoperative blood loss was 56.6 ± 86.6 ml (5–600 ml). The intraoperative complication rate was 3.4%, and the incomplete excision rate was 5.9%. The multivariate logistic analysis showed that maximal diameter >5 cm was significantly associated with risk of operation time extension (OR = 3.968; 95% CI 1.179–13.355, p = 0.026) and bleeding loss increasing (OR = 12.242; 95% CI 2.420–61.933, p = 0.002). No serious postoperative complications were observed. Follow-up was performed in 102 patients, and the mean follow-up time was 45 months (12–194 months). There was no local recurrence.


The maximal diameter >5 cm increased risk of operation time extension and bleeding loss increasing. Early surgical excision of MBC by VATS is recommended to establish histopathological diagnosis, relieve symptoms, and prevent surgery-related complications.
