Single-port video-assisted thoracic surgery versus three-port video-assisted thoracic surgery for primary spontaneous pneumothorax

Abstract

Objective To explore the effects of single-port video-assisted thoracic surgery versus three-port videoassisted thoracic surgery for primary spontaneous pneumothorax. Methods Video-assisted thoracic surgery was performed for primary spontaneous pneumothorax in 58 patients from April 2012 to April 2013. We reviewed the medical records of these 58 patients, retrospectively. Thirty patients underwent the three-port video-assisted thoracic surgery (three-port group) and 28 patients underwent the single-port video-assisted thoracic surgery (single-port group). Following the operation, clinical outcomes, complications and overall survival were evaluated. Results There was no difference in patient characteristics between two groups. Compared with three-port video-assisted thoracic surgery, single-port video-assisted thoracic surgery had shorter hospital stay, shorter chest tube drainage, lower visual analog scale score score of 6 h postoperative pain and visual analog scale score score of 24 h postoperative pain. Meanwhile, there were no statistical differences between both groups in intraoperative bleeding, overall survival and progression-free survival. Conclusions Single-port video-assisted thoracic surgery can reduce the postoperative pain and get better clinical outcomes in treatment of primary spontaneous pneumothorax.
