BACKGROUND: Recurrence of pneumothorax after thoracoscopic surgery is a concerning issue for thoracic surgeons. In this study, we aimed to determine the risk factors for recurrence of spontaneous pneumothorax after thoracoscopic surgery. METHODS: A total of 192 patients with spontaneous pneumothorax aged <50 years who underwent thoracoscopic surgery from January 2010 to December 2016 were included in this study. Pre- and post-operative characteristics were obtained from medical records, and recurrent and non-recurrent cases were compared. RESULTS: Fourteen patients (7.3%) experienced pneumothorax recurrence. Pneumothorax recurrence was observed more frequently in patients aged <20 years (P=0.041) and those in whom bullae were not identified on preoperative computed tomography (CT) (P=0.049). The use of polyglycolic acid (PGA) sheets during surgery significantly decreased the recurrence rate (P=0.031). A history of ipsilateral pneumothorax before surgery was a significant risk factor for recurrence after thoracoscopic surgery (P=0.001). In the multivariate analysis, a history of ipsilateral pneumothorax and identification of bullae on CT were identified as significant risk factors for recurrence. CONCLUSIONS: A history of ipsilateral pneumothorax, and inability to identify bullae on preoperative CT were risk factors for postoperative recurrence of pneumothorax.
