Postoperative Recurrences of Pneumothorax in Video-assisted Thoracoscopic Surgery for Primary Spontaneous Pneumothorax in Young Patients

Purpose: The postoperative recurrence rate of pneumothorax tends to be higher with thoracoscopic bullectomy than with conventional plication of bullae by axillary thoracotomy or posterolateral thoracotomy. We analyzed the risk factors for postoperative recurrence of pneumothorax in young patients treated with thoracoscopic bullectomy alone for primary spontaneous pneumothorax. Methods: Univariate and multivariate analyses were performed of a consecutive series of 53 patients (62 sides) who underwent video-assisted thoracoscopic bullectomy from March 1994 through March 2004. Results: Pneumothorax recurred after 10 operations (16.1%). Eighty percent of postoperative pneumothorax recurrences developed within 5 months after surgery. Univariate analysis of postoperative pneumothorax recurrences revealed significant risk factors to be the early period of video-assisted thoracoscopic surgery (VATS) experience for primary spontaneous pneumothorax and a low number of pack-years (p
