OBJECTIVES Over the past two decades, video-assisted thoracoscopic blebectomy and pleurodesis have been used as a safe and reliable option for treatment of spontaneous pneumothorax. The aim of this study is to evaluate the long-term outcome of video-assisted thoracoscopic surgery (VATS) treatment of spontaneous pneumothorax in young patients, and to identify risk factors for postoperative recurrence. METHODS We retrospectively analysed the outcome of VATS treatment of spontaneous pneumothorax in our institution in 150 consecutive young patients (age ≤40 years) in the years 1997-2010. Treatment consisted of stapling blebectomy and partial parietal pleurectomy. After excluding 16 patients lost to follow-up, in 134 cases [110 men, 24 women; mean age, 25 ± 7 standard deviation years; median follow-up, 79 months (range: 36-187 months)], we evaluated postoperative complications, focusing on pneumothorax recurrence, thoracic dysaesthesia and chronic chest pain. Risk factors for postoperative pneumothorax recurrence were analysed by logistic regression. RESULTS Of 134 treated patients, 3 (2.2%) required early reoperation (2 for bleeding; 1 for persistent air leaks). Postoperative (90-day) mortality was nil. Ipsilateral pneumothorax recurred in 8 cases (6.0%) [median time of recurrence, 43 months (range: 1-71 months)]. At univariate analysis, the recurrence rate was significantly higher in women (4/24) than in men (4/110; P = 0.026) and in patients with >7-day postoperative air leaks (P = 0.021). Multivariate analysis confirmed that pneumothorax recurrence correlated independently with prolonged air leaks (P = 0.037) and with female gender (P = 0.045). Chronic chest wall dysaesthesia was reported by 13 patients (9.7%). In 3 patients, (2.2%) chronic thoracic pain (analogical score >4) was recorded, but only 1 patient required analgesics more than once a month. CONCLUSIONS VATS blebectomy and parietal pleurectomy is a safe procedure for treatment of spontaneous pneumothorax in young patients, with a 6% long-term recurrence rate in our experience. Postoperative recurrence significantly correlates with female gender and with prolonged air leakage after surgery.

Abstract

OBJECTIVES Over the past two decades, video-assisted thoracoscopic blebectomy and pleurodesis have been used as a safe and reliable option for treatment of spontaneous pneumothorax. The aim of this study is to evaluate the long-term outcome of video-assisted thoracoscopic surgery (VATS) treatment of spontaneous pneumothorax in young patients, and to identify risk factors for postoperative recurrence. METHODS We retrospectively analysed the outcome of VATS treatment of spontaneous pneumothorax in our institution in 150 consecutive young patients (age ≤40 years) in the years 1997-2010. Treatment consisted of stapling blebectomy and partial parietal pleurectomy. After excluding 16 patients lost to follow-up, in 134 cases [110 men, 24 women; mean age, 25 ± 7 standard deviation years; median follow-up, 79 months (range: 36-187 months)], we evaluated postoperative complications, focusing on pneumothorax recurrence, thoracic dysaesthesia and chronic chest pain. Risk factors for postoperative pneumothorax recurrence were analysed by logistic regression. RESULTS Of 134 treated patients, 3 (2.2%) required early reoperation (2 for bleeding; 1 for persistent air leaks). Postoperative (90-day) mortality was nil. Ipsilateral pneumothorax recurred in 8 cases (6.0%) [median time of recurrence, 43 months (range: 1-71 months)]. At univariate analysis, the recurrence rate was significantly higher in women (4/24) than in men (4/110; P = 0.026) and in patients with >7-day postoperative air leaks (P = 0.021). Multivariate analysis confirmed that pneumothorax recurrence correlated independently with prolonged air leaks (P = 0.037) and with female gender (P = 0.045).
