In this study, we aimed to assess the efficacy and safety of surgical treatment of spontaneous pneumothorax in patients aged \u226570\u2009years.

The incidences of postoperative persistent air leaks (\u22652\u2009days) and postoperative complications (\u2265grade 3; Clavien\u2013Dindo classification) were analysed for efficacy and safety assessment, respectively.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>Median postoperative air leaks continued for 0\u2009days (range 0\u201325); 14.4% patients developed \u2265grade 3 postoperative complications. On the basis of results of multivariable analysis, it was observed that a higher PaCO2 level was significantly associated with prolonged postoperative air leaks [odds ratio (OR) 1.08, 95% confidence interval (CI) 1.00\u20131.17; P\u2009=\u20090.047]. Poorer performance status was associated with a significantly increased risk of postoperative complications, as assessed by multivariable analysis (OR 6.13, 95% CI 1.38\u201327.3; P\u2009=\u20090.017). The recurrence rate was 4.8%; mortality rate of patients was 2.9%.
