Preoperative variables such as age, FEV1, FVC, Tiffneau index, ppo FEV1, PaO2, partial PaCO2, hemoglobin and serum albumin levels, diabetes status, tobacco use (packet years), use of cortisol, presence and stage of COPD were evaluated by logistic regression analysis. Some intraoperative variables such as side, localization, type and volume of resection, standard or extended resections, the presence of pleural adhesions and the length of resected interlobar fissure were assessed by the same analysis, as well.ResultsProlonged air leak was wound in 14.3 % of the cases. The univariate analysis showed that FEV1, FEO1/FVC, ppo FEV1, COPD stage, tobacco and corticosteroids uses, upper lobectomies, pleural adhesions, distance of sutured fissure and extended resection cause postoperative air leak for more than 7 days. In multivariate analysis only low levels of FEO1 (p=0,004), FEO1/FVC (p=0,02), ppo FEO1 (p=0,001), COPD stage (p=0,01), pleural adhesions (p=0,0001) and long interlobar fissure resection (p=0,006) were the main risk factors for this complication.ConclusionThe risk factors of prolonged air leak after pulmonary resections should be carefully evaluated in every patient in order to reduce the percentage of this complication.
