Our goal was to evaluate the changes in lung function and exercise capacity following pulmonary resection in these patients; we also looked for outcome predictors.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>METHODS<\/jats:title>\n                  <jats:p>We performed a non-randomized prospective study evaluating lung function changes in patients with non-cystic fibrosis bronchiectasis treated with pulmonary resection. Patients performed lung function tests and cardiopulmonary exercise tests preoperatively and 3 and 9\u2009months after the operation. Demographic data, comorbidities, surgical data and complications were collected.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>Forty-four patients were evaluated for lung function. After resection, the patients had slightly lower values for spirometry: forced expiratory volume in 1\u2009s preoperatively: 2.21\u2009l\u2009\u00b1\u20090.8; at 3\u2009months: 1.9\u2009l\u2009\u00b1\u20090.8 and at 9\u2009months: 2.0\u2009l\u2009\u00b1\u20090.8, but the relationship between the forced expiratory volume in 1 s and the forced vital capacity remained. The gas diffusion measured by diffusing capacity for carbon monoxide did not change: preoperative value: 23.2\u2009ml\/min\/mmHg \u00b1 7.4; at 3\u2009months: 21.5\u2009ml\/min\/mmHg \u00b1 5.6; and at 9\u2009months: 21.7\u2009ml\/min\/mmHg \u00b1 8.2. The performance of general exercise did not change; peak oxygen consumption preoperatively was 20.9\u2009ml\/kg\/min \u00b1 7.4; at 3\u2009months: 19.3\u2009ml\/kg\/min \u00b1 6.4; and at 9\u2009months: 20.2\u2009ml\/kg\/min \u00b1 8.0. Forty-six patients were included for analysis of complications. We had 13 complications with 2 deaths. To test the capacity of the predicted postoperative (PPO) values to forecast complications, we performed several multivariate and univariate analyses; none of them was a significant predictor of complications. When we analysed other variables, only bronchoalveolar lavage with positive culture was significant for postoperative complications (P\u2009=\u20090.0023). Patients who had a pneumonectomy had a longer stay in the intensive care unit (P\u2009=\u20090.0348).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>The calculated PPO forced expiratory volume in 1 s had an excellent correlation with the measurements at 3 and 9\u2009months; but the calculated PPO capacity for carbon monoxide and the PPO peak oxygen consumption slightly underestimated the 3- and 9-month values. However, none of them was a predictor for complications. Better tools to predict postoperative complications for patients with bronchiectasis who are candidates for lung resection are needed.<\/jats:p>\n               <\/jats:sec>\n
