[ Pleural tent after upper lobectomy -- randomized study of it 's efficacy and duration of the effect ] . UNLABELLED The aim of our study is to evaluate the safety , efficacy and also the maximum duration of effect of the pleural tent in reducing the incidence of air leak after upper lobectomy . METHODS Sixty patients who underwent upper lobectomy were prospectively randomized into two groups : 30 patients had creation of pleural tent ( group 1 ) and 30 did not ( group 2 ) . The preoperative , operative , and postoperative characteristics of both groups were compared . Then multivariate analyses were used to identify factors predictive of prolonged air leaks and their duration . The reduction of incidences of air leak in the two groups was subsequently compared during successive postoperative periods . RESULTS Demographic and clinical profiles of both groups were not statistically different . The tented patients had statistically significant reduction of mean duration of air leak in days ( 4.9 +/- 1.79 vs 8.2 +/- 4.2 ) , the number of days of a chest tube duration ( 7.3 +/- 1.14 vs 12.46 +/- 3.6 ) , the length of postoperative in-hospital stay in days ( 9.4 +/- 1.86 vs 13.6 +/- 2.49 ) , and the hospital stay cost per patient ( leva , 3840 +/- 298 vs 5160 +/- 3890 ) . Logistic regression analyses showed that no having creation a pleural tent procedure was the most significant predictive factor of the occurrence and duration of prolonged air leaks . A greater reduction in the duration of air leaks was observed before postoperative day 4 in group 1 , and logistic regression analysis showed that having a pleural tent procedure was the most significant predictive factor of air leaks that persisted for less than 4 days . CONCLUSIONS Pleural tent creation after upper lobectomy is a simple and safe procedure that reduces the duration of air leaks and the hospital stay costs . The benefit from that procedure is achieved before postoperative day 4 .
