Abstract	BackgroundAtelectasis of the middle lobe after right upper lobectomy is often seen. However, the risk factors for atelectasis are uncertain. Therefore, we assessed cases in our institution and investigated risk factors for atelectasis of the middle lobe following right upper lobectomy.MethodsWe identified 354 cases in which right upper lobectomy had been performed in our institution between January 2009 and December 2018, and 342 were included in this retrospective analysis. We divided patients into two groups according to the presence of postoperative atelectasis of the middle lobe, and then preoperative clinical variables and perioperative variables were compared between the two groups. Multivariable analyses for postoperative atelectasis of the middle lobe were performed using the logistic regression model.ResultsMiddle lobe atelectasis was detected in 59 cases (17.3%). Multivariable analysis demonstrated that the preoperative diameter of the middle lobe bronchus [P=0.012; confidence interval (CI), 0.525–0.930] and stapling of the fissure between the upper and middle lobes (P=0.004; CI, 1.997–37.050) were independent risk factors for postoperative atelectasis of the middle lobe.ConclusionsA small preoperative diameter of the middle lobe bronchus and stapling of the fissure between the upper and middle lobes are risk factors for middle lobe atelectasis following right upper lobectomy.
