Objective:To investigate different incidences of recent complications after thoracoscopic lobectomy at different operation schedules in patients with early stage non-small cell lung cancer(NSCLC).Methods:A total of 730 patients with early stage NSCLC who underwent thoracoscopic lobectomies in the Department of Thoracic Surgery, Peking University People's Hospital from June 2013 to October 2017 were enrolled. Clinical data were collected retrospectively to calculate the incidence of postoperative complications. Meanwhile, the effects of different operation time periods(before 4pm or after 4pm, working day or weekend) on complications were compared, and the propensity score matching method was used to eliminate the confusion factors that may cause result bias. Univariate and multivariate logistic regression methods were used to analyze the independent risk factors of postoperative complications.Results:162 patients(22.2%) had complications within one month after thoracoscopic surgeries, and 53(7.3%) of them were major complications. After the propensity scores of the preoperative clinical factors were matched, there was no significant difference in the incidence of complications between weekdays and weekends(18.7% vs 23.9%, P=0.267). There was also no significant difference in the effect of complications between the group before 4pm and group after 4pm on surgery(22.1% vs 27.9%, P=0.337). Conclusion:The incidence of recent complications in patients with early stage NSCLC after thoracoscopic lobectomy was as acceptable as 22.2%. The choice of operation schedules did not affect the postoperative complications.
