Summary: Methods: This retrospective cohort study identified patients who underwent video-assisted thoracic surgery (VATS) lobectomy for lung cancer from January 2016 to December 2018 in a Chinese tertiary general hospital. The electronic hospital medical records associated with the VATS lobectomy for lung cancer were the data sources. Results: Based on the analysis of 433 patients with the utilization of staplers in their VATS lobectomy for lung cancer, using powered stapler was associated with significantly shorter operation time and postsurgery hospital stay length than using the manual stapler in the multivariable generalized linear regression analyses with the adjustment of patient characteristics. However, no other significant differences were observed for other clinical outcomes between the two staplers.

概述：
方法：本回顾性队列研究选取2016年1月至2018年12月期间，国内某三级综合医院收治的接受肺癌胸腔镜手术（video-assisted thoracic surgery, VATS）肺叶切除术的患者，数据来源为此类手术患者的医院电子病历。
结果：对433例在肺癌VATS肺叶切除术中使用吻合器的患者进行分析后，在校正患者基线特征的多变量广义线性回归分析中，使用电动吻合器的患者手术时长与术后住院时长均显著短于使用手动吻合器的患者；但两种吻合器在其余临床结局指标上未观察到显著差异。
