〔Abstract〕 50 patients with early non-small cell lung cancer(NSCLC) who underwent uniportal thoracoscopic segmentectomy and lobectomy were prospectively analyzed. The postoperative hospital stay, postoperative drainage and postoperative catheterization time in the segmentectomy group were lower than those in the lobectomy group, and the difference was statistically significant(P<0.05). One month and three months after operation, the forced vital capacity(FVC) and forced expiratory volumeinone second(FEVl) of the segmentectomy group were higher than those of the lobectomy group, and the difference was statistically significant(P<0.05). For the treatment of early NSCLC, the curative effect of uniportal thoracoscopic segmentectomy is equal to or even better than that of uniportal thoracoscopic lobectomy. In addition, uniportal thoracoscopic segmentectomy has less effect on patients′ pulmonary function and makes patients recovery more quickly.
