Abstract Objective: To investigate the effects of total thoracoscopic anatomic pulmonary segmentectomy on surgical parameters, lung function and drainage volume of pulmonary nodules. Methods: 84 patients with small pulmonary nodules in our hospital from February 2016 to April 2020 were prospectively selected and randomly divided into two groups according to the random number table method. Among them, the control group (42 cases) underwent total thoracoscopic lobectomy, and the study group (42 cases) underwent thoracoscopic segmentectomy. Differences in surgical indicators, lung function indicators (FEV1, FVC, FEV1/FVC) and postoperative complications were compared between the two groups. Results: There was no significant difference in intraoperative lymph node dissection between the two groups (P>0.05), but the intraoperative blood loss, drainage volume, drainage time and hospital stay in the study group were all lower than those in the control group, and the difference was statistically significant (P<0.05).Analysis of variance of repeated measures showed that before treatment, there was no significant difference in FEV1%, FVC% and MMV% between the two groups (P<0.05). After 3, 6 and 12 months of treatment, FEV1%, FVC% and MMV% in the study group were significantly higher than those in the control group (P<0.05).In addition, the total incidence of postoperative complications was 4.76% in the study group and 9.52% in the control group, with no statistically significant difference between the groups (χ2=0.718, P>0.05) . Conclusion: The overall efficacy of total thoracoscopic anatomic pulmonary segmentectomy in the treatment of pulmonary nodules is better than that of lobectomy, which can largely retain the normal lung tissue of the patients and has less impact on the pulmonary function of the patients.
