Objective:To explore curative effect and learning curve of single-port da Vinci robot-assisted radical resection for lung cancer on lung function.Methods:A retrospective cohort study was conducted to select 120 patients with lung cancer who admitted to the Affiliated Cancer Hospital of Xinjiang Medical University from June 2023 to April 2024.According to different treatment methods,they were divided into an observation group and a control group,with 60 cases in each group.The control group adopted thoracoscopic surgery to conduct treatment,while the observation group adopted single-port da Vinci robot-assisted radical resection to treat lung cancer.The differences of surgical indicators,treatment outcomes,postoperative complications,and fitting of learning curve were compared between the two groups.Results:There were not statistically significant differences in total postoperative drainage volume of chest,duration with tube between the observation group and the control group(P﹥0.05).The conversion rates to conduct laparotomy were respectively 1.67％(1/60)and 11.67％(7/60)in the observation group and the control group,with a statistically significant difference between the two groups(x2=4.821,P<0.05).The operational time,the volume of intraoperative blood loss,and postoperative length of hospital stay of observation group were all shorter than those of control group,and all differences were statistically significant(t=13.318,93.763,3.797,P<0.05).The total number of resecting lymph nodes,the number of resecting lymph nodes of N2 station,and total number of the groups of resecting lymph nodes of observation group were all higher than those of control group,and the differences were statistically significant(t=2.960,3.048,6.319,P<0.05).There were not statistically significant differences in postoperative complications,which included pulmonary leakage,pleural effusion,and incision bleeding after surgery,between observation and control groups(P﹥0.05).The surgical time of observation group of using single-port da Vinci robot-assisted radical resection for lung cancer was shortest when the surgical case was the 55th case(101.22 min),and the fitting of learning curve was favorable(R2=0.912).Conclusion:Using single-port da Vinci robot-assisted radical resection for lung cancer to treat patients with lung cancer,the resected lymph nodes and postoperative bleeding of patients are significantly improved.The learning curve of single-port da Vinci robot-assisted radical resection for lung cancer was short.After the 55th surgery,the operation is gradually proficient,and the surgical time gradually trends to stable stage.It can be used as one of clinically important measures.
