Abstract: Objective  To explore the efficacy of 3D thoracoscopic lobectomy in the treatment of primary lung cancer.
Methods  A total of 120 cases of primary lung cancer admitted to our hospital from October 2018 to February 2020 were selected.According to different surgical methods,they were divided into observation group(67 cases) and control group(53 cases).The observation group was treated with 3D t,,horacoscopic lobectomy,and the control group was treated with 2D thoracoscopic lobectomy.The operation status,number of lymph node dissection,postoperative surgical pathological stage,lung function index,pain status,and complications were recorded in the two groups.
Results  The operation time,postoperative drainage tube indwelling time,and postoperative hospital stay in the observation group were shorter than those in the control group,and the intraoperative blood loss and the 24h postoperative drainage were lower than those in the control group(P＜0.05).There was no significant difference in the number of lymph node dissection and postoperative surgical pathological staging between the two groups(P>0.05).The forced expiratory vital capacity in 1 second(FEV1) in the observation group was better than that in the control group 3 months after operation(P＜0.05).The visual analog score(VAS) of the observation group was lower than that of the control group 3 months after operation(P＜0.05).The complication rate of the observation group was significantly lower than that of the control group(5.97% vs.18.87%,P＜0.05).
Conclusion  3D thoracoscopic lobectomy for primary lung cancer can shorten the operation time,postoperative drainage tube indwelling time,postoperative hospital stays,reduce intraoperative blood loss,24h postoperative drainage,improve lung function,reduce pain,and with less complications.
