Application of mixed reality technology in patients with early non-small cell lung cancer
Objective To explore the applied value of mixed reality(MR)technology in thoraco-scopic precision lung segmentectomy in early-stage non-small cell lung cancer(NSCLC).Methods The clinical data of 70 patients with early-stage NSCLC admitted to Tianjin Chest Hospital were retrospectively an-alyzed.According to the different treatment modes,the patients were divided into the MR group(30 cases,based on thoracoscopic precision segmental lung resection with MR technology to assist doctor-patient com-munication,preoperative planning and surgical guidance)and the control group(40 cases,with classic thoracoscopic precision segmental lung resection alone).The effectiveness of doctor-patient communica-tion,surgical indexes,pre-and post-surgical pulmonary function and perioperative complications were com-pared between the two groups.SPSS 26.0 statistical software was used,Independent sample t test was used for comparison between groups.Results The MR group had a higher surgical knowledge score[(93.20±2.49)points vs.(90.89±3.26)points,t=3.235,P＜0.05]and surgical conversation satisfaction score[(94.28±2.36)points vs.(91.32±3.04)points,t=4.424,P＜0.05]than the control group,and the selfrating anxiety scale(SAS)score in the MR group[(31.45±3.39)points vs.(33.89±2.15)points,t=3.676,P＜0.05]was lower than in the control group.In the MR group,the operation time[(151.18±28.27)min vs.(125.56±26.63)min,t=3.864,P＜0.05],drain removal time[(4.15±1.74)d vs.(6.05±1.37)d,t=5.113,P＜0.05],and postoperative hospital stay[(6.48±2.23)d vs.(8.20±2.19)d,t=3.227,P＜0.05]were shorter than in the control group,and intraoperative haemorrhage[(90.46±10.25)ml vs.(126.67±10.39)ml,t=14.513,P＜0.05],postoperative drainage[(352.41±45.59)ml vs.(404.46±42.27)ml,t=4.930,P＜0.05]in the MR group were less than in the control group.Postoperative maximum voluntary ventilation(MVV)[(90.74±8.23)L vs.(97.15±2.24)L]in the MR group,and(85.38±7.52)L vs.(97.86±2.15)L in the control group(t=2.263,2.586,P＜0.05),forced expiratory volume at one second(FEV1)[MR group(1.95±0.38)Lvs.(2.23±0.69)L;control group(1.74±0.40)L vs.(2.30±0.71)L,t=2.223,2.149,P＜0.05],forced vital capacity(FVC)[MR group(2.78±0.36)Lvs.(3.05±0.33)L;control group(2.52±0.40)Lvs.(3.11±0.29)L,t=2.814,2.748,P＜0.05]were lower than preoperatiion,but higher in the MR group than in the control group.There was no statistically significant difference in the rate of perioperative complications between two groups[13.33％(4/30)vs.20.00％(8/20),x2=0.536,P＞0.05].Conclusion MR technology has demonstrated its advantages of improved communication and surgical efficiency,reduced lung function impairment,and low complication rates in thoracoscopic preci-sion segmental lung resection in early-stage NSCLC,and it is expected to become a standard adjunct when it matures and costs are reduced.
