【摘要】 目的：探讨三维重建及3D打印技术在精准胸腔镜肺段切除术中的应用。方法：选取2020年1月至2022年12月在我院行精准胸腔镜肺段切除术患者105例，用随机数表法分为2组，对照组(53例)和研究组(52例),对照组给予三维重建制定术前计划，研究组给予三维重建及3D打印技术制定术前计划。比较两组围术期相关指标，术前、术后3 d、术后3个月的肺功能指标，临床治疗疗效以及并发症发生情况。结果：研究组术中出血量、住院费用与对照组比较，差异均无统计学意义(P>0.05),研究组手术时间、拔管时间、住院时间明显短于对照组(P<0.05),研究组淋巴结清扫个数明显高于对照组(P<0.05),研究组术后总引流量明显低于对照组(P<0.05)。术后3 d研究组用力肺活量(FVC)、第1秒用力呼气容积(FEV1)、呼气流量峰值(PEF)、每分钟最大通气量(MVV)、肺一氧化碳弥散量(DLCO)较术前均降低(P<0.05),术后3 d、术后3个月对照组FVC、FEV1、PEF、MVV、DLCO较术前均降低(P<0.05),术后3 d对照组FEV1/FVC较术前升高(P<0.05),术后3个月对照组FEV1/FVC较术前降低(P<0.05),且术后3 d、术后3个月研究组FVC、FEV1、PEF、MVV、DLCO明显高于对照组(P<0.05),术后3个月研究组FEV1/FVC明显高于对照组(P<0.05)。研究组临床治疗疗效优于对照组，且研究组的临床治疗总有效率为94.23%,明显高于对照组(67.92%)(P<0.05)。研究组的并发症发生率为19.23%,与对照组(24.53%)比较，差异无统计学意义(P>0.05)。结论：三维重建及3D打印技术应用在精准胸腔镜肺段切除术中，可有效缩短手术时间，促进患者康复，改善肺功能，提高临床治疗疗效，且安全性较好。更多还原

【Abstract】 Objective:To explore the application of 3D reconstruction and 3D printing technology in precision thoracoscopic pulmonary segment resection.Methods:A total of 105 patients undergoing precision thoracoscopic pulmonary segmental resection in our hospital from January 2020 to December 2022 were selected and random number table method was used to divide into two groups:a control group of 53 patients and a study group of 52 patients.The control group was given 3D reconstruction to formulate a preoperative plan,while the study group was given 3D reconstruction and 3D printing technology to formulate a preoperative plan.The perioperative related indicators,lung function indicators,clinical treatment efficacy, and complications were compared between the two groups at three time points:before surgery,3 days after surgery,and 3 months after surgery.Results:There were no statistically significant differences in intraoperative bleeding and hospitalization expenses between the study group and the control group(P>0.05).The operation time,extubation time,and hospitalization time in the study group were significantly shorter(P<0.05).The number of lymph nodes dissected was significantly higher in the study group compared to the control group(P<0.05),and the total postoperative drainage flow in the study group was significantly lower than that in the control group(P<0.05).The forced vital capacity(FVC),forced expiratory volume in one second(FEV1),peak expiratory flow(PEF),maximal voluntary ventilation(MVV),and diffusion capacity of carbon monoxide of lung(DLCO) in the study group were lower than those before surgery and 3 days after surgery(P<0.05).The FVC,FEV1,PEF,MVV,and DLCO in the control group were lower than those before surgery,3 days and 3 months after surgery(P<0.05).The FEV1/FVC in the control group was higher than those before surgery and 3 days after surgery(P<0.05).The FEV1/FVC in the control group was lower than those before surgery and 3 months after surgery(P<0.05),and the FVC,FEV1,PEF,MVV,and DLCO in the study group were significantly higher than those in the control group 3 days and 3 months after surgery(P<0.05).Three months after surgery,the FEV1/FVC in the study group was significantly higher than that in the control group(P<0.05).The clinical treatment efficacy of the study group was better than the control group,and the total clinical treatment effective rate of the study group was 94.23%,significantly higher than 67.92% of the control group(P<0.05),The incidence of complications in the study group was 19.23%,which was not statistically significant compared to 24,53% in the control group(P>0.05).Conclusion:The application of 3D reconstruction and 3D printing technology in precise thoracoscopic lung segment resection effectively reduces operative time,enhances patient recovery,improves lung function,and increases the efficacy of clinical treatment with good safety.更多还原
