目的:探讨虚拟现实技术在胸腔镜解剖性肺段切除术中的应用价值。方法:选取嘉兴市第一医院2017年12月至2018年12月收治的早期非小细胞肺癌患者84例为研究对象，采用随机数字表法分为观察组和对照组，各42例；观察组用虚拟现实技术构建三维数字化模型，并在三维数字化模型上进行术前评估及模拟手术演练和术中导航，基于术前评估及模拟手术演练的结果，并结合术中具体实际情况制定并实施个体化的胸腔镜解剖性肺段切除术。对照组常规实施胸腔镜解剖性肺段切除术。比较两组患者的手术时间、术中出血量、术中清扫淋巴结组数、术中清扫淋巴结个数、术后住院时间、术后拔除胸腔闭式引流管时间、术后总引流量、住院总费用和术后并发症发生率。结果:两组患者均顺利完成手术，术中均无中转开胸，无围术期死亡。观察组手术时间、术中出血量、术中清扫淋巴结组数、术中清扫淋巴结个数、术后住院时间、术后拔除胸腔闭式引流管时间、术后总引流量、住院总费用和术后并发症发生率分别为(100.98±26.51)min、(67.98±32.96)mL、(7.79±1.32)组、(11.98±4.69)个、(4.60±1.43)d、(2.86±0.81)d、(437.14±193.86)mL、(3.76±0.31)万元、9.52%(4/42)，对照组分别为(114.88±24.26)min、(104.52±52.37)mL、(6.45±0.30)组、(8.31±1.94)个、(6.50±2.55)d、(4.00±2.25)d、(667.26±415.01)mL、(4.20±0.65)万元、26.19%(11/42)，两组差异均有统计学意义(n t＝－2.208、－3.328、5.916、4.678、－4.221、－3.093、－3.265、－3.968，χn 2＝3.977，均n P<0.05)。两组患者随访期间均未发现局部复发、远处转移。n 结论:虚拟现实技术能为胸腔镜解剖性肺段切除术提供术前评估、模拟手术演练及术中导航，降低了手术难度，可提高手术的精确度及安全性。“,”Objective:To explore the application value of virtual reality technology in thoracoscopic anatomical segmentectomy.Methods:Eighty-four patients with early stage non-small cell lung cancer admitted to the First Hospital of Jiaxing from December 2017 to December 2018 were enrolled in the study.They were divided into observation group and control group according to the random digital table method, with 42 cases in each group.The observation group used virtual reality technology to construct a three-dimensional digital model, and performed preoperative evaluation and simulated surgical drills and intraoperative navigation on the three-dimensional digital model, based on the preoperative evaluation and simulated surgical drill results, combined with the specific actual situation during the operation, developed and implemented individualized thoracoscopic anatomical segmentectomy.Thoracoscopy anatomical segmentectomy was routinely performed in the control group.The operation time, intraoperative blood loss, intraoperative lymph node dissection number, intraoperative lymph node dissection, postoperative hospital stay, postoperative thoracic closed drainage tube, total postoperative drainage, total hospitalization, cost and incidence of postoperative complications were compared between the two groups.Results:The operation of both two groups was successfully completed, and no intraoperative thoracic surgery was performed during the operation.There was no perioperative death.The operation time, intraoperative blood loss, intraoperative lymph node dissection number, intraoperative lymph node dissection, postoperative hospital stay, postoperative thoracic closed drainage tube, total postoperative drainage, total hospitalization cost and the incidence of postoperative complications in the observation group were (100.98±26.51)min, (67.98±32.96)mL, (7.79±1.32), (11.98±4.69), (4.60±1.43)d, (2.86±0.81)d, (437.14±193.86)mL, (3.76±0.31)million, 9.52%(4/42), respectively, which in the control group were (114.88±24.26)min, (104.52±52.37)mL, (6.45±0.3), (8.31±1.94), (6.50±2.55)d, (4.00±2.25)d, (667.26±415.01)mL, (4.20±0.65)million, 26.19%(11/42), respectively, the differences between the two groups were statistically significant (n t=-2.208, -3.328, 5.916, 4.678, -4.221, -3.993, -3.265, -3.968, χ n 2=3.977, all n P<0.05). No local recurrence or distant metastasis was found during the follow-up period.n Conclusion:Virtual reality technology can provide preoperative evaluation and simulated surgical exercises and intraoperative navigation for thoracoscopic anatomical segmentectomy, which can reduce the difficulty of surgery and improve the accuracy and safety of the operation.
