Application of virtual reality technology in thoracoscopic anatomical segmentectomy / 中国基层医药

ABSTRACT

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 ( t=-2.208, -3.328, 5.916, 4.678, -4.221, -3.993, -3.265, -3.968, χ 2=3.977, all P<0.05). No local recurrence or distant metastasis was found during the follow-up period. 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.
