虚拟现实技术在微创外科实习中的应用是可行的，有利于提高实习医师微创外科的操作水平。对外科实习生压力应对的研究表明，软技能对外科课程中VR表现的额外影响。本研究的目的是评估结构化虚拟现实训练和软技能对受训者虚拟现实表现的影响，研究设计为单中心随机对照试验。50名MIS经验有限的第一年外科住院医师（仅腹腔镜胆囊切除术中的“摄像机导航”）被随机分配接受3个月的VR培训或不接受培训。在随机化之前，使用VR模拟器LapSim（A（R））的基本模块和标准化心理问卷对基本VR表现和定义的软技能（自我效能、压力应对和动机）进行评估。随机化后3个月，重新评估VR性能。结果测量是基于最复杂的基本VR模块（“透热切割”）作为主要终点的结果。对两组的VR终点表现与心理评分进行相关分析，结构化VR训练提高了外科实习生的VR表现。高动机状态与VR成绩相关（P < 0.05），低自我效能感和消极应对与VR成绩相关（P < 0.05）。低自我效能感和消极的压力应对策略似乎预示着不良的VR表现。然而，结构化的训练沿着高动机状态可能会抵消这种损害。
Virtual reality (VR) training in minimal invasive surgery (MIS) is feasible in surgical residency and beneficial for the performance of MIS by surgical trainees. Research on stress-coping of surgical trainees indicates the additional impact of soft skills on VR performance in the surgical curriculum. The aim of this study was to evaluate the impact of structured VR training and soft skills on VR performance of trainees.The study was designed as a single-center randomized controlled trial. Fifty first-year surgical residents with limited experience in MIS ("camera navigation" in laparoscopic cholecystectomy only) were randomized for either 3 months of VR training or no training. Basic VR performance and defined soft skills (self-efficacy, stress-coping, and motivation) were assessed prior to randomization using basic modules of the VR simulator LapSim(A (R)) and standardized psychological questionnaires. Three months after randomization VR performance was reassessed. Outcome measurement was based on the results derived from the most complex of the basic VR modules ("diathermy cutting") as the primary end point. A correlation analysis of the VR end-point performance and the psychological scores was done in both groups.Structured VR training enhanced VR performance of surgical trainees. An additional correlation to high motivational states (P < 0.05) was found. Low levels of self-efficacy and negative stress-coping were related to poor VR performance in the untrained control group (P < 0.05). This correlation was absent in the trained intervention group (P > 0.05).Low self-efficacy and negative stress-coping strategies seem to predict poor VR performance. However, structured training along with high motivational states is likely to balance out this impairment.
