| 目的 通过分析郑州大学附属郑州中心医院参加过腹腔镜技能培训的普外科青年医师的腹腔镜胆囊切除术学习曲线，探讨腹腔镜虚拟现实模拟培训的意义。方法 将青年外科医师50人分为两组，干预组参加虚拟现实模拟培训，对照组参加传统腹腔镜临床培训。培训完成后，在高年资拥有丰富腹腔镜手术经验医师的监督下完成30例腹腔镜胆囊切除术。应用CUSUM分析法，根据完成率、手术评分和手术时间绘制学员的手术学习曲线。x为手术例数，k为斜率。计算k=0时的x值，比较两组学员的手术学习曲线和术中评分。采用SPSS 23.00进行t检验和卡方检验。结果 干预组与对照组分别在x=19.24±0.39、x=21.72±0.73时跨过手术学习曲线，差异有统计学意义（P<0.01）；干预组与对照组显露胆囊部分得分分别为（10.82±2.73）、（9.71±2.69）（t=4.61，P<0.01）；解剖胆囊三角得分分别为（12.59±3.12）、（8.87±2.99）（t=6.21，P<0.01）；剥离胆囊得分分别为（10.69±3.38）、（8.80±3.55）（t=3.10，P<0.01）。结论 虚拟现实模拟培训可以促进腹腔镜培训的基本技能转化为临床操作技能，可促进普外科青年医师成长。 |

| Objective To explore the significance of laparoscopic virtual reality simulation training by analyzing the learning curve of laparoscopic cholecystectomy among young general surgeons who had participated in laparoscopic skills training at our hospital.Methods Fifty young surgeons were divided into two groups, with the intervention group participating in virtual reality simulation training and the control group participating in traditional laparoscopic clinical training. After completion of the training, 30 laparoscopic cholecystectomies were performed under the supervision of highly qualified surgeons with extensive laparoscopic experience. CUSUM analysis was applied to plot the trainees' surgical learning curve based on the completion rate, surgical score and operative time. "x" is the number of surgical cases and "k" is the slope. The value of x when k=0 was calculated and the surgical learning curves and intraoperative scores of the 2 groups of trainees were compared. SPSS 23.00 was performed for t-test and Chi-square test.Results The intervention and control groups crossed the surgical learning curve at x=19.24±0.39 and x=21.72±0.73 respectively, with significant differences (P<0.01); the intervention and control groups scored (10.82±2.73) and (9.71±2.69) for gallbladder exposure (t=4.61, P<0.01), (12.59±3.12) and (8.87±2.99) for gallbladder dissection triangle (t=6.21, P<0.01), and (10.69±3.38) and (8.80±3.55) for gallbladder dissection (t=3.10, P<0.01).Conclusions Virtual reality simulation training can facilitate the translation of basic laparoscopic training skills into clinical skills and can promote the growth of young general surgeons. |
