OBJECTIVE
To investigate the value of laparoscopic virtual reality simulator in laparoscopic suture ability training of catechumen.
METHODS
After finishing the virtual reality training of basic laparoscopic skills, 26 catechumen were divided randomly into 2 groups, one group undertook advanced laparoscopic skill (suture technique) training with laparoscopic virtual reality simulator (virtual group), another used laparoscopic box trainer (box group). Using our homemade simulations, before grouping and after training, every trainee performed nephropyeloureterostomy under laparoscopy, the running time, anastomosis quality and proficiency were recorded and assessed.
RESULTS
For virtual group, the running time, anastomosis quality and proficiency scores before grouping were (98 ± 11) minutes, 3.20 ± 0.41, 3.47 ± 0.64, respectively, after training were (53 ± 8) minutes, 6.87 ± 0.74, 6.33 ± 0.82, respectively, all the differences were statistically significant (all P < 0.01). In box group, before grouping were (98 ± 10) minutes, 3.17 ± 0.39, 3.42 ± 0.67, respectively, after training were (52 ± 9) minutes, 6.08 ± 0.90, 6.33 ± 0.78, respectively, all the differences also were statistically significant (all P < 0.01). After training, the running time and proficiency scores of virtual group were similar to box group (all P > 0.05), however, anstomosis quality scores in virtual group were higher than in box group (P = 0.02).
CONCLUSION
The laparoscopic virtual reality simulator is better than traditional box trainer in advanced laparoscopic suture ability training of catechumen.
目的
探讨腹腔镜虚拟现实模拟器在腹腔镜缝合能力培训中的应用价值。
方法
26名学员完成腹腔镜基本技能虚拟现实培训后，随机分为两组，一组采用腹腔镜虚拟现实模拟器进行高级腹腔镜技能（缝合技术）培训（虚拟组），另一组采用腹腔镜箱式训练器（箱式组）。使用自制模拟物，在分组前和训练后，每位学员在腹腔镜下进行肾盂输尿管吻合术，记录并评估手术时间、吻合质量和熟练程度。
结果
虚拟组分组前手术时间、吻合质量和熟练程度评分分别为（98±11）分钟、3.20±0.41、3.47±0.64，训练后分别为（53±8）分钟、6.87±0.74、6.33±0.82，差异均有统计学意义（均P<0.01）。箱式组分组前分别为（98±10）分钟、3.17±0.39、3.42±0.67，训练后分别为（52±9）分钟、6.08±0.90、6.33±0.78，差异也均有统计学意义（均P<0.01）。训练后，虚拟组的手术时间和熟练程度评分与箱式组相似（均P>0.05），但虚拟组的吻合质量评分高于箱式组（P=0.02）。
结论
在学员的高级腹腔镜缝合能力培训中，腹腔镜虚拟现实模拟器优于传统的箱式训练器。
