To evaluate whether training on a virtual reality laparoscopic simulator improves the performance on a laparoscopic box trainer.
Twenty-six subjects were trained using a box trainer, and 17 participants were trained using a virtual simulator. Participants in the experimental group completed 1 session of 5 exercises on the box trainer, 4 sessions on the virtual simulator, and a final session on the box trainer. Participants in the control group completed 6 sessions of 5 exercises on the box trainer alone. Exercises were monitored and scored for time and accuracy. Participants completed a self-evaluation survey after each session and a user satisfaction questionnaire at the end of the training.
No significant difference existed between the 2 groups in improvement of accuracy. Pegboard time (P=0.0110) and pattern cutting time (P=0.0229) were the only exercise parameters that improved significantly more in the control group compared with the experimental group. The experimental group developed more interest in a surgical field as a result of their experience than the control group did (70.6% vs 53.8%, respectively).
The virtual simulator is a reasonable alternative to the box trainer for laparoscopic skills training.
评估虚拟现实腹腔镜模拟器训练是否能提高在腹腔镜箱式训练器上的操作表现。
26名受试者使用箱式训练器进行训练，17名参与者使用虚拟模拟器进行训练。实验组参与者在箱式训练器上完成1节包含5项练习的课程，在虚拟模拟器上完成4节课程，最后在箱式训练器上再完成1节课程。对照组参与者仅在箱式训练器上完成6节包含5项练习的课程。对练习进行时间和准确性的监测与评分。参与者在每节课程后完成一份自我评估调查问卷，并在训练结束时完成一份用户满意度问卷。
两组在准确性提高方面无显著差异。与实验组相比，对照组中仅挂板时间（P = 0.0110）和图案切割时间（P = 0.0229）这两个练习参数有更显著的改善。由于训练经历，实验组对手术领域产生的兴趣比对照组更多（分别为70.6%和53.8%）。
对于腹腔镜技能训练，虚拟模拟器是箱式训练器的合理替代方案。
