背景
体壁对手术器械操作的“支点效应”是内窥镜外科新手的主要障碍。虚拟现实培训以前没有被评估为克服这一问题的手段。
材料和方法
要求16名没有内窥镜检查经验的参与者在腹腔镜实验室条件下在2分钟内制作多个定义的切口。一半的受试者被随机分配接受微创手术培训师虚拟现实（MIST VR）计算机程序的初始培训。
结果
在测试试验1中，接受MIST VR培训的参与者比对照组做出了更正确的切口（P = 0.0001），甚至在两组（P = 0.0001）进行了扩展练习之后。他们也更有可能主动使用双手执行内窥镜评价任务（P = 0.01）。
结论
虚拟现实培训是一种潜在的，可行的解决方案，为初级内窥镜，克服“支点效应”，在一个可复制的，安全的学习环境，允许客观和可靠的量化的技能水平的培训师。
BACKGROUND
The "fulcrum effect" of the body wall on surgical instrument manipulation is a major hurdle for novice endoscopic surgeons. Virtual reality training has not previously been evaluated as a means to overcome this problem.
MATERIALS AND METHODS
16 participants with no experience of endoscopy were required to make multiple defined incisions under laparoscopic laboratory conditions within 2-minute periods. Half of the subjects were randomized to receive initial training on the Minimally Invasive Surgical Trainer, Virtual Reality (MIST VR) computer programme.
RESULTS
Participants with MIST VR training made significantly more correct incisions (P = 0.0001) than the control group on test trial 1, and even after extended practice by both groups (P = 0.0001). They were also significantly more likely to actively use both hands to perform the endoscopic evaluation task (P = 0.01).
CONCLUSIONS
Virtual reality training represents a potential, viable solution for junior endoscopists, for overcoming the "fulcrum effect", in a replicable, safe learning environment which allows objective and reliable quantification of skill levels by trainers.
