背景资料：方法：采用微创手术训练-虚拟现实（MIST-VR）训练仪，对27名高中生进行简单水平的测试，前瞻性地随机分为8个简单水平的训练课程结果：两组患者基线时均无统计学差异（P > 0. 05）。在训练期间，所有评分均显著提高（50.1%至81.3%）（p < 0.05）。虽然A组的成绩在整个训练过程中显著优于B组的成绩（p < 0.05），但在最后的测试中，B组在除TransferPlace（p = 0.054）外的所有任务上均优于A组。结论：虚拟模拟是一种有效的新手腹腔镜训练方法，在相对较短的时间内显著提高了技能水平。更具挑战性的训练似乎预示着随着时间的推移会有更大的进步，最终的技能水平也会更高。
Background: Virtual reality simulation is effective in training the novice to perform basic laparoscopic skills.Methods: Using the Minimally Invasive Surgery Training-Virtual Reality (MIST-VR) trainer, 27 honors high school students were tested at the easy level, prospectively randomized to eight training sessions at the easy (group A, n = 14) or medium (group B, n = 13) level, then retested at the easy level.Results: Both groups were statistically similar at baseline. All scores improved significantly (50.1% to 81.3%) over the period of training (p < 0.05). Although the group A scores were significantly better than the group B scores throughout training (p < 0.05), on final testing at the easy level, group B surpassed group A for all the tasks except TransferPlace (p = 0.054).Conclusions: Virtual simulation is an effective laparoscopic training method for the novice, providing significant improvement in skill levels over a relatively short period. More challenging training seems to predict greater improvement over time and better final skill levels.
