Virtual reality (VR) simulators now have the potential to replace traditional methods of laparoscopic training. The aim of this study was to compare the VR simulator with the classical box trainer and determine whether one has advantages over the other.
Twenty four novices were tested to determine their baseline laparoscopic skills and then randomized into the following three group: LapSim, box trainer, and no training (control). After 3 weekly training sessions lasting 30-min each, all subjects were reassessed. Assessment included motion analysis and error scores. Nonparametric tests were applied, and p < 0.05 was deemed significant.
Both trained groups made significant improvements in all parameters measured ( p < 0.05). Compared to the controls, the box trainer group performed significantly better on most of the parameters, whereas the LapSim group performed significantly better on some parameters. There were no significant differences between the LapSim and box trainer groups.
LapSim is effective in teaching skills that are transferable to a real laparoscopic task. However, there appear to be no substantial advantages of one system over the other.
虚拟现实（VR）模拟器目前有潜力取代传统的腹腔镜训练方法。本研究的目的是将VR模拟器与传统箱式训练器进行比较，并确定二者中是否一方比另一方具有优势。
对24名新手进行测试以确定其腹腔镜技能基线，然后随机分为以下三组：LapSim组、箱式训练器组和无训练组（对照组）。在进行了为期3周、每周3次、每次30分钟的训练后，对所有受试者进行重新评估。评估包括动作分析和错误评分。采用非参数检验，p < 0.05被认为具有统计学意义。
两个训练组在所有测量参数上均有显著改善（p < 0.05）。与对照组相比，箱式训练器组在大多数参数上表现明显更好，而LapSim组在一些参数上表现明显更好。LapSim组和箱式训练器组之间没有显著差异。
LapSim在教授可转化为实际腹腔镜任务的技能方面是有效的。然而，一个系统相对于另一个系统似乎没有实质性优势。
