Objective assessment of psychomotor skills in surgery is now a priority; however, this assessment is difficult to achieve because of measurement difficulties associated with the reliability and validity of assessing surgical skills in vivo and in the laboratory. In this study virtual reality (VR) was used to overcome these problems in the objective psychomotor assessment of senior, junior, and novice laparoscopists. Twelve experienced laparoscopic surgeons (performed >50 Minimal Access Surgery (MAS) procedures), 12 inexperienced laparoscopic surgeons (<10 MAS procedures), and 12 laparoscopic novices (no MAS procedures) participated in the study. Each subject completed all six tasks of the Minimally Invasive Surgical Trainer; Virtual Reality (MIST VR). In comparison to the other groups, experienced laparoscopic surgeons performed the tasks significantly (p < 0.01) faster, had a lower error rate, were more economic in their movement of surgical instruments and in the use of diathermy. As a group they also showed greater consistency in their performance. MIST VR distinguished between the three groups of laparoscopists. VR provides a useful objective assessment tool for evaluating psychomotor skills for laparoscopic surgery.
目前，对外科手术中精神运动技能进行客观评估是当务之急；然而，由于在体内和实验室环境下评估手术技能的可靠性和有效性存在测量困难，这种评估难以实现。在本研究中，虚拟现实（VR）被用于克服这些问题，以对资深、初级和新手腹腔镜手术医生进行客观的精神运动评估。12名经验丰富的腹腔镜外科医生（完成了>50例微创手术（MAS））、12名经验不足的腹腔镜外科医生（<10例MAS）和12名腹腔镜手术新手（未进行过MAS）参与了该研究。每位受试者都完成了微创外科手术训练器；虚拟现实（MIST VR）的所有六项任务。与其他组相比，经验丰富的腹腔镜外科医生完成任务的速度明显更快（p<0.01），错误率更低，手术器械的移动和电刀的使用更经济。作为一个群体，他们在表现上也表现出更大的一致性。MIST VR区分了三组腹腔镜手术医生。VR为评估腹腔镜手术的精神运动技能提供了一种有用的客观评估工具。
