This study assesses the transfer of laparoscopic skills to a group of Basic Surgical Trainees (BST) attending the Basic Surgical Skills (BSS) course.
The virtual reality simulator MIST-VR was used to assess 13 trainees before and after the course and again 3 weeks and 3 months later. Analysis of kinematic data using the Imperial College Surgical Assessment Device gave measures of distance traveled, distance efficiency ratio, time taken, number of errors made, and number of movements made in completing a virtual laparoscopic task. The performance of the group was compared to a control group who underwent no training.
All parameters improved significantly after the course, with the exception of distance traveled by the instruments. All outcome measures were significantly improved at 3 weeks. The control group showed a nonsignificant trend toward improvement in all parameters.
The Basic Surgical Skills course produces quantifiable improvements in laparoscopic skill that are measurable by MIST-VR. There is a learning effect associated with using MIST-VR alone.
本研究评估了腹腔镜技能向参加基础外科技能（BSS）课程的一组基础外科住院医师（BST）的传授情况。
使用虚拟现实模拟器MIST-VR在课程前后对13名学员进行评估，并在3周和3个月后再次评估。使用帝国理工学院外科评估设备对运动学数据进行分析，得出完成虚拟腹腔镜任务时的移动距离、距离效率比、用时、错误数量和动作数量。将该组学员的表现与未接受培训的对照组进行比较。
除器械移动距离外，课程结束后所有参数均有显著改善。所有结果指标在3周时均有显著改善。对照组在所有参数上均呈现出不显著的改善趋势。
基础外科技能课程在腹腔镜技能方面产生了可量化的改善，可通过MIST-VR进行测量。单独使用MIST-VR存在学习效应。
