This study addresses target group reliability and task validity for training on a laparoscopic simulator.
Data were collected on 64 participants prospectively at the Department of OB/GYN, University Hospitals Schleswig-Holstein, Campus Kiel. The Simbionix LAP Mentor for laparoscopic simulation was used to test trainees. Each participant received a questionnaire to clarify his/her medical position, surgical experience, and previous virtual reality (VR) experience, including video gaming experience. Pre- and post-tests were performed. Performances were analyzed for task completion and total time.
All participants revealed a significant improvement in the post-test compared with the pre-test (p < .005), independent of their previous level of experience. Regarding accomplishment of the assigned task, the experts revealed in the pre-test an advantage in tasks 1-4 and 6-8. The beginners revealed wide-ranging improvements in tasks 3, 5, 8, and 9 between the pre-test and the post-test compared with novices in laparoscopic surgery (residents), and a wide range of improvements relative to experts. VR experience and video gaming exposure revealed an advantage in the pre-test; however, participants without previous exposure were able to narrow the gap, revealing extensive improvements in the post-test.
The trainer could be beneficial for medical students and surgical novices.
本研究探讨了腹腔镜模拟器训练的目标群体可靠性和任务有效性。
前瞻性收集了石勒苏益格-荷尔斯泰因大学医院基尔校区妇产科64名参与者的数据。使用Simbionix LAP Mentor腹腔镜模拟器对学员进行测试。每位参与者都收到一份问卷，以明确其医学职位、手术经验和以前的虚拟现实（VR）经验，包括视频游戏经验。进行了前测和后测。分析了任务完成情况和总时间的表现。
与前测相比，所有参与者在后测中均有显著改善（p < 0.005），与他们之前的经验水平无关。关于分配任务的完成情况，专家们在前测中在任务1-4和6-8中显示出优势。初学者与腹腔镜手术新手（住院医师）相比，在前测和后测之间在任务3、5、8和9中有广泛的改善，并且相对于专家有广泛的改善。VR经验和视频游戏接触在前测中显示出优势；然而，没有先前接触的参与者能够缩小差距，在后测中显示出广泛的改善。
该培训器对医学生和外科新手可能有益。
