BACKGROUND
Peg transfer is one of five tasks in the Fundamentals of Laparoscopic Surgery (FLS), program. This paper reports the development and validation of a Virtual Basic Laparoscopic Skill Trainer-Peg Transfer (VBLaST-PT(©) ) simulator for automatic real-time scoring and objective quantification of performance.
METHODS
New techniques have been introduced in order to allow bi-manual manipulation of pegs and automatic scoring/evaluation while maintaining high quality of simulation. A preliminary face and construct validation study was performed with 22 subjects divided into two groups: experts (PGY 4-5, fellow and practicing surgeons) and novice (PGY 1-3).
RESULTS
Face validation shows high scores for all aspects of the simulation. Two-tailed Mann-Whitney U-test scores showed significant differences between the two groups on completion time (P = 0.003), FLS score (P =0.002) and the VBLaST-PT© score (P = 0.006).
CONCLUSIONS
VBLaST-PT(©) is a high quality virtual simulator that showed both face and construct validity.
背景
钉棒转移是腹腔镜手术基础（FLS）课程中的五项任务之一。本文报告了一种用于钉棒转移的虚拟基础腹腔镜技能训练器（VBLaST-PT(©)）模拟器的开发与验证，该模拟器可对操作进行自动实时评分和客观量化。
方法
引入了新技术，以便在保持高质量模拟的同时实现钉棒的双手操作以及自动评分/评估。对22名受试者进行了初步的表面效度和结构效度研究，这些受试者分为两组：专家（四年级至五年级住院医师、研究员和执业外科医生）和新手（一年级至三年级住院医师）。
结果
表面效度显示模拟的各个方面得分都很高。两尾曼-惠特尼U检验分数显示，两组在完成时间（P = 0.003）、FLS分数（P = 0.002）和VBLaST-PT©分数（P = 0.006）方面存在显著差异。
结论
VBLaST-PT(©)是一种高质量的虚拟模拟器，具有表面效度和结构效度。
