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. Copyright © 2013 John Wiley & Sons, Ltd.
