Abstract

Background

Before surgical simulators can be implemented for assessment of surgical training, their construct validity should be assessed.

Methods

Nine novices (NOV), nine medical students (MS), and nine residents (RES) underwent a laparoscopic skills training on the virtual reality (VR) simulator Lap Mentor®. Assessment of laparoscopic skill was based on parameters measured by the computer system before and after training.

Results

Significant difference existed between RES and NOV at seven of nine tasks before training on the VR simulator. After the training in some tasks significant differences were observed between the experienced group (RES) and the nonexperienced groups (MS and NOV) or between medical groups (RES and MS) and nonmedical group (NOV).

Conclusions

Performance parameters of the Lap-Mentor® can be used to distinguish between subjects with varying laparoscopic experience.
