Background and Objectives: To evaluate whether training on a virtual reality laparoscopic simulator improves the performance on a laparoscopic box trainer. Methods: Twenty-six subjects were trained using a box trainer, and 17 participants were trained using a virtual simulator. Participants in the experimental group completed 1 session of 5 exercises on the box trainer, 4 sessions on the virtual simulator, and a final session on the box trainer. Participants in the control group completed 6 sessions of 5 exercises on the box trainer alone. Exercises were monitored and scored for time and accuracy. Participants completed a self-evaluation survey after each session and a user satisfaction questionnaire at the end of the training. Results: No significant difference existed between the 2 groups in improvement of accuracy. Pegboard time (P 0.0110) and pattern cutting time (P 0.0229) were the only exercise parameters that improved significantly more in the control group compared with the experimental group. The experimental group developed more interest in a surgical field as a result of their experience than the control group did (70.6% vs 53.8%, respectively). Conclusion: The virtual simulator is a reasonable alternative to the box trainer for laparoscopic skills training.
