To evaluate whether training on a virtual reality laparoscopic simulator improves the performance on a laparoscopic box trainer. 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. 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). The virtual simulator is a reasonable alternative to the box trainer for laparoscopic skills training.
