Abstract
INTRODUCTION: Even though literature provides compelling evidence of the value of simulators for training of basic laparoscopic skills, the best way to incorporate them into a surgical curriculum is unclear. This study compares the training outcome of single modality training with multimodality training of basic laparoscopic skills. METHODS: Thirty-six medical students without laparoscopic experience performed six training sessions of 45 min each, one per day, in which four different basic tasks were trained. Participants in the single-modality group (S) (n = 18) practiced solely on a virtual reality (VR) simulator. Participants in the multimodality group (M) (n = 18) practiced on the same VR simulator (2x), a box trainer (2x), and an augmented reality simulator (2x). All participants performed a pre-test and post-test on the VR simulator (the four basic tasks + one additional basic task). Halfway through the training protocol, both groups performed a salpingectomy on the VR simulator as interim test. RESULTS: Both groups improved their performance significantly (Wilcoxon signed-rank, P < 0.05). The performances of group S and group M in the additional basic task and the salpingectomy did not differ significantly (Mann-Whitney U test, P > 0.05). Group S performed the four basic tasks in the post-test on the VR faster than group M (P ≤ 0.05), which can be explained by the fact that they were much more familiar with these tasks. CONCLUSIONS: Training of basic laparoscopic tasks on single or multiple modalities does not result in different training outcome. Both training methods seem appropriate for the attainment of basic laparoscopic skills in future curricula.
