Background Practice on virtual reality simulators (VRSs) has been shown to improve surgical performance. However, VRSs are expensive and usually housed in surgical skills centers that may be inaccessible at times convenient for surgical trainees to practice. Conversely, box trainers (BT) are inexpensive and can be used anywhere at anytime. This study assesses “take-home” BTs as an alternative to VRS. Methods After baseline assessments (two simulated laparoscopic cholecystectomies, one on a VRS and one on a BT), 25 surgical trainees were randomized to two groups. Trainees were asked to practice three basic laparoscopic tasks for 6 wk (BT group using a “take-home” box trainer; VR group using VRS in clinical skills centers). After the practice period, all performed two laparoscopic cholecystectomy, one on a VRS and one on a BT; (i.e., posttraining assessment). VRS provided metrics (total time [TT], number of movements instrument tip path length), and expert video assessment of cholecystectomy in a BT (Global Operative Assessment of Laparoscopic Skills [GOALS] score) were recorded. Performance during pretraining and posttraining assessment was compared. Results The BT group showed a significant improvement for all VRS metrics ( P = 0.008) and the efficiency category of GOALS score ( P = 0.03). Only TT improved in the VRS group, and none of the GOALS categories demonstrated a statistically significant improvement after training. Finally, the improvement in VRS metrics in the BT group was significantly greater than in the VR group (TT P = 0.005, number of movements P = 0.042, path length P = 0.031), although there were no differences in the GOALS scores between the groups. Conclusions This study suggests that a basic “take-home” BT is a suitable alternative to VRS. [ABSTRACT FROM AUTHOR] |
