“…Some authors have demonstrated that box trainers are an effective alternative to virtual reality simulators, demonstrating that they have equal or better didactic effect when compared to virtual reality simulators [23][24][25][26]. Amongst other arguments, it has also been suggested that haptic feedback in VRS may not be as realistic as the one provided by box trainers [27].…”

Background: Practice on Virtual Reality simulators (VRS) have been shown to improve surgical performance. However, VRS are expensive and usually housed in surgical skills centres that may be inaccessible at times convenient for surgical trainees to practice. Conversely, box trainers are inexpensive and can be used anywhere at anytime. This study assesses "take-home" Box Trainers (BT) 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 randomised to two groups. Trainees were asked to practice 3 basic laparoscopic tasks for 6 weeks (BT group using a "take-home" box trainer; VR group using VRS in clinical skills centres). After the practice period all performed two LC, one on a VRS and one on a BT; (i.e. post-training assessment). VRS provided metrics (total time (TT), number of movements (NOM) instrument tip path length (PL)) and expert video assessment of cholecystectomy in a BT (GOALS score) were recorded. Performance during pre-and post-training 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.

“…In one such study by Mohammadi et al, 21 they found that training on the VRS improves performance on a box trainer enough to be considered a reasonable alternative training tool. Another study by Debes et al 11 demonstrated the opposite to be true, that is, the skills obtained on VRS are easily transferable to BT and not vice versa.…”

“…Naturally, a stimulator-designated target-based training strategy cannot be achieved with the box-trainer, which nevertheless gives comparable training effectiveness [23]. Similarly, while trying to reduce training cost, application of virtual trainers without a haptic option (sensation of touch) was found to be equally effective [21].…”

IntroductionIn the era of flowering minimally invasive surgical techniques there is a need for new methods of teaching surgery and supervision of progress in skills and expertise. Virtual and physical box-trainers seem especially fit for this purpose, and allow for improvement of proficiency required in laparoscopic surgery.Material and methodsThe study included 34 students who completed the authors‘ laparoscopic training on physical train-boxes. Progress was monitored by accomplishment of 3 exercises: moving pellets from one place to another, excising and clipping. Analysed parameters included time needed to complete the exercise and right and left hand movement tracks. Students were asked to do assigned tasks prior to, in the middle and after the training.ResultsThe duration of the course was 28 h in total. Significant shortening of the time to perform each exercise and reduction of the left hand track were achieved. The right hand track was shortened only in exercise number 1.ConclusionsExercises in the laboratory setting should be regarded as an important element of the process of skills acquisition by a young surgeon. Virtual reality laparoscopic training seems to be a new, interesting educational tool, and at the same time allows for reliable control and assessment of progress.
