“…Two of the possible reasons proposed by the authors were small sample size and introduction of the didactic intervention too late in the learning curve [35]. These are applicable in our study as the number of participants who completed the study is limited and participants were not complete novices.…”

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.

“…Unfortunately, this is a rather frequent occurrence in educational studies [20,3,19,35,2]. Assessing the clinical impact of the study is methodologically challenging, as a number of participants did not have the opportunity to perform real laparoscopic cholecystectomies immediately after the completion of the study.…”

“…Trained groups generally made fewer errors, and had less instances of supervising surgeon takeover than participants who did not have the training (17). Nine randomised trials of VR simulators and one of a video assisted simulator were identified to fill the inclusion criteria (Table 1) (18)(19)(20)(21)(22)(23)(24)(25)(26)(27). In addition, two earlier studies from the ASERNIP-S review were included to the analysis (28,29).…”

Virtual Reality Simulator Training of Laparoscopic Cholecystectomies — A Systematic Review

et al. 2012

Background and Aims: simulators are widely used in occupations where practice in authentic environments would involve high human or economic risks. surgical procedures can be simulated by increasingly complex and expensive techniques. this review gives an update on computer-based virtual reality (vr) simulators in training for laparoscopic cholecystectomies.Materials and Methods: from leading databases (medline, cochrane, embase), randomised or controlled trials and the latest systematic reviews were systematically searched and reviewed. twelve randomised trials involving simulators were identified and analysed, as well as four controlled studies. furthermore, seven studies comparing black boxes and simulators were included.Results: the results indicated any kind of simulator training (black box, vr) to be beneficial at novice level. after vr training, novice surgeons seemed to be able to perform their first live cholecystectomies with fewer errors, and in one trial the positive effect remained during the first ten cholecystectomies. no clinical follow-up data were found. optimal learning requires skills training to be conducted as part of a systematic training program. no data on the cost-benefit of simulators were found, the price of a vr simulator begins at eur 60 000.Conclusions: theoretical background to learning and limited research data support the use of simulators in the early phases of surgical training. the cost of buying and using simulators is justified if the risk of injuries and complications to patients can be reduced. Developing surgical skills requires repeated training. in order to achieve optimal learning a validated training program is needed.

GOALS rating scale 30 25 Also, in the same article, 100% of intervention members achieved the passing score level whereas it was just 37.5% of the control group. Researchers did not locate any statistical significance between the two groups; nonetheless, the members with low benchmark execution expanded their scores altogether after simulation training.…”
