Abstract
BackgroundHysterectomy rates are decreasing in many countries, and virtual reality simulators bring new opportunities into residents’ surgical education. The objective of this study was to evaluate the effect of training in laparoscopic hysterectomy module with virtual reality simulator on surgical outcomes among residents performing their first laparoscopic hysterectomy.MethodsThis randomized study was carried out at the Department of Obstetrics and Gynecology in Helsinki University Hospital and Hyvinkää Hospital. We recruited twenty residents and randomly signed half of them to train ten times with the laparoscopic hysterectomy module on a virtual reality simulator, while the rest represented the control group. Their first laparoscopic hysterectomy was video recorded and assessed later by using the Objective Structured Assessment of Technical Skills (OSATS) forms and Visual Analog Scale (VAS). The scores and surgical outcomes were compared between the groups.ResultsThe mean OSATS score for the Global Rating Scale (GRS) was 17.0 (SD 3.1) in the intervention group and 11.2 (SD 2.4) in the control group (p = 0.002). The mean procedure-specific OSATS score was 20.0 (SD 3.3) and 16.0 (SD 2.8) (p = 0.012), and the mean VAS score was 55.0 (SD 14.8) and 29.9 (SD 14.9) (p = 0.001). Operative time was 144 min in the intervention group and 165 min in the control group, but the difference did not reach statistical significance (p = 0.205). There were no differences between the groups in blood loss or direct complications.ConclusionResidents training with a virtual reality simulator prior to the first laparoscopic hysterectomy seem to perform better in the actual live operation. Thus, a virtual reality simulator hysterectomy module could be considered as a part of laparoscopic training curriculum.
Highlights
Hysterectomy rates are decreasing in many countries, and virtual reality simulators bring new opportunities into residents’ surgical education
One participant trained with the hysterectomy module only four times, but her operation was included in the analysis
The residents in the intervention group were more experienced in training at obstetrics and gynecology and had done more laparoscopic procedures
