Evaluating hysteroscopy virtual-reality training simulators

VirtaMed GynoS™ Hysteroscopy

Background

The aim of this study was to establish the training capacity and realism of a new virtual-reality simulator for the training of hysteroscopic interventions, GynoS™ Hysteroscopy.

Methods

At the 13th Practical Course in Gynaecologic Endoscopy in Davos, Switzerland, sixty-two gynecological surgeons with different levels of expertise were interviewed. All participants filled out a four-page questionnaire and received a 20-min hands-on training on the simulator.

With respect to the realism of the simulation and the training capacity, 23 questions were answered on a seven-point Likert scale together with 11 agree/disagree statements concerning the general GynoS™ training.

Results

Twenty-six participants had carried out over 50 hysteroscopies (‘experts’) and 36 equal to or fewer than 50 (‘novices’). Of the responding participants, 4 of 60 (6.6%) judged the overall impression as ‘7 – absolutely realistic,’ 40 (66.6%) as ‘6 – realistic,’ and 16 (26.6 %) as ‘5 – somewhat realistic.’

High-grade acceptance was found in both groups, but novices (6.48; 95% confidence interval [CI] 6.28–6.7) rated the overall training capacity much higher than experts (6.08; 95% CI 5.85–6.3).

In response to the statements, 95.2% believe that GynoS™ enables procedural training of diagnostic and therapeutic hysteroscopy, and 85.5% suggest that before performing surgery on real patients, GynoS™ Hysteroscopy training should be offered to all novices.

Conclusion

Face validity has been established for a new hysteroscopic surgery simulator. Potential trainers and trainees assess it to be a useful and realistic tool for the training of hysteroscopy. In order to clarify how this system can be optimally integrated into the gynecological curriculum, further systematic validation studies are required.

Background

Minimally invasive surgery is a major pillar of gynecological surgery. Yet, due to the cost and equipment requirements of organ simulators, there are very few training opportunities outside the operation theater (OR), so virtual reality trainers (VRT) are the ideal tools to fill this gap.

Methods

The standardized GynoS™-VRT training program was followed by experienced and inexperienced participants of a minimally invasive surgery course.

Results

The performance of 39 Participants (15 inexperienced and 24 experienced) was assessed in the standardized hysteroscopic program GynoS™. Tasks included three rounds of both a polyp and a myoma resection. Primary measurements were cumulative resection path length, improvement in resection time and distention media use.

Conclusion

The GynoS™-VRT is an effective tool to enhance the psychomotor skills required in hysteroscopic surgery for experienced and inexperienced surgeons before OR exposure. For hysteroscopic haptic skills, further organ models training is advisable.
