Objective

The objective was to compare results of two groups of population (novices and experts) on a virtual reality simulator of hysteroscopy resection for different metrics and for a multimetric score to assess its construct validity.

Material and Methods

Nineteen gynecologist who had at least 5 years of experience with hysteroscopy and self-evaluated their expertise at 4/5 or 5/5 were included as expert population. Twenty first-year gynecology residents in Paris were included as novice population. A standardized set of 4 hysteroscopy resection cases (polypectomy, myomectomy, roller ball endometrial ablation and septum resection) was performed on a virtual reality simulator (HystSim™) by the group of novices and experts. Results obtained on the simulator for overall score and for the parameters were compared by applying the Mann–Whitney test.

Results

Overall score of novices and experts were significantly different for three resection cases (polypectomy P < 0.001, myomectomy P < 0.001, roller ball endometrial ablation <0.001). The overall score was not different in the septum resection (P = 0.456). For the four cases, the economy score (included cumulative path length, procedure time and camera alignment) were statistically different between novices and experts (polypectomy P < 0.001, myomectomy P = 0.001, roller ball endometrial ablation P < 0.001, septum resection P < 0.001).

Conclusion(s)

The overall score on HystSim™ was able to discriminate novices between experts on polypectomy, myomectomy and roller ball endometrial ablation cases but not on septum resection. The economy score was the more reliable to reflect the surgeon experience. It could be used to evaluate and to train students on hysteroscopic resection on a virtual reality simulator.
