Objective of the study: The study was carried out to validate the role of virtual reality computer simulation as a method for assessment of psychomotor skills in gastrointestinal endoscopy. We aimed to investigate whether the computer system was able to differentiate between subjects with different experience with GI endoscopy.
Methods and Procedures: Twenty-four surgeons and medical gastroenterologists were included in the study. They were divided into two groups according to their experience with GI endoscopy: experienced (performed> 200 endoscopic procedures) and unexperienced (performed <100 endoscopic procedures). All participants performed level 1 of the Cyberscopy task on an endoscopy simulator GI Mentor II). Assessment of endoscopic skills was based on three parameters - time, error score (sum of number of punctured objects and number of wall collisions), and economy score (sum of economy of movement- and confidence of manipulations scores). Time- and error scores were measured by the computer system, while economy score was assessed by a observer with big experience in GI endoscopy.
Results: Significant differences in performance existed between the 2 groups. Experienced endoscopists performed faster (Mann-Whitney’s test, p<0.001), made less errors (Mann-Whitney’s test, p=0.006) and demonstrated better economy score (Mann-Whitney’s test, p=0.005) than unexperienced.
Conclusion: The VR simulator was able to differentiate between subjects with different endoscopic experience. This indicates GI Mentor measures skills relevant for GI endoscopy and can be used in training programs as an assessment tool.
