Kurzfassung

BACKGROUND AND STUDY AIMS Skills in gastrointestinal endoscopy mainly depend on experience and practice. Training on endoscopy simulators may decrease the time needed to reach competency in endoscopy. The purpose of the study was to determine whether the GI-Mentor, a virtual reality endoscopy simulator, can distinguish between beginners and experts in endoscopy and to assess whether training improves the performance of beginners. METHODS A total of 13 beginners and 11 experts (more than 1,000 procedures) in gastrointestinal endoscopy were included. The baseline assessment consisted of virtual endoscopies and skill tests. The beginners were randomly allocated to receive training (n = 7) or no training (n = 6). The training group was allowed to practice using the simulator for 2 hours per day. After 3 weeks participants were re-evaluated with two new virtual endoscopy cases and one virtual skill test. Insertion time, correctly identified pathologies, adverse events and skill test performance were recorded. RESULTS The baseline assessment revealed significant differences favoring the experts for virtual endoscopies and skill tests. Significant differences in favor of experts were found for successful retroflection during esophagogastroduodenoscopy (EGD) (P < 0.005); adverse events during colonoscopy (P < 0.02); insertion time (P < 0.001); correctly identified pathologies in gastroscopy and colonoscopy (P < 0.02); and skill test performance (P < 0.01). The final evaluation showed significant differences between training and no-training groups, in favor of the training group, for the number of adverse events during virtual endoscopy (P < 0.04), for the insertion time during colonoscopy (P < 0.03); and for skill test performance (P < 0.01). The training group improved its abilities on the simulator significantly. Differences between experts and the training group were no longer seen. CONCLUSION This virtual endoscopy simulator is capable of identifying differences between beginners and experts in gastrointestinal endoscopy. A 3-week training improves the performance of beginners significantly. This quite fast improvement in endoscopic skills certainly cannot be seen in clinical practice; no conclusions can be made about the impact of virtual simulator training on real-life endoscopy, and this must be evaluated.
