While older computer simulation models utilize mannequins, newer simulators are based on virtual reality (VR) [26]. Two major VR simulators available for training in upper endoscopy include GI Mentor™ (Figure 5.14) by 3D Systems (formerly Simbionix; 3D System Ltd., Airport City, Israel) and CAE EndoVR Simulator (CAE Healthcare, Montreal, Quebec, Canada). Both simulators provide a large library of simulated cases that train in basic endoscopic skills and escalate in procedural difficulty to more complicated scenarios such as emergent GI bleeding. These simulators also feature scope locators, pain indicators, and virtual patient feedback. The primary disadvantage for both systems is high cost.

In a randomized study, novice fellows were assigned to either 10 hours of preclinical training on the former Simbionix simulator or to no simulator training. Each trainee then performed EGDs in 20 subjects. The trainees who received simulator training demonstrated more complete procedure rates and required less instructor assistance [27]. Another study using the former Simbionix simulator randomized half of the medical residents to 5 hours of simulator‐based training in EGD and demonstrated that this group had higher skill level for performance parameters measured during subsequent live EGD cases [28]. A recent systematic review concluded that virtual endoscopy simulator training was more effective than bedside teaching or other interventions for novice endoscopists: the percentage of independently completed EGDs was 88% with simulator training compared to 70% in the non‐simulator training group [29].
