“…In a recent study, Perretta et al showed the feasibility of modifying a laparoscopy trainer to allow flexible endoscopy training on this model. Their model adopted some basic tasks derived from laparoscopy training to simulate endoscopic procedures such as snaring, injection, clipping and even selective cannulation [19].…”

Background and study aims Current data show that traditional training methods in endoscopic retrograde cholangiopancreatography (ERCP) fall short of producing competent trainees. We aimed to evaluate whether a novel approach to simulator-based training might improve the learning curve for novice endoscopists training in ERCP. Methods We conducted a multicenter, randomized controlled trial using a validated mechanical simulator (the Boškoski-Costamagna trainer). Trainees with no experience in ERCP received either standard cannulation training or motion training before undergoing standard cannulation training on the mechanical simulator. Trainees were timed and graded on their performance in selective cannulation of four different papilla configurations. Results Thirty-six trainees (16 in the motion training group, 20 in the standard group) performed 720 timed attempts at cannulating the bile duct on the simulator. Successful cannulation was achieved in 698 of 720 attempts (96.9 %), with no significant difference between the two study groups (P = 0.37). Trainees in the motion training group had significantly lower median cannulation times compared to the standard group (36 vs. 48 seconds, P = 0.001) and better technical performance on the first papilla type (P = 0.013). Conclusions Our findings suggest that motion training could be an innovative method aimed at accelerating the learning curve of novice trainees in the early phase of their training. Future studies are needed to establish its role in ERCP training programs.

Regaining orientation during an endoscopic procedure is critical. We investigated how endoscopists maintain orientation based on video and eye gaze analysis. Novices and experts performed a simulated colonoscopy procedure. Task performance was assessed by completion time, total distance traveled, maximum depth of insertion, percentage of mucosa viewed, and air insufflation volume. Procedure videos were analyzed by transfers among three viewing areas: center of bowel lumen, edge of bowel lumen, and other structure without bowel lumen in sight. Performers' gaze features were also examined over these viewing areas. Experts required less time to complete the procedure (P < 0.001). Novices' scope traveled a greater distance (P < 0.001) and more scope was inserted compared to an expert (P < 0.001). Novices also insufflated more air than experts (P < 0.001). Experts maintained the view of bowel lumen in the middle of the screen, while novices often left it on the edge (P = 0.032). When disorientation happened, novices brought the view to the edge more frequently than the center. However, experts were able to bring it back to the center directly. Eye tracking showed that the rate of saccades in experts increased when the bowel lumen moved away from the central view, such a behavior was not observed in novices. Maintaining a centered view of the bowel lumen is a strategy used by expert endoscopists. Video and eye tracking analysis revealed a key difference in eye gaze behavior when regaining orientation between novice and experienced endoscopists.
