Novel Simulator for Endoscopic Hemostasis Provides Opportunity to Foster Confidence and Interest in Endoscopic Therapy for Diverse Learners

Background
Many of the training for endoscopic treatment are currently done on real patients. These high-risk situations are not preferable for trainees to get skills. Therefore, we developed a novel GI bleeding simulator to practice endoscopic hemostasis with clips.
Method
The GI bleeding model consisted of disposable ulcer and reusable gastric lumen. The ulcer was made using an elastic resin, having several vessels on the surface can reproduce spurting bleeding. A trainer can control the difficulty by switching the ulcer location. For example, when it is placed on the greater curvature of the antral area, the endoscope is easy to stabilize and suitable for beginner trainees.
Result
As an international multicenter study in Japan and Canada, we have reported that the educational program with the GI bleeding model contributes to improving the confidence of hemostatic procedure and objective success rate in gastrointestinal residents (DDW2021). Furthermore, we are confirming the evidence that the simulator learning which was modified for beginner trainees improved the confidence of hemostatic procedure and willingness to repeat training among pediatric endoscopists and junior residents, too.
Conclusion
The novel endoscopic hemostasis simulator possibly improves skills and confidence at each trainee's level under a calm learning environment without putting patients at risk.
