Interactive training with a novel simulation model for upper gastrointestinal endoscopic hemostasis improves trainee...

Area of Science:

• Medical Simulation
• Gastroenterology
• Surgical Education

Background:

• Endoscopic hemostasis training traditionally involves high-risk patient procedures.
• Simulation models for endoscopic hemostasis are not widely reported.
• A novel simulator, "Medical Rising STAR-Ulcer type," was developed for practicing hemoclip and coagulation grasper techniques.

Purpose of the Study:

• To evaluate the clinical difficulty reproducibility of the novel simulator.
• To assess the effectiveness of simulation-based training for clipping hemostasis.
• To measure improvements in trainee proficiency and confidence.

Main Methods:

• Prospective educational study involving 50 gastroenterology residents from Japan and Canada.
• Participants underwent simulation-based training using the "Medical Rising STAR-Ulcer type" simulator.
• Primary outcome: clipping hemostasis success rate; secondary outcomes: subjective assessment scores and co-occurrence network analysis of trainee comments.

Main Results:

• Hemostasis success rate increased significantly from 64% to 86% post-instruction (P < 0.05).
• Higher difficulty was observed for upper stomach ulcers compared to antrum ulcers, even after training.
• Trainee self-perceived proficiency and confidence significantly improved post-simulation (P < 0.05).

Conclusions:

• The developed simulation model is a valuable tool for enhancing technical skills in endoscopic hemostasis.
• Simulation-based training effectively improves trainee confidence and procedural success rates.
• The simulator demonstrates potential for safe and effective practice of gastrointestinal bleeding management.
