Development of a novel esophageal stricture simulation

Area of Science:

• Gastroenterology
• Medical Simulation
• Surgical Education

Background:

• Esophageal stricture dilatation is associated with significant risks.
• Acquiring adequate training for this procedure can be challenging.

Purpose of the Study:

• To assess the face validity of a novel esophageal stricture simulation.
• To evaluate its effectiveness in training balloon-dilatation techniques.

Main Methods:

• A mechanical model was adapted into single-use stricture simulations.
• Face validity was assessed via questionnaire after a 40-minute training session.
• Performance improvement was evaluated in a randomized controlled trial.

Main Results:

• The simulation was rated as good/excellent and realistic by trainees and instructors.
• 74% found the dilation realistic, and 91% found it useful for learning.
• Simulation use led to significant performance improvements compared to controls.

Conclusions:

• The novel simulation possesses good face validity and enhances performance in balloon-dilatation training.
• It offers a safe alternative for practice, eliminating patient risk and the need for animal models.
