Summary
This study found that the WIMAT colonoscopy suitcase simulator demonstrates excellent content validity for training endoscopic polypectomy skills. The simulator accurately replicates key aspects of the procedure, offering a valuable tool for medical education.
Area of Science:
- Medical Simulation
- Gastroenterology
- Surgical Training
Background:
- Endoscopic polypectomy requires extensive training due to its complexity.
- Simulation offers a safe environment for skill acquisition.
- A novel simulator was developed to aid in colonic polypectomy training.
Purpose of the Study:
- To assess the content validity of a new colonic polypectomy simulator.
- To evaluate the simulator's realism and effectiveness for training.
Main Methods:
- The Welsh Institute for Minimal Access Therapy (WIMAT) endoscopy suitcase was used.
- Participants (gastroenterologists, surgeon, nurse) performed a simulated polypectomy.
- A Likert scale questionnaire assessed the simulator's realism across 15 parameters.
Main Results:
- The simulator achieved high scores for mucosal realism, snare control, polyp handling, and mucosa raising.
- Overall simulation score was high (6.0), indicating excellent content validity.
- The simulator's difficulty level was comparable to real-life procedures.
Conclusions:
- The WIMAT colonoscopy suitcase exhibits excellent content validity for key polypectomy parameters.
- This simulator shows significant potential as an adjunct for medical training and assessment in endoscopy.
