Summary
A new 3D-printed simulator enhances training for colonic stent placement in malignant obstruction. This tool allows safe practice of self-expandable metal stent (SEMS) insertion at various locations, improving operator skills.
Area of Science:
- Medical Simulation
- Gastroenterology
- Interventional Endoscopy
Background:
- Colonic stenting is crucial for acute malignant colonic obstruction.
- Self-expandable metal stents (SEMS) are increasingly used.
- Training for SEMS placement is vital due to anatomical challenges.
Purpose of the Study:
- To develop and evaluate an innovative simulator for colonic stent placement training.
- To provide a realistic and safe environment for practicing SEMS insertion at diverse colonic locations.
Main Methods:
- Utilized 3D printing and silicone molding for simulator fabrication.
- Converted CT and colonoscopy images into 3D printable stereolithography files.
- Employed fused deposition modeling with acrylonitrile butadiene styrene copolymers.
Main Results:
- The simulator accurately replicates human colon anatomy and texture.
- It facilitates training in colonoscopy insertion, cecum intubation, and stenting in stenotic areas.
- Interchangeable modules for rectal, sigmoid, descending, and ascending colon stenting were incorporated.
- Modules feature integrated tumor contours and vasculature for enhanced visualization.
- Successful and repeatable SEMS insertion and expansion were demonstrated.
Conclusions:
- This novel simulator provides a safe platform for practicing colonic stenting.
- It aims to improve operator proficiency and potentially enhance clinical outcomes.
- The simulator addresses the need for effective training in managing colonic obstruction.
