Summary
A live pig model significantly improved endoscopic ultrasonography (EUS) skills for trainees, enhancing anatomical visualization and fine-needle aspiration (FNA) performance. This training model proved effective for EUS credentialing in pancreatic and biliary procedures.
Area of Science:
- Medical training and simulation
- Gastroenterology
- Surgical education
Background:
- Endoscopic ultrasonography (EUS) learning curve is steep, particularly for pancreatic and biliary interventions.
- A novel live pig model was developed in France for EUS credentialing.
Purpose of the Study:
- To evaluate the effectiveness of a live pig model in EUS training.
- To assess the impact on trainees' competence in diagnostic and interventional EUS procedures.
Main Methods:
- 17 trainees underwent hands-on EUS training using the live pig model.
- Procedures included anatomical visualization, fine-needle aspiration (FNA) of lymph nodes, and celiac neurolysis.
- Performance was assessed by time, precision, and technical errors.
Main Results:
- Significant improvements were noted in visualizing key anatomical structures (splenic vein/artery, vena cava, celiac tree, pancreas, bile duct).
- Fine-needle aspiration (FNA) showed improved duration and precision, though technical error rates did not significantly decrease.
- Celiac neurolysis improved in procedure time, but precision and technical error rates remained unchanged.
Conclusions:
- EUS training with a live pig model enhances competence in anatomical visualization and FNA.
- The model offers a valuable tool for EUS credentialing, improving diagnostic and some interventional skills.
