Summary
Cadaver surgical training (CST) using Thiel-embalmed cadavers is a feasible method for practicing duodenal endoscopic submucosal dissection (ESD). This innovative approach effectively replicates the procedure, aiding skill acquisition for endoscopists.
Area of Science:
- Gastroenterology
- Surgical Education
- Anatomical Preservation
Background:
- Duodenal endoscopic submucosal dissection (ESD) presents significant technical challenges and risks.
- Effective training models are crucial for improving duodenal ESD outcomes.
Purpose of the Study:
- To evaluate the feasibility and educational value of duodenal ESD training using Thiel-embalmed cadavers.
- To assess the realism and technical difficulty of simulated duodenal ESD in a cadaver model.
Main Methods:
- Four Thiel-embalmed cadavers underwent simulated upper gastrointestinal endoscopy and duodenal ESD on seven lesions.
- Seven endoscopists (three experts, four trainees) participated and provided feedback via questionnaires.
Main Results:
- Thiel-embalmed cadavers successfully simulated upper gastrointestinal endoscopy and duodenal ESD.
- High scores for procedural realism and educational value were reported by participants.
- Perforations occurred in two lesions, reflecting clinical challenges in thin duodenal submucosa.
Conclusions:
- Thiel-embalmed cadaver surgical training (CST) is a feasible and realistic model for duodenal ESD.
- CST demonstrates potential for acquiring duodenal ESD skills, despite psychological stress.
- Further validation with objective outcome measures is recommended for this training method.
