Background: Endoscopic submucosal dissection (ESD) and peroral endoscopic myotomy (POEM) are recently developed techniques that have the potential to significantly improve clinical outcomes. However, training opportunities on these techniques remain limited. To address this issue, we developed a novel ex-vivo ESD/POEM training model. Our aim in this paper is to describe the model and provide preliminary evidence of promising feasibility to improve access to ESD/POEM training.
Methods: The model was developed using polyvinyl alcohol hydrogel, which can easily be modified to reproduce the stiffness of the different intestinal layers, namely the mucosa, submucosa, and muscle layer.
Results: A training workshop, using our ex-vivo model, was held for 28 residents. Satisfaction and feasibility in using the ex-vivo model for endoscopic training were evaluated by using a self-report questionnaire. All participants were satisfied with their training experience (100% satisfaction rate), with 27 of the 28 participants reporting that the model was feasible in replicating all components of the ESD/POEM technique (96.4% feasibility rate).
Conclusions: Based on this feedback, we propose that our non-biomaterial model has the feasibility to provide an effective endoscopy education tool and a satisfactory training experience.
