Endoscopic Submucosal Dissection (ESD): How do Western Endoscopists Value Animal Models?

Aims Endoscopic Submucosal Dissection (ESD) was introduced in the West later than in East, which might have influenced the type of training on this technique. Only recently, suggestions for standardized training were described. Our aim was to assess how Western endoscopists performing ESD have been trained and how they value animal models for training.

Methods An online survey regarding training in ESD was sent to western endoscopists who published articles on advanced resection techniques.

Results From 279 endoscopists, 58 (21 %) completed the questionnaire, of which 50 confirmed performance of ESD in clinical practice. Endoscopists had a median of 15 years of endoscopic experience (IQR 9,75-20,25). All of them were performing conventional EMR, before starting ESD. Prior to clinical ESD practice, 74 % (n = 37) underwent training with ex vivo models (median of 2 courses (IQR 1-5)) and 84 % (n = 42) with live animal models (median of 2 courses (IQR 1-4)). After starting clinical ESD, as trainers, 52 % (n = 26) were involved with ex vivo models (median of 5 courses (IQR 2,75-10)) and 60 % (n = 30) with live animal models (median of 3 courses (IQR 2-10)). Personal usefulness of ex vivo and live animal models was rated with a median of 9 (IQR 8-10) and 10 (IQR 8-10), out of 10, respectively. Courses with ex vivo and live animal models were considered a prerequisite before clinical practice by 84 % (n = 42) and 78 % (n = 39), respectively.

Conclusions Western endoscopists have extensive endoscopic experience before starting ESD. The majority had pre-clinical training with ex vivo and live animal models and more than half of the respondents are acting as trainers of other endoscopists with these models. Animal models are considered very useful and deemed a prerequisite before clinical practice by the majority of the endoscopists.
