An approach to endoscopic submucosal dissection (ESD) and advanced colonoscopic skills training based on inanimate and ex vivo animal large bowel models

Endoscopic submucosal dissection is a challenging technique that allows en bloc removal of sessile colorectal polyps and constitutes definitive treatment for superficial T-1 cancers. To successfully complete ESD cases, the great majority of endoscopists need to acquire several new skill sets. Learning about, practicing, and becoming proficient with the advanced skills in the clinical setting is a huge challenge because of the fact that these are usually low volume cases and there may be weeks or months between cases.
