Endoscopic Submucosal Dissection (ESD) Training and Performing ESD with Accurate and Safe Techniques

Introduction of endoscopic submucosal dissection (ESD) has brought about a renaissance in therapeutic endoscopy. For the globalization and universalization of ESD, the number of physicians who can perform ESD has rapidly increased with general ex vivo and in vivo training using animal models and hand-on courses. In this focused review series, world-renowned ESD experts described the published studies or their own precious experiences about ESD training and performing ESD with accurate and safe techniques. First, Dr. Adolfo Parra-Blanco reviewed on ex vivo and in vivo models for ESD training. Next, Dr. Joo Young Cho described detailed practical settings and current status of hands-on courses using ex vivo and in vivo models in Korea. Dr. Takashi Toyonaga described quality controlled ESD and basic techniques to prevent complications. Dr. Tsuneo Oyama reviewed recently published methods to facilitate ESD. Dr. Jae-Young Jang reviewed the usefulness of magnifying and narrow band imaging to measure the depth of invasion before ESD.
