Core tip: This mini review focuses on endoscopic submucosal dissection (ESD) training. ESD is a relatively novel advanced technique used for en bloc resection of gastrointestinal early neoplasia. ESD training has become a challenge for Western endoscopists due to several factors: low detection rate of early gastric cancer, the perfect scenario for starters; lack of experts in the technique for adequate tutoring; and finally, most of the target lesions in Western countries are colorectal neoplasias, representing the highest peak of difficulty in ESD. We will review some of the most important steps that could shape a training program in ESD, including animal training. Particular attention is focused on colorectal ESD.
