Background:  Endoscopic submucosal dissection (ESD) is an innovative and promising procedure. However, ESD experience is mostly limited to Japan and a few countries in Asia. An appropriate training system should be proposed from Japan to promote a permeation of ESD technique. We conducted questionnaire survey to representative Japanese experts to reveal their training method of ESD for upper gastrointestinal neoplasm

Materials and Methods:  We sent the questionnaire on gastric and esophageal ESD to 9 Japanese experts in ESD. The questionnaire results were discussed in a session of Endoscopic Forum Japan 2011 held in Tokyo.

Results:  The inception criteria consisted of two main elements, diagnostic ability and primary endoscopy technique of preceptees. Preceptees should observe and attend as many ESD cases as possible. Most of the experts recommend training with isolated or live animal stomach or esophagus. Lesion in the distal stomach is the most suitable for the first real ESD by a preceptee. Being proficient in a gastric ESD is needed before starting esophageal ESD. Preceptor should have significantly high level of diagnostic ability and proficient ESD techniques in the colorectum as well as the stomach and esophagus.

Conclusion:  The present questionnaire survey seems to reveal basic elements required for ESD training program. We believe that this is also helpful in other countries where ESD would be initiated and penetrated safely and properly.
