Endoscopic submucosal dissection for early gastric cancer performed by supervised residents: assessment of feasibility and learning curve

Abstract

With appropriate supervision, gastric ESD by residents is feasible, with equivalent complete resection rates and acceptable complication rates compared with those of experienced endoscopists, although there was difficulty in achieving sufficient self-completion rates in submucosal dissection. Better control of bleeding during submucosal dissection may be a key to improving the procedure.
