Endoscopic Submucosal Dissection of Early Cancers, Flat Adenomas, and Submucosal Tumors in the Gastrointestinal Tract

ESD is technically feasible and shows promising results in this German single-center-study. ESD is time consuming and difficult but shows a learning curve resulting in a decrease of the procedural duration over time. R0 en bloc resection is mostly possible and can avoid the risk of local recurrence.
