Endoscopic mucosal resection (EMR) and Endoscopic Submucosal Dissection (ESD) are advanced endoscopic techniques for the treatment of flat superficial tumors of the gastrointestinal tract. In this lecture, Prof. G. Kaehler presents the technique of selective fluid accumulation in the submucosa by pressure injection, the selective tissue elevation by pressure injection (STEP). All technical details are carefully described.
