[Endoscopic strategies in minimal invasive therapy].

Due to higher detection rates of early gastrointestinal neoplasia endoscopic resection of early GI cancers or precancerous lesions is increasing. Endoscopic piece-meal resection (EMR) remains the standard technique for the endoscopic resection of large sessile colorectal adenomas. Cap-assisted EMR techniques show excellent long-term results in the endoscopic therapy of neoplastic Barrett's esophagus. For the endoscopic resection of early gastrointestinal cancers of more than 2 cm endoscopic submucosal dissection (ESD) is the method of choice. The value of endoscopic full thickness resection in the therapy of GI tumors remains to be seen.
