| Riassunto: | The endoscopic treatment of cancerous and precancerous lesions in the gastrointestinal (GI) tract has experienced major breakthroughs in the past years. Endoscopic mucosal resection (EMR) is a simple and efficient method for the treatment of most benign lesions in the GI tract. However, with the introduction of endoscopic submucosal dissection (ESD) and endoscopic full-thickness resection (EFTR), the scope of lesions eligible for endoscopic treatment has been widened significantly even in the colon. These methods are now being used routinely not just for the treatment of benign lesions but also in the curative en bloc resection of early colorectal cancers. The quick, efficient, and noninvasive character of these endoscopic procedures make them not just an alternative to surgery but, in many cases, the methods of choice for the treatment of most early colon cancers and some rectal cancers.
