Endoscopic Mucosal Resection Versus Endoscopic Submucosal Dissection for Colorectal Laterally Spreading Lesions.

"Endoscopic mucosal resection (EMR) is an endoscopic resection technique that allows the removal of large colorectal lesions using a conventional lift-and-cut procedure or an underwater technique"

"Endoscopic submucosal dissection (ESD) is an endoscopic procedure that allows dissection of larger colorectal lesions in one piece using endoknives.~The procedure is technically more difficult, much more time-consuming than EMR, mandates multiday hospital admission and has an increased risk of perforation."
