With the development and maturation of endoscopic management, endoscopic mucosal resection (EMR), endoscopic submucosal dissection (ESD), submucosal tunneling endoscopic resection (STER) and laparoscopic-endoscopic cooperative surgery (LECS) show absolute advantages in minimal invasion and functional preservation in the treatment of colorectal neoplasms. More and more endoscopic managements are carried out to treat colorectal neoplasms. The aim of this article is to summarize the application of endoscopic management for colorectal neoplasms.
