Efficacy and safety of endoscopic submucosal dissection for submucosal tumors of the colon and rectum

ESD is effective for resection of colorectal SMTs and rarely causes serious adverse events. Tumor location and the experience of endoscopists influence the complete resection rate and the development of serious adverse events. ESD is feasible for large tumors and tumors in the muscularis propria, but this is associated with relatively high risks of adverse events.
