Sa1942 A HIGH-FREQUENCY GENERATOR FOR ENDOSCOPIC SUBMUCOSAL DISSECTION USING A SCISSORS-TYPE KNIFE FOR EARLY COLORECTAL NEOPLASMS

To reduce the risk of complications from endoscopic submucosal dissection (ESD) using conventional knives, such as dual, flush, or hook knife, we used a scissors-type knife (SB Knife Jr; Akita Sumitomo Bakelite, Japan) to keep an adequate dissection layer while preventing unexpected muscular layer injury. We reported that ESD performed with the SB Knife Jr is technically efficient and safe for treating early colorectal neoplasms, but the longer procedure time is a disadvantage of using the SB Knife.
