Prospective Study of Using Novel Bipolar Scissors in Colorectal Endoscopic Submucosal Dissection

"The allocated intervention would be performed under sedation or monitored anaesthesia by experienced endoscopists with at least 50 case experience of colon ESD.~Colon ESD procedure would be performed as per described in the literature. After submucosal injection of solution to create a cushion, mucosal incision and submucosal dissection would be performed with the SydrBlade Flex. Submucosal plane dissection will be performed using the SpydrBlade Flex (BRF, cutting frequency 400kHz, power setting 35W). The exact resection strategy would be according to the endoscopists' preference, including different adjunctive techniques such as countertraction, tunnelling or pocket creation method. Upon completion of ESD, the resultant mucosal defect would be examined for any perforation or bleeding."
