Endoscopic submucosal dissection in colorectal neoplasia performed with a waterjet system-assisted knife: higher resection rate than conventional technique
Background/Aims Colorectal endoscopic submucosal dissection (ESD) is burdened by its associated high risk of adverse events and long procedure time.Recently, a waterjet-assisted knife was introduced to simplify and speed up the procedure.The aim of this study was to evaluate the efficacy and safety of waterjet-assisted ESD (WESD) compared to that o
