Early Gastric Cancer, Endoscopic Resection
Conditions
Keywords
Endoscopic resection, Early gastric cancer
Brief summary
Endoscopic submucosal dissection (ESD) is a technically difficult and time-consuming procedure. Several water-jet knives have been developed to address this issue. The aim of this study was to develop a new ESD method using continuous low-pressure water injection at 1-2 atmosphere with a tip-injected electric knife while dissection simultaneous cutting, dissection, electrocoagulation, and hemostasis, which was so called as water-injecting ESD (W-ESD) to treat early gastric cancer and compare the efficacy and safety with conventional methods.
