Interventions
Standard ESD:Electrocoagulation parameters: endocut Q (effect: 2, duration: 2, interval: 3) for mucosal incision
Submucosal incision: output 40W, effect 2 for submucosal dissection, output 40w, effect 4 for electrocoagulation.
Direct electrocoagulation bleeding is used to incision, or thermal biopsy forceps are
Intermittent Electrocoagulation Group:For small blood vessels or small bleeding points, standard ESD is continuous electrocoagulation with electrosurgery until the vascular eschar stops bleeding, and
