研究目的:

本研究旨在通过一项前瞻性、多中心、随机、单盲对照试验,系统比较单纯电切联合创面血管电凝止血+金属夹夹闭与传统电凝电切+金属夹夹闭两种EMR术式,在治疗直径≥1 cm结直肠息肉中的安全性和有效性。  

Objectives of Study:

This study aims to systematically compare the safety and efficacy of two endoscopic mucosal resection (EMR) techniques in the treatment of colorectal polyps >=1 cm in diameter through a prospective, multicenter, randomized, single-blind controlled trial. The techniques compared are: EMR using pure cut current combined with targeted coagulation of visible vessels on the wound followed by clip closure versus conventional EMR using blended electrocoagulation current followed by clip closure.
