研究目的: |
本研究针对直径≥1cm 结直肠粗蒂息肉,其内镜切除后迟发性出血风险高且处理困难。通过前瞻性多中心随机单盲对照试验,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 术式的安全性、有效性,为优化临床治疗方案提供循证依据。 |

Objectives of Study: |
This study focuses on colorectal polyps with thick stalks and diameter >= 1 cm, which are associated with a high risk of delayed bleeding after endoscopic resection and pose challenges in management. Through a prospective, multicenter, randomized, single-blind controlled trial, we compare the safety and efficacy of two EMR procedures: simple electroresection combined with electrocoagulation of wound vessels plus metal clip closure versus traditional electrocoagulation and electroresection plus metal clip closure, so as to provide evidence-based basis for optimizing clinical treatment strategies. |
