Abstract：
The Japan Gastroenterological Endoscopy Society published the second edition of the \"Guidelines for Colorectal Endoscopic Submucosal Dissection/Endoscopic Mucosal Resection\" in 2019 to clarify the indications for colorectal endoscopic mucosal resection (EMR) and endoscopic submucosal dissection and to ensure appropriate preoperative diagnoses as well as effective and safe endoscopic treatment in front-line clinical settings. Endoscopic resection with electrocautery, including polypectomy and EMR, is indicated for colorectal polyps. Recently, the number of facilities introducing and implementing cold polypectomy without electrocautery has increased. Herein, we establish supplementary guidelines for cold polypectomy. Considering that the level of evidence for each statement is limited, these supplementary guidelines must be verified in clinical practice.
摘要：
日本胃肠病学内镜学会于2019年发布了第二版《结直肠内镜黏膜下剥离术/内镜黏膜切除术指南》，以阐明结直肠内镜黏膜下切除（EMR）和内镜黏膜下剥离术的适应症，并确保适当的术前诊断以及在一线临床环境中进行有效和安全的内镜治疗。内镜下电灼术切除,包括息肉切除术和EMR,适用于结直肠息肉。最近,引入和实施无电灼冷息肉切除术的设施数量有所增加。在这里，我们建立了冷息肉切除术的补充指南.考虑到每个陈述的证据水平是有限的，这些补充指南必须在临床实践中得到验证.
