Abstract
Endoscopic mucosal resection (EMR) is the recommended technique for colon polypectomy for nonpedunculated lesions that are >20 mm in size not requiring excision. Dual-channel EMR (DC-EMR) uses an endoscope with two working channels to facilitate easier submucosal injection, snare resection, and clip closure of polypectomy defects. There is also promising early literature indicating that this endoscopic modality can reduce the overall learning curve present for single-channel colonoscopy EMR. This chapter will describe the steps and techniques required to perform DC-EMR, potential complications, recommended postprocedure surveillance, and future directions.
摘要
内镜黏膜切除术（EMR）是推荐用于切除直径>20 mm、无需切除的无蒂结肠病变的息肉切除术技术。双通道EMR（DC-EMR）使用具有两个工作通道的内镜，便于更轻松地进行黏膜下注射、圈套切除以及息肉切除缺损的夹子闭合。也有早期文献表明，这种内镜方式可降低单通道结肠镜EMR存在的整体学习曲线。本章将描述进行DC-EMR所需的步骤和技术、潜在并发症、推荐的术后监测以及未来方向。
