A novel thin wire snare‐assisted en bloc cold snare endoscopic mucosal resection of a colonic adenoma 10‐14 mm in size

Abstract

Cold snare polypectomy (CSP) is performed as a standard technique for small colorectal polyps. However, CSP for 10‐14 mm colorectal polyps was reported to have limitations in terms of the histological margin,¹ and CSP is not indicated for polyps ≥ 10 mm.² Recently, piecemeal cold snare endoscopic mucosal resection (CS‐EMR), which combines submucosal injection and CSP technique, has been used for colorectal polyps ≥ 10 mm.³ However, the feasibility of en bloc CS‐EMR for 10‐14 mm colorectal adenomas is unclear.
