Cold snare polypectomy(CSP)is one of the endoscopic resection technologies and has been recommended for the removal of diminutive polyps(<5 mm)or noncancerous polyps up to 10 mm in size to reduce the incidence and mortality rate of colorectal cancer.[1]Recently,CSP has made some progress.In this paper,the indications,efficacy,safety,and development of CSP are reviewed.The European Society of Gastrointestinal Endoscopy(ESGE)Clinical Guideline recommends CSP as the preferred technique for the removal of diminutive polyps(≤5 mm),which achieves a high rate of complete resection,low complication rates,and allows adequate tissue sampling for histology(High-quality evidence,strong recommendation).[1]For small polyps(<10 mm),the results of several randomized,single-center trials have shown that CSP can satisfy the requirements for histological eradication,safety,and promptness.[2,3]ESGE also suggests the use of CSP for sessile serrated polyps(SSPs)that are 6 to 9 mm in size because of its superior safety profile(Moderate quality evidence,weak recommendation.)
