Abstract:

Colorectal cancer is a highly prevalent malignant tumor globally. Screening by colonoscopy to detect colorectal polyps and removing the polyps can reduce the incidence and mortality of colorectal cancer. The vast majority of colorectal polyps are small polyps with a diameter less than 10 mm.The canceration rate of such polyps is extremely low， and there is a more urgent need for an efficient， safe，and simple endoscopic treatment plan. The cold snare polypectomy does not require electrocoagulation or electrocution， has no damage caused by thermal effects， has almost no perforation， and has an extremely low postoperative bleeding rate， but it has a complete resection rate comparable to that of thermal resection，undoubtedly meeting the above requirements. However， since the cold snare polypectomy is a mechanical cutting， the technique itself also has certain limitations. The recommendations for cold snare polypectomy in the guidelines for colorectal polyp resection have also been continuously updated with the development of technology. This article will review and summarize the latest progress of cold snare polypectomy.
