 Colorectal polyps are classified into diminutive polyps 5mm in diameter, small polyps 6-9mm in diameter, and large polyps 1cm in diameter. There are several endoscopical treatment methods: cold biopsy forceps polypectomy, cold snare polypectomy, hot biopsy forceps polypectomy, hot snare polypectomy, and endoscopic mucosal resection. Cold polypectomy means mechanical removal of the polyp with snare or biopsy forceps without the use of electrocautery, and hot polypectomy means removal of the polyp with the use of electocautery.
