A prospective randomized comparative study of cold forceps polypectomy by using narrow-band imaging endoscopy versus cold snare polypectomy in patients with diminutive colorectal polyps

In this study, >90% of all DCPs were completely resected by using CFP with NBI evaluation of polypectomy sites, showing noninferiority compared with CSP. However, in polyps measuring >3 mm, CFP failed to show noninferiority versus CSP. CFP appears to be the proper method for resection of DCPs 1 to 3 mm in size if no remnant polyp is visible by NBI endoscopy, but CFP is likely to be insufficient for larger polyps.
