Validation of treatment algorithm based on the Japan narrow-band imaging expert team classification for sub-centimeter colorectal polyps

Background and study aims  Although cold polypectomy (CP) is widely used for colorectal polyps Patients and methods  Consecutive patients with at least one colorectal non-pedunculated polyp   2B lesions were removed by EMR in compliance with the algorithm. Polypectomy outcomes were compared between the compliant and non-compliant groups. Histological outcomes were analyzed in accordance with JNET classification. Results  Post-polypectomy bleeding rate in the compliant group (0 %) was lower than that in the non-compliant group (0.53 %, P P P  = 0.012), and the lesion with free resection margin (91 % vs 64 %, P Conclusion  This study indicated our algorithm would be valid: CP is suitable for most polyps
