Abstract: Objective To evaluate the significance of colonoscopy with non-mangnifying narrow band imaging (NM-NBI) in predicting the pathological histology of diminutive colorectal polyps. Methods A total of 293 lesions detected by white light colonoscopy were enrolled in this study. These lesions were predicted as neoplastic (adenoma or cancer) or non-neoplastic based on narrow-band imaging international colorectal endoscopic (NICE) classification, which were compared with the results of pathology. The sensitivity, specificity, positive and negative predictive values, and accuracy were evaluated. Results In the differentiation between neoplastic and non-neoplastic lesions, the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy were 92.14%, 81.05%, 81.64%, 91.85% and 86.35%, respectively. Conclusion For most diminutive colorectal polyps, colonoscopy with NM-NBI has potential to replace pathological diagnosis and reduces costs related to post-polypectomy pathologic examinations and polyp removal.

Key words: NICE classification, Diminutive colorectal polyps, Narrow band imaging, Pathological diagnosis
