INTRODUCTION: The Narrow Banding Image NBI-Colonoscopy and Optical Magnification is a useful method for evaluation in vivo of capillary pattern and pit pattern of colorectal polyps. AIM: To evaluate the usefulness of NBI and Optical Magnification in differential diagnosis of colorectal polyps using Sano-Emura and Kudos Classifications. METHODS: Between january and may 2010, 86 colonoscopies were analyzed by two colonoscopists; 136 polyps were found and histologically analyzed. All polyps under 10 mm (119) were evaluated in accord with Sano-Emura and Kudos classifications; data was analyzed together with an epidemiologist in cancer. RESULTS: The sensitivity, specificity and diagnostic accuracy was 97.3%, 90.7% and 94.9%, respectively, for Sano-Emuras classification. The sensitivity, specificity and diagnostic accuracy was 94.7%, 90.6% and 93.2%, respectively, for Kudos Classification. CONCLUSIONS: The colonoscopy with NBI and Optical Magnification is an effective, reliable and simple method for Colorectal neoplastic and non - neoplastic differential diagnosis when Sano-Emuras and Kudos Classifications are used.
