CANALES SEVILLA, Olivia; MIYAGUI MAEDA, Juan; TAKANO MORON, Juan  y  POQUIOMA ROJAS, Ebert. NBI utility and optical magnification in the differential diagnosis of neoplastic and non-neoplastic colorectal lesions in Peru. Rev. gastroenterol. Perú [online]. 2010, vol.30, n.4, pp. 277-283. ISSN 1022-5129.

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 Kudo’s 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 Kudo’s 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-Emura’s classification. The sensitivity, specificity and diagnostic accuracy was 94.7%, 90.6% and 93.2%, respectively, for Kudo’s 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-Emura’s and Kudo’s Classifications are used.
