Colorrectal adenomas constitute the best characterized pre-malignancy injury in the development of the cancer in the colon. Colonoscopy with diagnostic and therapeutic aims is essential to prevent the cancer appearance. A prospective, descriptive and observational study was carried out in patients that assisted for colonoscopy at Medical Surgical Research Center from September 2010 to July 2011 The Kudo and the Sano-Emura classifications were used to determine the importance of the cromoendoscopy and the narrow band image at the time to identify histological nature of the polyps in the colon. Sensibility, specificity, positive and negative predictable values and the concordance degree were estimated. The morfology and the dysplasia degree were associated.
