Comparison of nice classification for optical diagnosis of colorectal polyps and morphology of removed lesions depending on localisation in colon

Abstract The narrow-band imaging (NBI) International Colorectal Endoscopic (NICE) classification is based on pictures of colon polyps viewed through a spectrum. categorisation utilises staining, surface structure, and vascular patterns to differentiate between hyperplastic adenomatous polyps. It known that accuracy the NICE for colorectal varies depending localisation in colon.The aim this study was compare diagnostic gold standard — morphological analysis determination type lesions colon. A prospective performed an outpatient clinic. 1214 colonoscopies were by two expert endoscopists 475 found 291 patients. overall 80.3%. Optical verification better ascending 93.9%, followed sigmoid 82.1%. Inferior results descending 64.0%. showed could be helpful instrument daily practice For results, proper training should considered. system have role replacement if appropriate achieved.
