The real-time diagnosis value of NICE classification on neoplastic and non-neoplastic colorectal polyps / 中华消化内镜杂志

ABSTRACT

Objective To investigate the value of NICE classification on real-time diagnosis for neoplastic and non-neoplastic colorectal polyps. Methods The histological type of 107 polypoid lesions from 50 patients detected by colonoscopy was predicted by 4 endoscopic physicians using NICE classification, including 1 chief physician, 2 associate chief physician, and 1 attending physician. Taking pathological result as gold standard, the real-time diagnostic accuracy of NICE classification for neoplastic colorectal polyps was evaluated, and the differences of diagnostic accuracy between the 4 endoscopic physicians were compared. Results Among the 107 polypoid lesions, 49 were neoplastic polyps and 58 were non-neoplastic polyps. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of NICE classification on determination of the histological type of polyps were 81. 6% (40/49), 70. 0% (40/58), 74. 8% ( 80/107) , 70. 0%( 40/58) , and 81. 6%( 40/49) , respectively. There was no statistical difference on the prediction ability between the 4 physicians using NICE classification. Conclusion NICE classification is a feasible method for real-time prediction of histology type of colorectal polyps, and it is undemanding to the qualifications of physicians.
