Conditions of the application of narrow-band imaging endoscopy for differential diagnostics of colorectal neoplasia (original) (raw)

Abstract

Modern digital technologies make it possible to obtain the additional data for the characteristic of the revealed colorectal lesions and thereby facilitate taking decision as regards the strategies for their real-time treatment. narrow-band imaging endoscopy is used as an alternative to morphological diagnostics for the detection of small-sized polyps. The niCe-classification is one of the most widely applied classifications all over the world. it has been shown that sensitivity of narrow-band imaging endoscopy for the differentiation between hyperplastic and adenomatous polyps amounts to 84,6% (95% Ci 78,35-89,58%) and specificity to 99,2% (95% Ci 95,5-99,9%), 99,3% (95% Ди 96,3-99,9%), with the positive prognostic value being 99,3% (95% Ди 96,3-99,9%), the negative prognostic value 81,9% (95% Ci 74,7-87,7%) and auC for ROC-analysis 0,92 (95% Ci 0,88-0,95). an indispensable condition for the practical application of narrow-band imaging endoscopy for differential diagnostics between hyperplastic and adenomatous polyps is the adequate training of the doctors. One of the forms of such training is master-classes as exemplified by the master class carried out in the framework of the 16 th international conference «high technologies applied in endoscopy of the digestive system» (YeS-2016) held in Yaroslavl. in the Yaroslavl Regional Clinical Oncological hospital, images obtained during colonoscopy are stored to be integrated into the study protocols with the use of the eMiS hardware and software system.
