NBI could be a useful additional tool for BE inspection and targeted biopsies, but cannot avoid the need for biopsies following the Seattle protocol. Our results showed that NBI had a significant accuracy in BE assessment for dysplasia prediction, high specificity (>90%), and NPV (>85%), with suboptimal sensitivity. Intraobserver concordance (assessed 6 months after initial test) for mucosal pattern, vascular pattern, and dysplasia prediction was moderate: Κ = 0.56, Κ = 0.47 and Κ = 0.60, respectively. Agreement for mucosal and vascular patterns was 0.39 and 0.30, respectively. Interobserver concordance for dysplasia was weak: Κ = 0.40. low degree of confidence) had better diagnostic accuracy (85.8 vs. Dysplasia prediction done with a high degree of confidence (vs. Positive predictive value and negative predictive value (NPV) were 61.4 and 85.5%, respectively.

Resultsĭysplasia prediction had an accuracy of 81.1%, sensitivity of 48.4%, and a specificity of 91%. Accuracy for dysplasia prediction and intra/interobserver agreement was calculated. Observers were to assign their individual assessment of the mucosal and vascular pattern, and prediction for dysplasia. MethodsĮight observers (4 staff endoscopists and 4 trainee endoscopists) evaluated 100 images selected from an anonymized bank of 470 photographs using the BING classification. We evaluated the diagnostic accuracy for dysplasia prediction using non-magnifying NBI in Evis Exera III processors and high-definition endoscopes using the Barrett International NBI Group (BING) classification, as well as inter/intraobserver agreement for dysplasia prediction and mucosal/vascular patterns. Narrow band imaging (NBI) allows identification of abnormal areas of Barrett’s esophagus (BE) and could facilitate targeted biopsies.
