UNASSIGNED: Background and study aims   No specific endoscopic signs for diagnosing @entity5202 ( @entity5202 ) have been described and very few studies have reported endoscopic signs for @entity2910 ( @entity2910 ). This study aimed to assess the utility of narrow-band imaging magnifying endoscopy (NBI-ME) in predicting @entity5202 / @entity2910 diagnosis before histopathological assessment. @entity1 and methods   Adult @entity1 with @entity1282 and/or food impaction who underwent esophagogastroduodenoscopy followed by NBI-ME and biopsies were included. Three previously reported NBI-ME signs were studied: beige mucosa, dot-shaped intra-epithelial papillary capillary loop (IPCL), and absent cyan vessels. These signs were compared with the histological diagnosis, and studied in @entity1 with and without @entity5202 or @entity2910 . A predictive model containing the NBI-ME signs was analyzed, based on area under the curve (AUC). Results   A total of 137 @entity1 were enrolled. Based on histology 26 were diagnosed with @entity5202 , 26 with @entity2910 , and 85 were control @entity1 with neither diagnosis. Significantly more @entity5202 / @entity2910 @entity1 than control @entity1 showed the NBI signs (P <0.001 for all three signs). Absent cyan vessels had the highest accuracy for differentiation (sensitivity 88%, specificity 92%). A combination of age, dot IPCLs, and absent cyan vessels was highly predictive of @entity5202 / @entity2910 , with an AUC of 0.952. Conclusions   Three NBI-ME signs were found in the majority of @entity1 with @entity5202 / @entity2910 and unlikely to be observed in controls. A combination of two NBI-ME signs and younger age had a higher degree of accuracy. This supports the claim that NBI-ME could be a reliable diagnostic modality for @entity5202 / @entity2910 predictors.
