 Esophageal adenocarcinoma, the prevalence of which is increasing in Japan, arises predominantly from Barrett's esophagus(BE). At the Kyoto International Conference, an international consensus was reached that identifying the distal end of the palisade vessels(DEPV)is more useful than identifying the proximal end of the gastric folds(PEGF)for the diagnosis of BE. However, the optimal image-enhanced endoscopy(IEE)modality for DEPV visualization has not yet been established. Through a multicenter collaborative study in which multiple endoscopists objectively evaluated BE images obtained with various IEEs, we demonstrated that red dichromatic imaging(RDI3)and linked color imaging(LCI)provided superior DEPV detectability and reproducibility, with reduced operator dependence. In this article, we review the current status and challenges of endoscopic DEPV diagnosis at the esophagogastric junction, with particular reference to the results of our study.
