 BE(Barrett's esophagus)is a precursor of esophageal adenocarcinoma, which, although still rare in Japan, is one of the most rapidly increasing cancers in Western countries. However, the prevalence of gastroesophageal reflux disease has significantly increased over the past few decades in Japan, possibly leading to an incremental rise in BE and the associated inherent risk of adenocarcinoma.

 Given the poor prognosis of late-stage BEN(BE-related neoplasms), it is important to detect BEN at an early stage. However, endoscopic identification of eBEN(early-stage BEN)is to date not reliable and inaccurate, making targeted biopsy only by conventional endoscopy extremely difficult. During the last decade, newly developed imaging technologies, such as narrow band imaging combined with magnification endoscopy, have enabled early identification of eBEN lesions. This article focuses on how to accurately detect and diagnose eBEN using magnification endoscopy.
