 BE(Barrett's esophagus)is a metaplastic condition that occurs as a result of gastroesophageal reflux disease. BE is also a precursor to esophageal adenocarcinoma, which, even though still rare in Japan, is one of the most rapidly increasing cancers in Western countries. However, over the past few decades the prevalence of gastroesophageal reflux diseases has significantly increased in Japan. This increase is likely to result in an incremental rise in BE and the associated inherent risk of adenocarcinoma.

 Because of the poor prognosis of late-stage adenocarcinoma in Barrett's esophagus, it is important to detect early neoplasias in BE patients. However, endoscopic identification of early neoplasms remains subjective and not sufficiently reliable, thus, making the targeted therapy extremely difficult.

 During the last decade, newly-developed imaging technologies combined with magnification endoscopy have enabled the identification of early neoplasias in BE patients. This article focuses on such advanced imaging technology, particularly, narrow band imaging, and provides an overview of the technologies, their practical applicability, current status, and future challenges.
