【 要旨 】 食道粘膜が円柱上皮に置き換わった状態を,今日ではBarrett食道あるいはBarrett上皮の言葉が一般的に使われている.本病態が問題視される原因の一つはその生物学的特性にある.すなわち癌発生の高頻度な背景粘膜として捉えられている点である.またその診断・定義・病態については未だ議論のあるところである.混迷の多くの原因は食道胃接合部の同定にある.筆者らは胃側から這い上がる皺襞の消失部位,色調差,縦走血管の肛門側境界を同一とみている.この観点からSSBEに合併したBarrett食道癌を提示し,治療法の考え方を述べた.またBarrett食道が経時的にどのように変化していくのか,生物学的特性と経時的な変化について筆者らの経験を報告した.

[ Summary ] Currently, the condition in which the esophageal mucosa is replaced by a columnar epithelium is generally called Barrett's esophagus (BE) or Barrett's epithelium. One of the sources for questions about this disease is its biological characteristics. In other words, BE is considered to have the type of mucosa that may frequently become a carcinogenic base. In addition, questions remain as to the diagnostic definition, and pathogenesis of this disease. The main reason for these questions is how do we identify the gastroesophageal junction. Our opinions on the disappearing portion of the rugae, which has crept from the stomach, color differences, and longitudinal blood vessels, which are the same as those for the anal boundary. From this standpoint, we discussed a management method for BE by introducing 2 cases of Barrett's carcinoma developed in a short segment of BE (SSBE). We also reported on time-lapse changes in BE, and our experiences with changes in the molecularbiological characteristics of BE.
