| 【 要旨 】 | 欧米ではこの20 - 30年間に食道癌の組織型が扁平上皮癌から腺癌に逆転している．この現象は欧米では顕著であり，アジア領域では明らかではない． Barrett食道およびBarrett食道癌の疫学を論ずるにあたりもっとも困難な問題点がある．一つにはBarrett食道の定義である．日本食道学会の定義は言葉では明確であるが，実際に円柱上皮化された食道の多くは本来の食道胃接合部から3 cm未満のshort segment Barrett's esophagus (SSBE) と3 cm以上のlong segment Barrett's esophagus (LSBE) の分類が本邦では汎用されている．しかしもっとも多いSSBEと診断される症例のうち，その診断過程，および最近急速にこの領域の早期癌の症例が報告され，現在種々の内視鏡機器を駆使しその実態を検討しているのが本邦の現状である．混乱を防ぐため本邦での詳細な内視鏡診断を基礎にしたBarrett食道およびBarrett食道癌の疫学について述べる． |

| [ Summary ] | Over the past 20 to 30 years, histological diagnoses of esophageal carcinoma have changed from epithelial carcinoma to adenocarcinoma in both Europe and the United States. It has not occured in Asia. There are very difficult problems in discussing the epidemiology of Barrett's esophagus and Barrett's esophageal carcinoma. One problem is due to the definition of Barrett's esophagus. Although the definition by the Japan Esophageal Society is clear, it is common in Japan to classify an esophagus lined with columnar epithelia as having short segment Barrett's esophagus (SSBE) or long segment Barrett's esophagus (LSBE). The length of these epithelia is, shorter than 3 cm and longer than 3 cm, respectively, measured from the original EG junction. However, the most frequently diagnosed SSBE cases are those with rapid increases in early carcinoma. There is currently a trend to investigate patient conditions, including diagnostic processes made using various endoscopic equipment. The epidemiology of Barrett's esophagus and Barrett's epithelial carcinoma, based on through endoscopies are discussed. |
