摘要 在过去的10年中食管腺癌的发病率呈上升趋势,而患Barrett食管可使食管腺癌发生的危险性大大增加[1].最初认为Barrett食管是指食管内出现柱状黏膜上皮[1].1983年Skinner等[2]将Barrett食管定义为食管远端出现柱状黏膜上皮长度≥3 em.1994年Spechler等[3]研究发现,约18%的患者在食管胃连接处(esophagus-gastric juction,EGJ)的黏膜病理检出杯状细胞,而检出杯状细胞是肠化生上皮的特征,故认为在远端食管(EGJ)、或食管胃鳞、柱状上皮连接处(squamo commnar iunction,SCJ)的浅橙色黏膜中,活检发现肠化生上皮即可诊断为Barrett食管.
