Comparison between Barren's intestinal metaplasia and gastric intestinal metaplasia

巴雷特食管（BE）是一种获得性疾病，与腺癌的高发病率有关。本研究的目的是确定不同类型的Barrett粘膜和胃肠化生粘膜之间的差异。记录Barrett粘膜的精细粘膜图案（小凹图案），并与美蓝染色进行比较。活检标本的组织学，粘蛋白免疫组织学和细胞增殖分析进行有关的小坑模式获得放大内镜。坑模式分为五类。管状或绒毛状小凹不仅具有SCE和美蓝吸收的特征，而且具有Ki标记指数高的肠粘蛋白表型，而其他点状或直线状小凹则不具有SCE，属于胃粘膜表型。长椭圆形小窝型介于这两组之间。通过放大内镜获得的浅表粘膜外观分类不仅反映了组织学特征，而且还反映了粘蛋白表型。

Barrett's esophagus (BE) is an acquired disorder associated with a high incidence of adenocarcinoma. The object of this study was to define the difference among various types of Barrett's mucosa and gastric intestinal metaplastic mucosa. The fine mucosal pattern (pit pattern) of Barrett's mucosa was recorded and compared with methylene blue staining. Histological, mucin immunohistologic, and cell proliferation analyses of biopsy specimens were performed in relation to the pit patterns obtained by magnifying endoscopy. Pit patterns were classified into five categories. Tubular or villous pit patterns were not only characteristics of both SCE and methylene blue absorption but also possessed intestinal mucin phenotype whose Ki-labeling index was high, while other pit patterns, dot or straight pattern, did not have SCE and were categorized into gastric phenotype mucosa. Long oval pit pattern had an intermediate phenotype between these two groups.Classification of superficial mucosal appearance obtained by magnifying endoscopy reflects not only histological features but also mucin phenotypes.
