对 2 1例含异位胃粘膜的美克尔憩室及 12例小肠标本进行 HE和 Mowry阿尔新蓝过碘酸雪夫反应 ,观察憩室内异位胃粘膜和小肠粘膜的病理改变 ,并将肠壁基底膜长度为 410μm范围憩室内各部位小肠粘膜杯状细胞的数目与小肠标本进行了比较。结果显示 ,异位胃粘膜均起始于憩室顶端向基底部延伸 ,出血好发于憩室内小肠粘膜端 ,病变以憩室内异位胃粘膜与小肠粘膜交界处为重。在异位胃粘膜存在的情况下 ,憩室内小肠粘膜的杯状细胞可向分泌中性粘液的改变
21 cases of ectopic gastric mucosa with Meckel diverticulum and 12 cases of small intestine specimens HE and Mowry alchemy periodic acid Schiff response to observe ectopic gastric mucosa and small intestine diverticulum pathological changes and the intestinal wall The number of small intestinal mucosa goblet cells in various parts of the diverticulum in basement membrane length 410μm was compared with that in small intestine. The results showed that ectopic gastric mucosa began in the diverticulum to the basal part of the top extension, bleeding occurs in the small intestine mucosa of the diverticulum, the lesion to diverticula outside the ectopic gastric mucosa and small intestine junction as the most important. In the presence of ectopic gastric mucosa, goblet cells in the small intestine mucosa of the diverticulum may alter the secretion of neutral mucus
