胃小凹的特征性改变,尤其是D型、E型胃小凹的出现极大地提示胃黏膜萎缩的形成。B型到E型4种基本形态胃小凹与肠上皮化生的严重程度之间呈明显正相关,E型是肠化生的特征性改变。幽门螺杆菌是导致胃黏膜萎缩的关键因素。本文综合近几年有关放大内镜诊断萎缩性胃炎的文章,总结既往研究结果,并进行整理和分类。
The characteristic changes of the foveola, especially the appearance of D-type and E-type foveola, greatly prompted the formation of gastric mucosa atrophy. There were significant positive correlations between the four basic forms of gastric pits from type B to type E and the severity of intestinal metaplasia. Type E was the characteristic change of intestinal metaplasia. Helicobacter pylori is the key factor leading to gastric mucosal atrophy. This article combines the recent years on the magnifying endoscopy diagnosis of atrophic gastritis articles, summarize the results of previous studies, and to organize and classification.
