用放大胃镜及实体镜对93例164块胃粘膜组织的微细结构进行了观察,并与组织病理学对比,结果发现慢性胃炎时粘膜微细形态与正常胃相似,但组织学上有不同程度的炎症、上皮增生、化生及腺体萎缩。溃疡与息肉表现为规则及粗大的C及D型。癌及癌旁组织多呈粗大而不规则的C及D型,组织学上上述病变加重并出现肿瘤结构。 The microscopic structures of 93 cases of 164 gastric mucosa were observed with magnifying endoscopy and solid microscopy, and compared with histopathology. The results showed that the microscopic morphology of mucosa was similar to that of normal stomach in chronic gastritis, but the degree of inflammation was different in histology. Epithelial hyperplasia, metaplasia, and glandular atrophy. Ulcers and polyps showed regular and thick C and D types. Carcinoma and adjacent tissues were mostly thick and irregular C and D type, histologically the above lesions aggravated and the tumor structure appeared.
