慢性胃炎是由多种原因引起的胃粘膜慢性炎症性病变,其发病率随年龄而增加。我国多数是以胃窦为主的全胃炎,后期则以胃粘膜固有腺体萎缩和肠腺化生为主要病理特点。1947年,Schindler根据半屈式胃镜所见和胃粘膜活检结果,将慢性胃炎分为浅表性、萎缩性和肥厚性三类,此种分类法沿用很久。1990年8月在澳大利亚悉尼召开的第9届世界胃肠病学大会上, Chronic gastritis is a chronic inflammatory disease of the gastric mucosa caused by a variety of causes, and its incidence increases with age. The majority of our country is based on gastric antrum-based total gastritis. In the later period, the main pathological features of gastric mucosal atrophy and glandular metaplasia are the main features. In 1947, Schindler classified chronic gastritis into superficial, atrophic, and hypertrophic types based on findings of semi-rigid endoscopy and biopsy of gastric mucosa. This type of classification followed for a long time. At the 9th World Congress of Gastroenterology held in Sydney, Australia, in August 1990,
