Chronic gastritis caused by helicobacter pylori infection课程教案、知识点、字幕

幽门螺旋杆菌感染

引起慢性胃炎

慢性胃炎根据胃粘膜固有腺体

有没有萎缩

可分为慢性浅表性胃炎

和慢性萎缩性胃炎

病因和发病机制

慢性胃炎的病因

最重要的

就是幽门螺旋杆菌感染

幽门螺旋杆菌慢性感染

可以破坏胃黏膜

除了这个原因

还可以长期的慢性刺激

比如说饮酒 吸烟

自身免疫如A型胃炎

致使的恶性贫血

以及含有胆汁的十二指肠液返流

比如说残胃

慢性浅表性胃炎的病理表现

仅仅表现为

胃粘膜慢性炎症细胞浸润

而没有胃粘膜固有腺体的减少

胃镜见胃粘膜充血 水肿

粘膜面可见炎性渗出

慢性萎缩性胃炎的病理表现

根据病因可分为

A型胃炎和B型胃炎

A型胃炎是自身免疫所至

机体产生抗胃底腺壁细胞抗体

和内因子抗体

壁细胞主要分布在胃底和胃体

因此病变主要位于胃底和胃体

而出现抗内因子抗体

影响叶酸代谢而引起恶性贫血

A型胃炎是一种少数的特殊的

外国人容易患的

与自身免疫有关的胃炎

平时与我们关系不大

而B型胃炎主要就是

由幽门螺旋杆菌感染引起

多见于胃窦部

我们中国人多患

我们通常讲的胃炎

不提A型和B型

通常指的就是B型胃炎

由于它好发于胃窦部

以往我们常常把它称为

叫胃窦炎

慢性萎缩性胃炎病理表现

除了粘膜内

有慢性炎症细胞浸润外

还表现为

胃粘膜固有腺体萎缩减少

有时还伴有肠上皮化生

这种空泡状的胃细胞

在肠粘膜上皮才有

这时却在胃粘膜出现了肠上皮

胃镜检查表现为

一 粘膜变薄

有时可透见粘膜下血管

二 皱襞变平

粘膜呈细颗粒状

胃窦胃体分界清楚

三 失去正常胃粘膜的颜色

变得灰白 或者灰红

幽门螺旋杆菌感染

引起慢性胃炎的临床表现

上腹部不适 隐痛

有时发生嗳气 反酸 烧心

恶心 呕吐等症状

如没有正确的治疗病程缓慢

但容易反复发作

就是人们常说的老胃病
