•Normal digestive system
1. Chronic Gastritis
2. Helicobacter pylori Gastritis
3. Autoimmune gastritis
4. Peptic ulcer
5. Gastric Adenocarcinoma
6. Inflammatory bowel disease
- Crohn’s disease
- Ulcerative colitis
7. Adenocarcinoma
1. Chronic Gastritis 慢性胃炎
• Presence of chronic inflammatory changes in the mucosa黏膜存在的慢性發炎變化
• Most common cause is infection with the bacillus Helicobacter pylori.
- Autoimmune gastritis 自體免疫性胃炎 -->. the most common cause of atrophic gastritis
萎縮性胃炎
- association with pernicious anemia 與惡性貧血有關
- Toxic, as with alcohol and cigarette smoking 有毒,如飲酒和吸煙
, - Presents less than 10% of cases of chronic gastritis 佔慢性胃炎病例的不到 10%
- most common form of chronic gastritis in patients without H. pylori infection.
也是未感染幽門螺旋桿菌的患者中最常見的慢性胃炎形式
Complication of chronic Gastritis
•Peptic ulcer Disease (PUD) 消化性潰瘍
•Mucosal atrophy and intestinal metaplasia 黏膜萎縮及腸化生
-Increase the risk of adenocarcinoma, especially in autoimmune gastritis
•Dysplasia 發育不良
•Gastric cystica 胃囊腫
Gastric acidity: gastric juice (acid ~pH 2) -->. damage stomach tissue
Peptic enzymes: enzyme will digest (kill) your own cells
Mucus: secrete mucus cell (neutralize the gastric juice), renew very fast
