摘要
目的:探讨食管癌高低发区人群幽门螺杆菌(Helicobacter pylori,Hp)感染与食管贲门粘膜病变关系。方法:食管癌高低发区人群纤维胃镜活检组织行组织病理学观察和Hp观察。分析高低发区人群食管胃病变与Hp感染的关系。结果:低发区人群Hp感染率低于食管癌高发区,但贲门部位Hp感染率高于高发区。结论:贲门部位Hp感染可能对食管上皮起保护作用。
Objective : To explore correlation of Hp infection and esophageal gastric cardia epithelia on the subjects from high-and low-incidence areas for esophageal cancer. Methods : Biopsies to examine for histopathology and Hp infection, to analyze the relation between esophageal and gastric epithelia and Hp infection on subjects from high-and low-incidence areas. Results: Hp infection rate on subjects from low-is lower than those from high-incidence area, but Hp infection in gastric cardia is higher than high-incidence area. Conclusion: Hp infection in gastric cardia might be a protection for esophageal epithelium.
