为评估幽门螺杆菌(Hp)感染和胃炎在无症状成人中的发病率,作者对健康志愿者30名作上消化道内镜检查。方法和结果活检标本取自胃体和胃窦粘膜,并用光镜检查胃粘膜炎症和Hp感染的存在。内镜检查发现,12例有胃炎征象,其中仅7例得到组织学证实。内镜检查正常的病例中,组织学检查17例正常,13例(43％)活检标本发现炎症存在,10例胃体和幽门前区均有炎症存在 To assess the incidence of Helicobacter pylori (Hp) infection and gastritis in asymptomatic adults, the authors performed upper gastrointestinal endoscopy on 30 healthy volunteers. Methods and Results Biopsy specimens were taken from the gastric and antral mucosa and examined for the presence of gastric mucosal inflammation and Hp infection by light microscopy. Endoscopy revealed that 12 had signs of gastritis, of which only 7 were histologically confirmed. Of the normal endoscopy cases, 17 were histologically normal and 13 (43%) biopsy specimens were found to be inflamed, while 10 were corpus and pyloric areas with inflammation
