目的 探讨放大内镜用于胃黏膜幽门螺杆菌 (H .pylori)感染可视性诊断的可能性。方法 对 14 0例慢性胃炎患者应用OlympusGIFQ 2 4 0Z型放大内镜对胃黏膜微细结构形态进行观察和分型 ,以快速尿素酶试验和Warrthin Starry银染色检测H .pylori感染 ,分析两者之间的相互关系。结果 将胃窦黏膜小凹形态分为B型 (短棒状 )、C型 (树枝状 )、D型 (斑块状 )及E型 (绒毛状 ) 4种基本类型 ,C型小凹黏膜的H .pylori感染率 (5 8 3% ,2 1/ 36 )明显高于B型小凹黏膜 (36 3% ,2 9/ 80 ) (P <0 0 5 ) ,H .pylori阳性黏膜胃小凹常伴有开口扩张、表面发红等表现。胃体下部集合静脉形态可分为R(规则 )型、I(不规则 )型及D(消失 )型 ,3种类型的H .pylori感染率分别为12 2 % (9/ 74 )、6 0 % (9/ 15 )和 84 3% (4 3/ 5 1) ,R型与I型或D型比较有显著性差异 (P <0 0 1)。结论 放大内镜对胃黏膜H .pylori感染有一定可视性诊断价值
Objective To investigate the feasibility of magnifying endoscopy for the diagnosis of gastric mucosal H. pylori infection. Methods Forty-four patients with chronic gastritis were examined with Olympus GIFQ 240 L type magnifying endoscope to observe the microstructure of gastric mucosa. The rapid urease test and Warrthin Starry silver staining were used to detect H. pylori infection. The relationship between. Results The mucosa of gastric antrum were divided into four basic types: type B (short rod), type C (dendritic), type D (plaque) and type E (villous) The infection rate of Pylori (53.3%, 21/36) was significantly higher than that of type B (36.3%, 29/80) (P <0.05). The positive rate of H. pylori positive gastric mucosa With the opening expansion, the surface redness and other performance. The morphology of inferior vena cava veins could be divided into R (regular) type, I (irregular) type and D (disappearance) type. The infection rates of H.pylori in the three types were 12 2% (9/74), 60 % (9/15) and 84 3% (4 3/5 1) respectively. There was significant difference between type R and type I or type D (P <0.01). Conclusion Magnifying endoscopy has a certain diagnostic value of H. pylori infection in gastric mucosa
