目的 :探讨门脉高压性胃病 (PHG)和门脉高压 (PH)时幽门螺杆菌 (Hp)的感染情况及其Child′s分级与Hp感染的关系 ;方法 :应用1 4 C呼吸试验和尿素酶试验对 3 0例PHG和 3 0例PH病人胃粘膜Hp感染情况检测并与非肝硬化病人进行比较 ;结果 :PHG、PH和对照组Hp感染阳性率分别为 46.67%、50 %和 73 .3 3 % ,经统计学处理对照组明显高于PHG和PH组 (P <0 .0 5) ,Child′sA、B和C级Hp感染率分别为 1 0 / 2 8( 3 5.71 % )、1 1 / 1 9( 57.89% )和 8/ 1 3 ( 61 .54% ) ,经统计学处理 (P >0 .0 5) ;结论 :门脉高压性胃病的发生与Hp感染可能无关 Objective: To investigate the relationship between Helicobacter pylori (Hp) infection and Child’s grading and Hp infection in patients with portal hypertensive gastropathy (PHG) and portal hypertension (PH). Methods: Enzyme assay was used to detect gastric mucosal Hp infection in 30 PHG and 30 PH patients and compared with non-cirrhotic patients. Results: The positive rates of Hp infection in PHG, PH and control group were 46.67%, 50% and 73% respectively. (P <0.05). The Hp infection rates of Child ’s A, B and C were 10.81% (3.71%), (P> 0.05) .Conclusion: The incidence of portal hypertensive gastropathy may not be related to Hp infection
