摘要 目的探讨儿童幽门螺杆菌感染及胃癌的关系。方法内镜下胃黏膜活检取材,应用常规固定,石蜡切片HE,HP染色镜检,1例加染PAS及AE1/AE3,CK8,KP-1,LCA,SMA免疫标记,结合临床进行病理学观察。结果216例胃黏膜活检病理诊断:轻度慢性浅表性胃炎89例,中度慢性浅表性胃炎92例(1例胃腺癌),重度慢性浅表性胃炎35例,后两组均各有4例为活动性胃炎。190例石蜡切片加印片HP染色:中、重度慢性浅表性胃炎HP阳性检出率明显高于轻度胃炎者(P=0.0281),差异有统计学意义;而临床诊断与活检病理诊断比较,差异无统计学意义(P=0.25);通过特染及酶标确诊胃腺癌合并HP重度感染1例(有便血史2个月患儿)。结论①儿童重、中度慢性浅表性胃炎HP阳性检出率明显高于轻度慢性浅表性胃炎,三者比较差异有显著性(P=0.0281)。而且1例中度慢性浅表性胃炎有胃腺癌患儿为HP重度感染,提示HP感染与胃炎程度及胃腺癌确有关系,但三者确切关系有待进一步探讨;②活检标本石蜡切片HP染色加新鲜胃黏膜印片HP染色将提高HP阳性检出率,本组提高7%;③对有便血患儿应警惕胃癌可能,必要时及早胃镜检查加活检以便及时治疗HP感染及早期预防、早期诊断、早期治疗胃癌。
