Abstract:

对来本院消化科就诊的244例有明显症状的患者依规程进行了~(14)C-尿素呼气试验(~(14)C-UBT),并与胃镜、组织学检查结果相比较。结果表明,在244例中124例HP阳性,其中89例得到证实;另35例因患者拒绝胃镜检查而接受了HP根治性治疗,症状消失或减轻明显,证实其准确率达100%。124例患者经4周治疗后,重复~(14)C-UBT,结果全部转阴。~(14)C-UBT阴性者120例,其中胃镜证实阴性者9例,胃镜取活检示HP阳性者3例,即此3例为~(14)C-UBT假阴性。未发现假阳性病例。由此可知,作为非侵入性方法,~(14)C-UBT简便易行,具有较高的敏感性和特异性,可作为HP诊断的首要方法。
