Abstract
目的 评估尿胰蛋白酶原2快速测定及尿淀粉酶/尿肌酐比值(U-amy/Ucr)对急性胰腺炎的诊断价值.方法对120例怀疑急性胰腺炎的急腹症患者进行血淀粉酶(B-amy)、尿淀粉酶(U-amy)、尿肌酐(Ucr)尿胰蛋白酶原2快速测定和B超检查.结果120例中53例确诊为急性胰腺炎(AP组),其余67例则为其他原因导致的急腹症(非AP组),40例为正常对照组.B-amy对急性胰腺炎的诊断敏感度为79.2%(分界值为125 U/L),特异性为76.1%;U-amy的敏感性为81.1%(分界值为490 UfL),特异性为73.1%;Uamy/Ucr的敏感性为94.4%,特异性为89.7%;尿胰蛋白酶原2试纸条法的敏感性为94.3%,特异性为95.5%;B超检查的敏感性为88.9%.结论对急性胰腺炎的诊断,U-amy/Ucr的敏感性和特异性较U-amy高,尿胰蛋白酶原2试纸条法的敏感性和特异性优于B-amy。
