摘要
目的：探讨门脉分流指数与Ｃｈｉｌｄ－Ｐｕｇｈ分类的相关性，以了解其对肝硬化的诊断效能．方法：用￣（９９ｍ）Ｔｃ０４－直肠给药法进行门静脉循环ｙ照相，计算门脉分流指数（ＳＩ）．并与胃镜、胃肠钡气双重造影和ＣＴ进行比较。结果：ＳＩ值正常人为７．１％±２．３％，慢性肝炎１２％±３．５％，肝硬化Ｃｈｉｌｄ－ＰｕｓｈＡ分类为２４．５％±１２．５％，Ｂ分类为４８．３％±２１．０％，Ｃ分类为８３．６％±３．９％。若以慢性肝炎均值＋２ｓ即１９％作判别阈，肝硬化患者总阳性率为９０．０％。优于上述其他方法。特异性为１００％。准确率为９４．７％。单纯Ｃｈｉｌｄ－ＰｕｇｈＡ分类，敏感性８０％，特异性１００％，准确率９４．５％。结论：门脉分流指数的测定有可能早期诊断肝硬化，适合临床推广应用。
Objectives: Correlation of portal shunt indexes (SI) with Child-Pugh was made. Their diagnostic efficacy in hepatic cirrhosis was evaluated. Methods: SI were determined through portal circulation imaging by per-rectal 99m Tc 04.Comparison was also made with gastroscopy, double contrast GI series and CT. Results: The SI for normal controls was 7.1 %±2.3%; chronic hepatitis, 12%±3.5%;cirrhosis, Child-Pugh A 24.5%±12.5%,B48.5%±21.0% and C 83.6%±39.%. If the threshold for cirrhosis was set at the mean +2s of chronic hepatitis, namely 19%, the sensitivity was 90.0%, superior to the above other methods, The specificity was 100%, and accuracy 94.7%. If only Child-Pugh A was dealt with, the sensitivity was 80%, specficity 100% and accuracy 94.5%. Conclusions:SI determination is capable in diagnosing cirrhosis at its early stage,
