David经过统计学处理选出下面五项有诊断意义的指标。 1.年龄>50,阳性率82％。 2.年龄>50,女性,阳性率82％。 3.AKP>300IU/L,阳性率86％。 4.GPT>100IU/L,阳性率89％。 5.血清淀粉酶>4000IU/L,阳性率73％。 病人具有上述五项指标的3项者,胆石性胰腺炎的诊断准确率为86％,具有4项指标者为95％,具有5项指标者为100％。故有3项指标以上者,可拟诊为胆石性胰腺炎。临床表现和生化指标对胆石性胰腺炎特异性不如B超也不适用于所有胰腺炎病人,但对B超诊断胆石性胰腺炎有怀疑者,胆囊内有微小结石及B超不易看到的胆总
David statistically selected the following five diagnostic criteria. 1. Age> 50, the positive rate of 82%. 2. Age> 50, female, the positive rate of 82%. 3.AKP> 300IU / L, the positive rate of 86%. 4.GPT> 100IU / L, the positive rate of 89%. 5. Serum amylase> 4000IU / L, the positive rate of 73%. Patients with the above five indicators of the three who diagnosed gallstone pancreatitis 86% accuracy, with 4 indicators were 95%, with 5 indicators were 100%. Therefore, there are three indicators above, may be diagnosed with gallstone pancreatitis. Clinical manifestations and biochemical indicators of gallstone pancreatitis specificity is not as good as B-also does not apply to all patients with pancreatitis, but the diagnosis of B-type gallstone pancreatitis have suspected gallbladder with small stones and B-difficult to see the gall bladder total
