过去10年中涌现了很多研究胰腺的方法,其中不少并无突出的临床价值,故在急性胰腺炎病程中不宜任意或过多使用。急性胰腺炎的诊断血清淀粉酶测定仍为最广泛应用的诊断试验,但在发病后数天测定可能错过峰值。另外,高脂血症可影响测定结果;在这种情况下,如尿淀粉酶超过750 IU/L则有助于急性胰腺炎的诊断。一些作者认为血淀粉酶不高时,最有价值的试验为淀粉酶与肌酐清除率的比率,比率>6%有助于诊断。据认为,这一测定有三个优点:1.比值升高持续的时间比血淀粉酶长数天;
In the past 10 years, there have been many methods of studying the pancreas, many of which have no outstanding clinical value. Therefore, they should not be used arbitrarily or excessively in the course of acute pancreatitis. Diagnosis of Acute Pancreatitis Serum amylase assays are still the most widely used diagnostic test, but peaks may be missed in the days after onset. In addition, hyperlipidemia can affect the outcome of the test; in this case, a urine amylase of more than 750 IU / L contributes to the diagnosis of acute pancreatitis. Some authors consider the most valuable test when the amylase is not high, as the ratio of amylase to creatinine clearance, at a rate of> 6%, is useful for diagnosis. It is believed that this assay has three advantages: 1. The ratio increases for a number of days longer than blood amylase;
