急性胰腺炎的诊断是一件困难的事。多年来,血清淀粉酶测定是诊断急性胰腺炎最常用的实验室检查法。可是血清淀粉酶升高对于急性胰腺炎并不具特异性,临床上严重的急性胰腺炎也可以出现正常的淀粉酶值。有些作者认为,与急性上腹痛有关的轻度血清淀粉酶升高,倾向于排除急性胰腺炎;中度升高提示急性胰腺炎的可能性小于穿孔性溃疡;而很明显的升高则认为是急性胰腺炎特有的指征。但新近的资料未能证明血清淀粉酶升高的诊断意义。 Gambill等认为,尿淀粉酶值比血清淀粉酶值敏感。在他们报导的96例急性胰腺炎病人中,血清淀粉酶超过正常上限的只有36%,而74%的病人尿淀粉酶升高。在淀粉酶升高的病例中,血清淀粉酶
Diagnosis of acute pancreatitis is a difficult task. Over the years, serum amylase assay is the most commonly used laboratory method for the diagnosis of acute pancreatitis. However, elevated serum amylase for acute pancreatitis is not specific, clinically severe acute pancreatitis can also occur normal amylase value. Some authors believe that elevated serum amylase associated with acute upper abdominal pain tends to rule out acute pancreatitis; moderately elevated acute pancreatitis is less likely than perforated ulcer; whereas a clear increase is considered to be Acute pancreatitis specific indications. However, recent data failed to demonstrate the diagnostic significance of elevated serum amylase. Gambill so that the value of urinary amylase is more sensitive than serum amylase. In their report of 96 patients with acute pancreatitis serum amylase exceeded the normal upper limit of only 36%, while 74% of patients urinary amylase increased. In cases of elevated amylase, serum amylase
