作者对318例急性胰腺炎患者的352次发作进行了前瞻性研究.除4例外所有急性胰腺炎均经造影剂增强的CT扫描所证实,这4例是在术中或尸检时确诊的.其中67例(19%)入院时血清淀粉酶值正常(即低于160IU/L),这个数字明显地高于通常入院的病人.与血清淀粉酶值升高的急性胰腺炎相比,血清淀粉酶正常的胰腺炎有以下一些特点:(1)酒精源性胰腺炎占多数(58%对33%),(2)酒精源性胰腺炎患者先前有多次发作病史的比例高(0.7对0.4),(3)入院前症状持续时间较长(24对1.5天).虽然血清淀粉
The authors conducted a prospective study of 352 episodes of 318 patients with acute pancreatitis, with all but 4 acute pancreatitis confirmed by contrast-enhanced CT scans, which were confirmed at the time of surgery or autopsy. Serum amylase values were normal (ie, less than 160 IU / L) at admission to hospital in 67 patients (19%), a significantly higher number than patients who normally admitted to hospital.Compared with acute pancreatitis with elevated serum amylase levels, serum amylase Normal pancreatitis has the following characteristics: (1) alcohol-induced pancreatitis accounts for the majority (58% vs 33%), (2) there is a high rate of prior episodes of multiple episodes of alcohol-induced pancreatitis (0.7 vs 0.4) , (3) symptoms persisted longer before admission (24 vs. 1.5 days) .Although serum starches
