问题 单项选择题 A1/A2型题

关于急性胰腺炎错误的是()。

A.腹痛一般是剧烈的

B.常继发于胆道疾患

C.少数出现轻度黄疸

D.血、尿淀粉酶测定是最常用的诊断方法

E.病变越严重,淀粉酶越增高

答案

参考答案:E

解析:急性胰腺炎时血、尿淀粉酶测定是最常用的诊断方法。血清淀粉酶在发病后数小时开始升高,24小时达高峰,4~5天后恢复正常。尿淀粉酶在发病24小时后开始上升,此后缓慢下降。此两种检测因方法不统一,其正常值也不一致。血尿淀粉酶的高低与病变轻重不一定成正比。严重的坏死性胰腺炎,腺泡破坏严重,淀粉酶值反而不高。血清脂肪酶在发病后24小时升高,血清脂肪酶明显升高(正常23~300U/L)也是比较客观的诊断指标。故答案应选E。
