Total serum amylase activity was found to be significantly elevated postoperatively in 11 (10%) of 110 patients undergoing various surgical procedures. Isoamylase analysis revealed that the rise was chiefly in the pancreatic-type isoamylase in seven of the 11 patients showing postoperative serum amylase elevations; in the other four patients, the elevation occurred principally in the salivary-type isoamylase. These data demonstrate that postoperative hyperamylasemia occurs surprisingly often and that serum amylase activity may rise even when the surgical procedure is extra-abdominal. Moreover, elevation of serum amylase activity after surgery is not necessarily an indication of pancreatitis and may reflect instead a rise in salivary-type isoamylase.
在110例接受各种外科手术的患者中，有11例（10%）术后血清淀粉酶总活性显著升高。同工酶分析显示，在术后血清淀粉酶升高的11例患者中，有7例升高主要是胰腺型同工酶；在另外4例患者中，升高主要发生在唾液型同工酶。这些数据表明，术后高淀粉酶血症的发生频率惊人，即使手术在腹外进行，血清淀粉酶活性也可能升高。此外，术后血清淀粉酶活性升高不一定表明患有胰腺炎，反而可能反映唾液型同工酶升高。
