胰管
胰管或Wirsung管(由于存在副胰管,也称主胰管)是连接胰腺和胆总管的管道。为其提供了来自外分泌胰腺的胰液,有助于消化。

在进食时, 胰液会通过胰管流入消化道中消化蛋白质[1]。若胰管损伤,胰液会外渗到腹腔引发感染、腹腔出血等并发症, 严重的会导致生物体死亡[2][3]。
临床意义
胰管受压、令胰液受到阻塞或炎症可能导致急性胰腺炎。梗阻的最常见原因是胆总管中存在胆结石,称为胆总管结石。阻塞也可能是由于克罗恩病中的十二指肠炎症。[7] 胆结石可能会卡在法特壶腹狭窄的远端,阻止胆汁和胰液流入十二指肠。胆汁回流到胰管可能引发胰腺炎。[5]CT上胰管头部大于3mm,体部或尾部大于2mm,一般认为胰管异常扩大。[8]75%至85%的人可通过超声检查显示胰管或部分胰管。[9]
