解剖學術語

胰管Wirsung管(由於存在副胰管,也稱主胰管)是連接胰腺膽總管的管道。為其提供了來自外分泌胰腺胰液,有助於消化

在進食時, 胰液會通過胰管流入消化道中消化蛋白質[1]。若胰管損傷,胰液會外滲到腹腔引發感染腹腔出血併發症, 嚴重的會導致生物體死亡[2][3]

結構

胰管在法特壺腹之前與膽總管匯合,之後兩條胰管在十二指腸大乳頭處穿通十二指腸第二部分的內側。 報告了許多解剖變異,但非常罕見。[4]

副胰管

大多數人只有一根胰管。有些人有額外的副胰管,也稱為聖托里尼管。副胰管可以是功能性的或非功能性的。[5][6]可以單獨打開到十二指腸的第二部分,即背側,通常(在70%的人中)通過十二指腸小乳頭流入十二指腸。[5][6]在另外30%的人中,它排入主胰管,主胰管通過十二指腸大乳頭排入十二指腸。主胰管和副管最終都直接或間接地連接到十二指腸的第二部分('D2',垂直段)。

臨床意義

胰管受壓、令胰液受到阻塞或炎症可能導致急性胰腺炎。梗阻的最常見原因是膽總管中存在膽結石,稱為膽總管結石。阻塞也可能是由於克羅恩病中的十二指腸炎症。[7] 膽結石可能會卡在法特壺腹狹窄的遠端,阻止膽汁和胰液流入十二指腸。膽汁回流到胰管可能引發胰腺炎。[5]CT上胰管頭部大於3mm,體部或尾部大於2mm,一般認為胰管異常擴大。[8]75%至85%的人可通過超聲檢查顯示胰管或部分胰管。[9]

歷史

胰管也稱為Wirsung管。[10]以其發現者德國解剖學家Johann Georg Wirsung(1589–1643)的名字命名。[11]
