The extrahepatic biliary duct system is subject to a particular bioconstruction to secure its bile transport function. The dominant structure of the bile duct wall is a network of collagen fibres harboring muscle-fibre bundles. The collagen fibres are virtually inelastic, volumes can be changed only by rearranging the network. The ducts show different spatial arrangements of the fibres causing different extents of dilatation during obstruction. Extreme dilatation might cause a rupture of the network, and deficient postoperative retonisation could be the result.
肝外胆管系统具有独特的生物结构以确保其胆汁运输功能。胆管壁的主要结构是一个包含肌纤维束的胶原纤维网络。胶原纤维几乎没有弹性，其容积只能通过重新排列网络来改变。胆管显示出纤维的不同空间排列，这在梗阻期间会导致不同程度的扩张。极度扩张可能导致网络破裂，结果可能是术后恢复张力不足。
