What it is
Collects bile from the functional left half of the liver (segments II-IV) and runs along the base of the quadrate lobe to the porta hepatis.
Function
Drains bile out of the left liver.
Size
About 2 cm long outside the liver (longer than the right), 3-4 mm wide.
Clinical note
Its long horizontal extrahepatic course makes it the preferred site for surgical bile-duct reconstruction.
