Abstract

Background: Hepatobilliary surgery is nowadays growing with increasing popularity
throughout the world with advent of newer liver imaging modalities.
Anticipating a wide range of morphological variations of porta hepatis (PH),
a precise understanding is pertinent to preoperative diagnosis, operative procedure
and post-operative outcome of hepatobiliary disease.
Materials and methods: Considering recent interest, present study was undertaken.
One-hundred and ten isolated adult cadaveric livers of unknown age and
sex were dissected to explore detail morphology and morphometry of PH.
Results: Classical picture of PH was observed in 20% liver. The standard representation
of structures was highest in hepatic artery (59.1%) followed by portal vein
(55.5%) and hepatic duct (51.8%). On the basis of structural distribution PH was
described as 16 types. Maximum variable number was found in hepatic artery
followed by portal vein and hepatic duct. In morphometric analysis, transverse
diameter of PH was more than antero-posterior diameter, indicated that PH was
slightly oval in transverse plane. Position of PH was more towards posterior and
slightly right in inferior surface of liver.
Conclusions: Variations of portal anatomy regarding circulatory and biliary dynamics
is worth knowing in successful planning of hepatobiliary surgeries with
least complications.
