Biliary Anatomy

There is significant variation in the biliary tree with the classical description below thought to be present in 60 of the population 2. The right liver has two sections the right anterior section and the right posterior section supplied by the right anterior sectional hepatic artery and the right posterior sectional hepatic artery respectively fig.

The biliary system consists of the organs and ducts bile ducts gallbladder and associated structures that are involved in the production and transportation of bile.

Biliary anatomy. Bile consists of water electrolytes bile acids cholesterol phospholipids and conjugated bilirubin. These structures produce store and release bile to the small intestines where it aids in the digestion of lipids. Bile canaliculi unite to form segmental bile ducts which drain each liver segment.

Intrahepatic bile duct anatomy figure 1 the anterior hepatic duct lies vertical located to the left of the anterior branch of the portal vein. It includes the gallbladder and the intra and extrahepatic biliary tree ie. The biliary tract biliary tree or biliary system refers to the liver gall bladder and bile ducts and how they work together to make store and secrete bile.

Anatomy and functions anatomy of the biliary system. Bile canaliculi hepatic cystic and common bile ducts. The biliary tree also known as the biliary tract or biliary system is comprised of the gallbladder liver and bile ducts.

By convention the biliary tree is divided into intra and extra hepatic bile ducts 1. The plane between these sections is the right intersectional plane. The direction of the posterior duct is more horizontal running superior being epiportal in the hjortsjö crook 2 to the anterior portal branch and joins the anterior duct.

Ductal diameter increases 05 1mm per decade. Both intra and extrahepatic biliary anatomy is complex with the existence of many common and uncommon anatomic variations. The current trend of using mr cholangiography as the modality of choice in the evaluation of biliary diseases and the increasing complexity of hepatic surgical procedures and biliary interventions however necessitate a more widespread and appropriate knowledge of these anatomic variations.

The union of the common hepatic duct and cystic duct forms the common bile duct. Liver and biliary anatomy. Keep in mind that there are many variations of this main scheme.

The common bile duct is usually 7 8cm long and up to 6mm in diameter. The biliary system is the part of the accessory digestive tract that is responsible for producing storing and transporting bile. The transportation of bile follows this sequence.
