The right hepatic duct is a small tube located in the liver's biliary network. Together, the right and left hepatic ducts form the common hepatic duct. Hepatic means liver in Greek. The right hepatic duct's function is to drain bile from the liver's internal right and caudate lobes. The right hepatic duct is an extrahepatic bile duct, which extends outside of the liver; hence, it allows bile to be carried from the liver to the small intestine to aid in digestion. Bile contains bile salts and cholesterol, which help digest fats. Patients who are experiencing problems with their right hepatic artery may require a right hepatic lobectomy, which involves the right hepatic duct. Once the gallbladder is removed, the right hepatic duct is easier to see and is divided and double-sutured to expose the variable arterial supply. Some patients may also experience a right hepatic duct diverticulum, which is basically when bile gets stuck and forms sludge in the small tube.
