The bile duct [1] [4] (formerly known as the common bile duct [4]) is a part of the biliary tract. [4] It is formed by the union of the common hepatic duct and cystic duct. It ends by uniting with the pancreatic duct to form the hepatopancreatic ampulla. It possesses its sphincter to enable the regulation of bile flow.
The biliary tree (see below) is the whole network of various sized ducts branching through the liver.. The path is as follows: bile canaliculi → canals of Hering → interlobular bile ducts → intrahepatic bile ducts → left and right hepatic ducts merge to form → common hepatic duct exits liver and joins → cystic duct (from gall bladder) forming → common bile duct → joins with ...
Accessory pancreatic duct 17. Pancreatic duct 18. Small intestine: 19. Duodenum 20. Jejunum 21–22. Right and left kidneys The front border of the liver has been lifted up (brown arrow). [1] Intrahepatic bile ducts compose the outflow system of exocrine bile product from the liver. They can be divided into: [2]
The double duct sign is a radiological finding characterized by the simultaneous dilation of the common bile duct and the main pancreatic duct.This sign is significant because it often indicates an obstruction in the distal bile duct and pancreatic duct, frequently caused by serious underlying pathologies such as pancreatic carcinoma or periampullary tumors. [1]
It is formed by the union of the right hepatic duct (which drains bile from the right functional lobe of the liver) and the left hepatic duct (which drains bile from the left functional lobe of the liver). [3] The duct is about 3 cm long. [4] The common hepatic duct is about 6 mm in diameter in adults, with some variation. [5]
Gallstone disease refers to the condition where gallstones are either in the gallbladder or common bile duct. [5] The presence of stones in the gallbladder is referred to as cholelithiasis , from the Greek chole- ( χολή , 'bile') + lith- ( λίθος , 'stone') + -iasis ( ἴασις , 'process'). [ 1 ]
My heart! At the end when they were sleeping with her, I totally melted! This brought back so many memories for me of bringing home our babies and our Westies meeting them for the first time.
[2] [4] It sometimes join the common hepatic duct at its anterior, posterior, or medial side [4] [3] (in the latter case by passing posteriorly around the common bile duct to join it from the other side). [2] It may spiral around the common hepatic duct before joining it. [4] Very rarely, the cystic duct opens into the duodenum. [3]
