The bile duct is some 6–8 cm long, and normally up to 8 mm in diameter. [4]Its proximal supraduodenal part is situated within the free edge of the lesser omentum.Its middle retroduodenal part is oriented inferiorly and right-ward, and is situated posterior to the first part of the duodenum, and anterior to the inferior vena cava.
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 shows a mildly dilated common bile duct with what appears to be a gallstone (black arrow). The green and blue dots are blood flow, since the exam is done as a Doppler ultrasound to distinguish the bile duct from blood vessels.
Choledochoduodenostomy (CDD) is a surgical procedure to create an anastomosis, a surgical connection, between the common bile duct (CBD) and an alternative portion of the duodenum. [1] In healthy individuals, the CBD meets the pancreatic duct at the ampulla of Vater , which drains via the major duodenal papilla to the second part of duodenum. [ 2 ]
The common hepatic duct is the first part of the biliary tract. [2] 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]
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]
A surgically created passage between the common bile duct and the jejunum in a procedure called a choledochojejunostomy, can be carried out to relieve the symptoms of biliary obstruction as well as allows the bile duct to drain. [5] In infants with biliary atresia, hepatoportoenterostomy is an alternative method of providing bile drainage.
Ultrasound image showing the liver, gallbladder and common bile duct. Medical ultrasound uses high frequency broadband sound waves in the megahertz range that are reflected by tissue to varying degrees to produce (up to 3D) images.
