View of the Liver and Gallbladder. Bile empties from the gallbladder into the common bile duct. The common bile duct joins with the pancreatic duct to form the ampulla of Vater, which empties into the duodenum. Before joining the pancreatic duct, the common bile duct tapers to a diameter of â¤ 0.6 cm. The sphincter of Oddi, which surrounds both the pancreatic duct and the common bile duct, includes a sphincter for each duct. Bile does not normally flow retrograde into the pancreatic duct.
Biliary Disorders and Bile Duct Cancer. The biliary duct system is responsible for storing and transporting bile, a yellowish digestive fluid produced in the liver. The bile ducts are the tubes from which bile flows out from the liver. Bile ducts come together like the branches of a tree.The largest duct is called the common bile duct. Before bile is transported to the small intestine to aid in the digestive process, it is collected and concentrated in a storage container called the gallbladder.iliary Stricture. A biliary stricture is a narrowing of the common bile duct. When this happens, bile can back up into the liver, causing abdominal pain, nausea, itching, fever, chills, and jaundice. Strictures can be caused during surgery on nearby tissues, such as the gallbladder.
