The bile duct is a tube that transports bile from the liver to the small intestine. The gallbladder is attached to the bile duct by a small tube called the cystic duct. Bile is collected in the gallbladder between meals and empties into the bile duct through the cystic duct during a meal.
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.
