A bile duct dilates when an obstruction forms inside it and the duct has to expand to allow bile to travel among the liver, gallbladder, pancreas and small intestine. The first signs of a dilated bile duct range from abdominal pain to dark urine and jaundice, according to Healthline.
The most common cause of common biliary duct dilatation is obstruction due to gallstones, states the Radiology Assistant. Another cause of obstruction besides gallstones is stricture, or narrowing, of the common bile duct.
The bile duct transports bile from the gallbladder through the pancreas and into the small intestine. The bile duct joins the liver to the small intestine. The bile duct is tube-like in appearance.
Bile duct cancer starts in the bile duct. The bile duct is a thin tube that reaches from the liver to the small intestine. There are three different types of bile duct cancer, including intrahepatic, perihilar and distal bile duct cancers.
The function of the common bile duct is to carry bile from the liver and the gallbladder into the duodenum, the top of the small intestine directly after the stomach. The bile it carries interacts with ingested fats and fat-soluble vitamins to enable them to be absorbed by the intestine.
The exact cause of bile duct cancer is unknown, according to Healthline, but scientists implicate mutations in the bile duct cells' DNA. Bile duct cancer is a type of liver cancer that starts in the bile duct cells. The bile duct is a tube that extends from the liver to the small intestines.
If the cause of an enlarged bile duct is an obstructive blockage, it can result in health symptoms such as yellowing of the skin or eyes, itching, fatigue, weight loss, and fever or night sweats. It can also cause abdominal pain, light brown urine, a reduced appetite and clay-colored stools, accordi
