This network of ducts is part of the biliary system. When one or more of the ducts that transport bile become blocked, it is known as a bile duct obstruction.
It is also commonly referred to as biliary obstruction. A bile duct obstruction can lead to bile accumulating in the liver and a buildup of bilirubin in the blood. Gallstones are a common cause of bile duct obstruction. They can form when there is a chemical imbalance in the gallbladder. If they are large enough, they may block a bile duct as they pass through the biliary system. Bile duct cancer refers to all cancers that develop within the biliary system. The resulting tumors may block a bile duct.
Pancreatic cancers can cause a bile duct obstruction if the tumor enters the intestine. Cancers that have started elsewhere in the body may also spread to the biliary system where they can cause an obstruction. A blockage can sometimes result from an injury that occurs during a medical procedure, such as gallbladder surgery or endoscopy.
Choledochal cysts can sometimes cause bile duct obstructions. These cysts, which are sections of an enlarged bile duct, are congenital, meaning some people are born with them.
They are also rare. Symptoms of a blocked bile duct may come on suddenly, or a person may start to notice them slowly over many years. Some of the symptoms are related to the obstruction, causing liver products to back up and leak into the bloodstream. Others are caused by the bile duct not being able to deliver the digestive juices that the gut needs.
This can stop the body from absorbing some fats and vitamins properly. When bilirubin is unable to enter the bile, it builds up in the body and can cause jaundice. The lack of bilirubin in the bile can also cause dark urine and pale stools. Liver damage can cause similar symptoms to biliary obstruction, so the doctor may also ask about alcohol or drug use as well as sexual practices.
A doctor may also carry out blood tests. The following results would suggest a biliary obstruction:. If blood tests suggest a biliary obstruction, the doctor may recommend one of the following imaging methods to confirm the diagnosis:. Doctors can usually remove gallstones using an endoscope during an ERCP. The tumor is either removed, or the obstruction is cleared by dilating the obstruction and adding a tube for drainage.
Symptoms of Bile Duct Obstruction Bile duct obstruction has certain symptoms that are notable when they occur together, but can be hard to diagnose in isolation. Causes of Bile Duct Obstruction Bile duct obstruction can be caused by several different factors, however the most common of them is gallstones. More often than not, these tumors originate in the pancreas. For this reason, bile duct obstruction is a potential symptom of pancreatic cancer.
