Bile duct stricture
Definition of Biliary stricture
A biliary stricture is an abnormal narrowing of the common bile duct, the tube that moves bile (a substance that helps with digestion) from the liver to the small intestine.
Causes, incidence, and risk factors
A biliary stricture is often caused by surgical injury to the bile ducts. For example, it may occur after surgery to remove the gallbladder.
Signs and tests
The following tests can help diagnose this condition:
The goal of treatment is to correct the narrowing and help bile flow normally from the liver into the intestine. This may involve surgery or less invasive procedures (endoscopic or percutaneous dilation). Depending on the location, if surgery is done, the stricture may be removed and the common bile duct rejoined with the small intestine.
Treatment is usually successful.
