Bile duct obstruction

Definition:

Bile duct obstruction is a blockage in the tubes that carry a liquid called bile from the liver to the gallbladder and small intestine.

Alternative Names:

Biliary obstruction

Causes, incidence, and risk factors:

Bile is a liquid secreted by the liver that contains cholesterol , bile salts, and waste products such as bilirubin . Bile salts aid in the digestion of fats. Bile passes out of the liver through the bile ducts and is concentrated and stored in the gallbladder until it is released into the small intestine after a meal to help with fat digestion.

When the bile ducts become blocked, bile accumulates in the liver, and jaundice (yellow color of the skin) develops due to the accumulation of bilirubin in the blood.

The possible causes of a blocked bile duct include:

The risk factors include:

In immunosuppressed patients, the blockage can be caused by infections.
