A biliary obstruction is a digestive and excretory disorder characterized with the obstruction of the bile ducts. The condition arises as a result of blockage involving the bile ducts, liver, gallbladder, pancreas and the small intestine. It is more prevalent among women than men. Intrahepatic and extrahepatic ducts are the two types of biliary obstruction.

It must be noted that an untreated biliary obstruction may lead to several liver diseases which may be fatal. The bile is important in the removal of waste products from the body.




The common causes of obstructed bile duct include:
Bile ducts inflammation
Enlarged lymph nodes
Tumor growth in the bile ducts, pancreas
Gallbladder damages or injuries
Liver damage
Complications following liver surgery
Trauma or stress
Stricture of the bile ducts
Hepatitis and other liver infections
Cirrhosis severe liver damage



Predisposing risk factors

Magnetic resonance cholangiopancreatography (MRCP)
Endoscopic retrograde cholangiopancreatography (ERCP)
