• BILIARY ATRESIA
• BILIARY CIRRHOSIS
• BILIARY STRICTURE

4

• injury to the bile ducts during surgery for
  gallbladder removal (accounting for 80 of
  nonmalignant strictures)
• pancreatitis (inflammation of the pancreas)
• primary sclerosing cholangitis (an inflammation
  of the bile ducts that may cause pain, jaundice,
  itching, or other symptoms)
• gallstones
• radiation therapy
• blunt trauma to the abdomen

5
BILE DUCT

• A bile duct is any of a number of long tube-like
  structures that carry bile. Bile, required for
  the digestion of food, is excreted by the liver
  into passages that carry bile toward the hepatic
  duct, which joins with the cystic duct (carrying
  bile to and from the gallbladder) to form the
  common bile duct, which opens into the intestine.
  The biliary tree is the whole network of various
  sized ducts branching through the liver.

6
BILIARY ATRESIA

• Biliary atresia is a blockage in the tubes
  (ducts) that carry a liquid called bile from the
  liver to the gallbladder. The condition is
  congenital, which means it is present from birth.
• Causes, Incidence, And Risk Factors
• Biliary atresia occurs when the bile ducts inside
  or outside the liver do not develop normally. It
  is not known why the biliary system fails to
  develop normally.

7
BILIARY CIRRHOSIS

• Definition
• Primary biliary cirrhosis is irritation and
  swelling (inflammation) of the bile ducts of the
  liver, which blocks the flow of bile. This
  obstruction damages liver cells.
• Alternative Names
• PBC
• Causes, Incidence, And Risk Factors
• The cause of inflamed bile ducts in the liver is
  not known. The disease more commonly affects
  middle-aged women

8
BILIARY STRICTURE

• Definition
• 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.
• Alternative Names
• Bile duct stricture

9
CONT. BILIARY STRICTURE

• 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.
• Other causes of this condition include
• Cancer of the bile duct
• Damage and scarring due to a gallstone in the
  bile duct
• Pancreatitis
• Primary sclerosing cholangitis
