Sclerosing cholangitis refers to swelling (inflammation), scarring, and destruction of the bile ducts inside and outside of the liver.
Primary sclerosing cholangitis; PSC
The cause of this condition is usually unknown.
The disease may be seen in people who have:
- Autoimmune disorders
- Chronic pancreatitis (inflamed pancreas)
- Inflammatory bowel disease (Crohn disease and ulcerative colitis)
- Sarcoidosis (a disease that causes inflammation in various parts of the body)
Genetic factors may also be responsible. Sclerosing cholangitis occurs more often in men than women. This disorder is rare in children.
Sclerosing cholangitis may also be caused by:
- Choledocholithiasis (gallstones in the bile duct)
- Infections in the liver, gallbladder, and bile ducts
The first symptoms are usually:
- Yellowing of the skin and eyes (jaundice)
However, some people have no symptoms.
Other symptoms may include:
Exams and Tests
Even though some people do not have symptoms, blood tests shows that they have abnormal liver function. Your health care provider will look for:
- Diseases that cause similar problems
- Diseases that often occur with this condition (especially inflammatory bowel disease)
Tests that show cholangitis include:
- Abdominal CT scan
- Abdominal ultrasound
- Endoscopic retrograde cholangiopancreatography (ERCP)
- Liver biopsy
- Magnetic resonance cholangiopancreatography (MRCP)
- Percutaneous transhepatic cholangiogram (PTC)
Blood tests include liver enzymes (liver function tests).
Medicines that may be used include:
- Cholestyramine (such as Prevalite) to treat itching Ursodeoxycholic acid (ursodiol) to improve liver function
- Fat-soluble vitamins (D, E, A, K) to replace what is lost from the disease itself
- Antibiotics to treat infections in the bile ducts
- Medicines to quiet the immune system (such as prednisone, azathioprine, cyclosporine, or methotrexate)
These surgical procedures may be done:
- Inserting a long, thin tube with a balloon at the end to open up narrowing (endoscopic balloon dilation of strictures)
- Placement of a drain or tube for major narrowing (strictures) of bile ducts
- Proctocolectomy (removal of colon and rectum, for those who have both ulcerative colitis and sclerosing cholangitis)
- Liver transplant
How well people do varies. The disease tends to get worse over time, and sometimes people develop:
- Ascites (buildup of fluid in the space between the lining of the abdomen and abdominal organs) and varices (enlarged veins)
- Biliary cirrhosis (inflammation of the bile ducts)
- Liver failure
- Persistent jaundice
Some people develop infections of the bile ducts that keep returning.
People with this condition have an increased risk of developing cancer of the bile ducts (cholangiocarcinoma). They should be checked regularly with a liver imaging test and blood tests. People who also have inflammatory bowel disease may have an increased risk of developing cancer of the colon or rectum and should have periodic colonoscopy.
Complications may include:
- Bleeding esophageal varices
- Cancer in the bile ducts (cholangiocarcinoma)
- Cirrhosis and liver failure
- Infection of the biliary system (cholangitis)
- Narrowing of the bile ducts
- Vitamin deficiencies
