Sclerosing cholangitis
Definition
Sclerosing cholangitis refers to swelling (inflammation), scarring, and destruction of the bile ducts inside and outside of the liver.
Alternative Names
Primary sclerosing cholangitis; PSC
Causes
The cause of this condition is usually unknown.
The disease may be seen in patients who have:
- Autoimmune disorders
- Chronic pancreatitis
- Inflammatory bowel disease (Crohn's disease and ulcerative colitis)
- Sarcoidosis
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
- Infections in the liver, gallbladder, and bile ducts
Symptoms
The first symptoms are usually:
- Fatigue
- Itching
- Yellowing of the skin and eyes (jaundice)
However, some people may have no symptoms.
Other symptoms may include:
- Enlarged liver
- Enlarged spleen
- Loss of appetite and weight loss
- Repeat episodes of cholangitis
Exams and Tests
Some people do not have symptoms, but blood work shows that they have abnormal liver function. The doctor will look for:
- Diseases that cause similar problems
- Diseases that often occur with this condition (especially inflammatory bowel disease)
- Gallstones
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)
Treatment
Medications that may be used include:
- Cholestyramine
- Ursodeoxycholic acid (ursodiol)
- Fat-soluble vitamins (D, E, A, K)
- Antibiotics for infections in the bile ducts
- Medications that quiet the immune system (prednisone, azathioprine, cyclosporine, methotrexate)
Surgical procedures:
- 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 biliary ducts
- Proctocolectomy (for those who have both ulcerative colitis and sclerosing cholangitis)
- Liver transplant
Outlook (Prognosis)
How well patients do varies. The disease tends to get worse over time and sometimes patients develop:
Some patients 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.
Possible Complications
- Bleeding esophageal varices
- Cancer in the bile ducts (cholangiocarcinoma)
- Cirrhosis and liver failure
- Infection of the biliary system (cholangitis)
- Narrowing of the bile ducts (strictures)
- Vitamin deficiencies
