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, incidence, and risk factors

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

Signs 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:

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

Expectations (prognosis)

How well patients do varies. The disease tends to get worse over time and sometimes patients develop:

• Ascites and varices
• Biliary cirrhosis
• Liver failure
• Persistent jaundice

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.

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
