Outlook (Prognosis)

Treatment is successful most of the time. Long-term success depends on the cause of the stricture.

Possible Complications

Inflammation and narrowing of the biliary duct may return in some people. There is a risk for infection above the narrowed area. Strictures that remain for a long period can lead to liver damage (cirrhosis).

Symptoms

Symptoms include:

Treatment

The goal of treatment is to correct the narrowing. This will allow bile to flow from the liver into the intestine.

This may involve:

  • Surgery
  • Endoscopic or percutaneous dilation¬†or insertion of stents through the stricture

If surgery is done, the stricture is removed. The common bile duct will be rejoined with the small intestine.

In some cases, a tiny metal or plastic mesh tube (stent) is placed across the bile duct stricture to keep it open.

When to Contact a Medical Professional

Call your health care provider if symptoms recur after pancreatitis, cholecystectomy, or other biliary surgery.
