Treatment

The goal of treatment is to correct the narrowing so bile flow normally from the liver into the intestine.

This may involve:

  • Surgery
  • Endoscopic or percutaneous dilation

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

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