Despite the current sterile techniques used for all procedures, infections are always a possibility. The treatment options will vary depending on the location of the infection. Infections can range from very minor skin infections that are only treated with antibiotics and possibly a few extra days in the hospital to a very major infection that may require a repeat ERCP or sometimes surgery. Loss of life is a rare possibility.
The bile ducts are a common place for an infection to occur especially if bile cannot drain well after the procedure. If an infection does develop your doctor will discuss the treatment options and expected outcomes with you.
