Stones usually form in the gallbladder, but they may form in the common bile duct. When stones form in the bile duct, the condition is called choledocholithiasis. Also, gallstones may move from the gallbladder into the bile duct and become lodged in the duct, causing pain.

Symptoms
Symptoms of bile duct stones include:

• Severe attacks of pain in the upper right part of the abdomen, which can last for hours
• Jaundice, a yellowing of the skin and whites of the eyes
• Chills and fever
• Nausea and vomiting

Diagnosing bile duct stones
We will ask about your medical history and symptoms. You will have a physical exam, and you may have the following tests:

• Ultrasound
• CT scan
• X-ray with an injected dye for contrast
• Endoscopic retrograde cholangiopancreatography, or ERCP
  This is done using both x-rays and a flexible, lighted tube called an endoscope to see inside the pancreas, liver, gallbladder and bile ducts. A sample of tissue may be removed for tests.  You will receive light sedation for this test.

Treating bile duct stones
Dr. J. Shawn Mallery of the Minnesota Pancreas and Liver Center has developed a unique technique to remove bile duct stones and drain obstructed bile ducts. Other potential treatments include:

• Dissolving the stones with medication
• Surgically removing the stones
• Treatment with endoscopic retrograde cholangiopancreatography, or ERCP.  This is done using both x-rays and a flexible, lighted tube called an endoscope to see inside the bile ducts. The endoscope is used to find the stones and, if possible, remove them through the tube.  You will receive ight sedation for this treatment.
