Choledocholithiasis is the presence of at least one gallstone in the common bile duct. The stone may be made up of bile pigments or calcium and cholesterol salts.
About 1 in 7 people with gallstones will develop stones in the common bile duct. This is the small tube that carries bile from the gallbladder to the intestine.
Risk factors include a history of gallstones. However, choledocholithiasis can occur in people who have had their gallbladder removed.
Often, there are no symptoms unless the stone blocks the common bile duct. Symptoms may include:
Exams and Tests
Tests that show the location of stones in the bile duct include the following:
- Abdominal CT scan
- Abdominal ultrasound
- Endoscopic retrograde cholangiography (ERCP)
- Endoscopic ultrasound
- Magnetic resonance cholangiopancreatography (MRCP)
- Percutaneous transhepatic cholangiogram (PTCA)
Your doctor may order the following blood tests:
The goal of treatment is to relieve the blockage.
Treatment may involve:
- Surgery to remove the gallbladder and stones
- ERCP and a procedure called a sphincterotomy, which makes a surgical cut into the muscle in the common bile duct to allow stones to pass or be removed
Blockage and infection caused by stones in the biliary tract can be life-threatening. Most of the time, the outcome is good if the problem is detected and treated early.
