Bile Duct Obstruction: Causes, Symptoms, and Treatment

What kind of doctor treats Bile Duct Obstruction?
Bile duct obstruction is usually treated by a gastroenterologist, a doctor who treats the digestive system. Some people need a surgeon as well. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is bile duct obstruction?
Bile duct obstruction is a blockage in the tubes that carry bile from the liver to the gallbladder and small intestine. Bile is a liquid made by the liver. It holds bile salts, which help your body break down fats, plus cholesterol and waste products. When the ducts get blocked, bile builds up in the liver. A waste product called bilirubin then builds up in the blood and causes jaundice, a yellow color of the skin.
Gallstones are the most common cause. A gallstone can slip out of the gallbladder and lodge in the main bile duct. Other causes include swelling of the bile ducts, narrowing from scarring, injury from gallbladder or liver surgery, tumors of the bile ducts or pancreas, cysts, enlarged lymph nodes near the liver, and liver flukes, which are parasitic worms. Infections can also block the ducts, mostly in people with weak immune systems.
Symptoms
Symptoms may include:
- Jaundice, or yellow skin color.
- Dark urine.
- Clay-colored or pale stools.
- Itching.
- Pain in the upper right side of the belly.
- Fever.
- Nausea and vomiting.
Causes and who gets it
You have a higher risk of a blocked bile duct if you have had gallstones, long-lasting pancreatitis, or pancreatic cancer. Recent belly injury, recent bile duct surgery, and bile duct cancer also raise the risk. A history of gallstones is the leading cause worldwide.
How doctors diagnose it
Doctors examine you and feel your belly. Blood tests often show a high bilirubin level, high liver enzymes, and high levels of other liver chemicals. An abdominal ultrasound, a painless scan using sound waves, is usually the first imaging test. Other tests include a CT scan, an MRI scan of the bile ducts called MRCP, and ERCP. ERCP stands for endoscopic retrograde cholangiopancreatography. It is a test where a doctor passes a lighted tube down the throat to see and treat the bile ducts.
Treatment
The goal of treatment is to relieve the blockage. Doctors can often remove stones with an endoscope during an ERCP. In some cases, surgery is needed to bypass the blockage. The gallbladder is usually removed if gallstones caused the blockage. Doctors give antibiotics if they suspect an infection. If cancer caused the blockage, the duct may need to be widened and a small tube called a stent may be placed to hold it open and drain the bile. Most blockages can be treated with endoscopy or surgery.
When to see a doctor
Contact your doctor if you notice a change in the color of your urine or stools, develop jaundice, or have belly pain that does not go away. Call 911 or go to the emergency room if you have fever, jaundice, and belly pain. That mix can signal cholangitis, a dangerous infection of the bile ducts that can be fatal if not treated promptly. A long-lasting blockage can also cause lasting liver disease.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either can arrange the first tests for jaundice or belly pain, follow your progress after treatment, and coordinate your care with a gastroenterologist or surgeon.
Common questions
Can a blocked bile duct go away on its own?
Sometimes a small stone passes on its own, and liver tests moving back toward normal suggest that this happened. But you should never wait on a suspected blockage, because untreated blockage can cause life-threatening infection. See a doctor promptly.
What is the most common cause of bile duct obstruction?
Gallstones. Stones that leave the gallbladder can get stuck in the common bile duct, the main drainage tube. Swelling, scarring, surgery injury, tumors, and parasites are other causes.
What is ERCP?
ERCP stands for endoscopic retrograde cholangiopancreatography. The doctor passes a lighted, flexible tube through the mouth into the small intestine to reach the bile duct opening. Dye shows the ducts on an X-ray, and the doctor can often remove stones or place stents during the same test.
Is bile duct obstruction serious?
It can be. Untreated blockage can lead to cholangitis, a bile duct infection that can turn into sepsis, plus lasting liver disease such as biliary cirrhosis. Treated promptly, most blockages can be relieved with endoscopy or surgery. Blockages caused by cancer often have a harder road.
