Choledocholithiasis awareness

Overview

Choledocholithiasis (say ko-lee-doe-ko-lith-eye-uh-sis) is a condition where a gallstone—a small, hard stone made of cholesterol or other substances—gets stuck in the common bile duct, the main tube that carries bile from the liver and gallbladder to the small intestine. This blockage can cause bile to back up, leading to pain, jaundice (yellowing of the skin and eyes), and infection.

Yes, choledocholithiasis is a relatively common problem, especially in people who have gallstones. It occurs in about 10–15% of people with gallbladder stones.

It mostly affects adults over the age of 40, and is more common in women. People who have had gallstones before, are overweight, eat a high-fat diet, or have certain medical conditions (like diabetes or sickle cell disease) are at higher risk.

Symptoms

Common symptoms

• Severe pain in the upper right side of the belly that may come and go or last for hours
• Nausea and vomiting
• Jaundice (yellowing of the skin or the whites of the eyes)
• Dark urine and pale or clay-colored stools
• Fever and chills (if an infection develops)

Symptoms in children

• Children may have similar symptoms, but they may not be able to describe the pain clearly. Look for fussiness, poor feeding, or a yellow tint to the skin.

Symptoms in older adults

• Older adults may not have typical pain. Instead, they might feel confused, weak, or just generally unwell. They can also develop jaundice or fever without obvious pain.

Causes

Main causes

• Gallstones that form in the gallbladder and travel into the common bile duct
• Less commonly, stones that form directly in the bile duct itself

Risk factors

• Having a history of gallstones
• Obesity or being overweight
• Rapid weight loss (such as after bariatric surgery)
• A diet high in fat and low in fiber
• Diabetes or insulin resistance
• Cirrhosis of the liver
• Certain blood disorders like sickle cell disease or hereditary spherocytosis

When to see a doctor

See a doctor urgently if:

• If you have fever, chills, and belly pain—especially with confusion or jaundice—go to the emergency room right away.
• If you have severe, constant belly pain or vomiting that prevents you from drinking fluids.

Book a routine appointment if:

• If you have mild, intermittent pain after meals (especially fatty meals) that has happened more than once.
• If you notice your skin or eyes turning yellow, even if you feel okay otherwise.

Diagnosis

Doctors usually suspect choledocholithiasis based on your symptoms and blood tests that show signs of bile duct blockage or infection. They then use imaging tests to confirm the diagnosis.

Tests that may be done

• Blood tests (liver function tests and bilirubin levels)
• Abdominal ultrasound – a first-line test to look for gallstones and dilated bile ducts
• MRCP (magnetic resonance cholangiopancreatography) – a special MRI scan that shows the bile ducts clearly
• ERCP (endoscopic retrograde cholangiopancreatography) – a procedure that can both diagnose and treat the blockage by removing the stone

What to expect at your appointment

You’ll likely be referred to a gastroenterologist (a doctor who specialises in the digestive system). They will decide which tests are needed. ERCP is usually done with sedation, and you may need to stay in hospital for a day or two if an infection is present.

Treatment

The main goal of treatment is to remove the stone from the bile duct and to treat any infection. Most people will need a procedure called ERCP, during which the doctor uses a small camera on a flexible tube to find and remove the stone.

Self-care at home

• Take pain relievers as recommended by your doctor (paracetamol or ibuprofen may help, but check with a pharmacist first)
• Drink plenty of water to stay hydrated
• Rest until the pain or fever improves

Medical treatments

Doctors may prescribe antibiotics if there is a bile duct infection (cholangitis). Pain medications can be given to manage abdominal pain. These are usually given through a vein in hospital if the pain is severe.

When is surgery considered?

After the stone in the bile duct is removed, your doctor may recommend surgery to remove the gallbladder (cholecystectomy) to prevent future stones from forming and migrating into the duct. This surgery is often done laparoscopically (keyhole surgery) and is not urgent—usually scheduled weeks after the ERCP.

Living with this condition

After successful treatment, most people recover within a few days. You may feel tired or have mild discomfort for a short time. Follow your doctor’s advice about rest and diet.

Lifestyle tips

• Maintain a healthy weight with a balanced diet and regular exercise
• Avoid crash diets or rapid weight loss, which can promote stone formation
• Limit high-fat and fried foods

Diet and exercise

Eat a diet rich in fruits, vegetables, whole grains, and lean proteins. Smaller, more frequent meals can be easier on your digestion. Regular moderate exercise (like brisk walking for 30 minutes a day) helps maintain a healthy weight and reduces the risk of gallstones.

Mental health and emotional wellbeing

Dealing with pain, jaundice, or a hospital stay can be stressful. Some people feel anxious about future episodes. It’s normal to have these feelings—talk to your doctor or a counsellor if they affect your daily life.

Prevention

You can lower your risk of developing choledocholithiasis by managing the same risk factors that cause gallbladder stones. This includes maintaining a healthy weight, eating a low-fat, high-fiber diet, avoiding rapid weight loss, and staying physically active.

Screening programmes

There is no routine screening for choledocholithiasis in people without symptoms. If you have gallstones or risk factors, your doctor may monitor you with occasional ultrasounds.

Complications

If left untreated

• Cholangitis – a serious infection of the bile duct that can spread to the bloodstream
• Pancreatitis – inflammation of the pancreas, which can be painful and dangerous
• Liver damage or cirrhosis from long-standing blockage
• Sepsis – a life-threatening body-wide infection

Long-term outlook

With prompt diagnosis and treatment, the outlook for choledocholithiasis is excellent. Most people recover fully and have no long-term problems. Removing the gallbladder afterwards greatly reduces the chance of it happening again.
