What Is Choledocholithiasis?

Choledocholithiasis occurs when a gallstone blocks the common bile duct. The common bile duct carries bile from the liver and gallbladder into the small intestine. When a stone obstructs this passage, bile cannot flow normally.

The blockage can cause abdominal pain, jaundice, abnormal liver function tests, and other symptoms. In some patients, stones may cause symptoms suddenly, while others may have no obvious symptoms initially.

Causes and Risk Factors

The most common cause of choledocholithiasis is the movement of gallstones from the gallbladder into the common bile duct.

Risk factors may include:

• Gallstones or a history of gallbladder stones
• Increasing age
• Obesity or being overweight
• Rapid weight loss
• Certain metabolic conditions
• Previous biliary disease or procedures
• Conditions that affect normal bile flow

Symptoms of Common Bile Duct Stones

Symptoms can vary depending on the size and location of the stone and the degree of bile duct obstruction.

Common symptoms include:

• Severe or recurring upper abdominal pain
• Pain in the right upper abdomen
• Pain radiating to the back or shoulder
• Nausea and vomiting
• Yellowing of the eyes or skin (jaundice)
• Dark-colored urine
• Pale or clay-colored stools
• Fever and chills, particularly when infection develops
• Indigestion or discomfort after meals

Severe abdominal pain, fever, or jaundice should not be ignored, as these symptoms may indicate bile duct obstruction or infection requiring urgent medical assessment.

How Is Choledocholithiasis Diagnosed?

A gastroenterologist may recommend a combination of clinical evaluation, blood tests, and imaging investigations.

Blood Tests

Liver function tests may show abnormalities when the bile duct is blocked. Blood tests can also help identify signs of infection or inflammation.

Ultrasound

Abdominal ultrasound is commonly used to look for gallstones and signs of biliary obstruction.

MRCP

Magnetic Resonance Cholangiopancreatography (MRCP) is a non-invasive imaging test that provides detailed images of the bile ducts and can help identify stones and obstruction.

EUS

Endoscopic Ultrasound (EUS) can provide highly detailed images of the bile ducts, gallbladder, pancreas, and surrounding structures. It may be useful when other imaging tests do not provide a definite diagnosis.

Treatment of Choledocholithiasis

Treatment depends on the patient’s symptoms, stone location, severity of obstruction, and presence of complications.

ERCP for Bile Duct Stone Removal

ERCP (Endoscopic Retrograde Cholangiopancreatography) is an important therapeutic procedure for selected patients with common bile duct stones.

During ERCP, an endoscope is passed through the mouth into the digestive tract. The bile duct is accessed and specialized instruments can be used to remove the obstructing stone and restore bile flow.

ERCP is primarily a therapeutic procedure rather than simply a diagnostic test and should be performed by an appropriately trained specialist when indicated.

Gallbladder Treatment

If gallstones are present in the gallbladder, removal of the gallbladder (cholecystectomy) may be recommended in appropriate patients after management of the common bile duct stone to reduce the risk of recurrent stones.

Possible Complications

Untreated or complicated choledocholithiasis may result in:

• Obstructive jaundice
• Acute cholangitis
• Acute pancreatitis
• Liver-related complications
• Recurrent biliary pain
• Severe infection in complicated cases

Prompt medical evaluation is especially important when a patient develops fever, jaundice, severe abdominal pain, vomiting, or chills.

When Should You Consult a Gastroenterologist?

You should seek medical evaluation if you experience persistent or severe abdominal pain, jaundice, unexplained vomiting, fever with abdominal pain, or other symptoms suggestive of a biliary disorder.

Early assessment can help determine whether gallstones or bile duct stones are present and whether further testing or treatment is required.
