What is the Best Treatment for Choledocholithiasis?

Choledocholithiasis Explained: Causes, Diagnosis & Top Treatments

Gallstones are a common health concern that often affects the gallbladder. In some cases, the stones can migrate into the Common Bile Duct (CBD), a condition known as choledocholithiasis. If not treated promptly, this condition can cause serious health problems, such as jaundice, infection, or pancreatitis.

Choledocholithiasis may be asymptomatic in the early stages or present with symptoms like abdominal pain, nausea, vomiting, dark urine, or pale stools. Diagnosis is usually confirmed by imaging, such as ultrasound, MRCP (Magnetic Resonance Cholangiopancreatography), or endoscopic ultrasound (EUS).

When confirmed, timely and effective treatment is essential. However, treatment varies depending on the size and number of stones, associated symptoms, presence of gallbladder stones, and the overall patient health. Keep reading to understand the optimal treatment and prevention methods for choledocholithiasis.

What is the first-line treatment for choledocholithiasis?

The first-line treatment for most cases of choledocholithiasis is endoscopic retrograde cholangiopancreatography (ERCP) with or without sphincterotomy. This minimally invasive endoscopy allows doctors to access and clear the bile duct stone through the digestive tract without any external incisions.

Listed below are the first-line treatment methods for choledocholithiasis:

1.  Endoscopic Removal (ERCP ± Sphincterotomy)

Endoscopic retrograde cholangiopancreatography (ERCP) with stone removal is the first-line treatment for symptomatic choledocholithiasis. A gastroenterologist inserts a flexible endoscope through the mouth into the duodenum, locates the bile duct opening, performs a sphincterotomy (cuts the sphincter of Oddi), and uses specialised tools to remove the stones.

• Success rates are around 85–90% for common stones.
• For larger or multiple stones (>12–15 mm), adjuvant treatments such as balloon dilation, electrohydraulic, or laser lithotripsy may be used.
• ERCP also allows stent placement for drainage when immediate stone clearance is not possible.
• Risks include pancreatitis (up to 5–10%), bleeding, and perforation.

2.  Surgical Removal During Cholecystectomy

A single-stage surgical approach may be optimal when stones coexist in the gallbladder and the bile duct.

• Laparoscopic common bile duct exploration(LCBDE) performed during laparoscopic cholecystectomy removes stones directly from the duct.
• Alternatively, the laparo-endoscopic rendezvous(LERV) combines laparoscopy with intraoperative ERCP for efficient stone clearance.
• Studies show that one-stage approaches are as effective as two-stage procedures (ERCP plus delayed cholecystectomy), often with shorter hospital stays and fewer procedures.

3.  Percutaneous & Radiologic Approaches

For patients who are poor surgical or endoscopic candidates, percutaneous techniques offer the following alternatives:

• Percutaneous transhepatic cholangiography(PTHC) allows bile duct access through a catheter inserted via the liver, enabling balloon dilation or stone extraction.
• Percutaneous drainage plus lithotripsycan fragment and clear large stones through external access.
• Biliary stentingcan be used as a long-term measure when definitive stone removal is impossible.

4.  Non-Surgical Lithotripsy and Dissolution

These options are rarely used today but may be suitable in select cases:

• Extracorporeal shock wave lithotripsy(ESWL) uses external sound waves to fragment stones before ERCP.
• Electrohydraulic or laser lithotripsy, used during endoscopy or percutaneous procedures, targets stones directly.
• Oral dissolution (ursodeoxycholic acid/UDCA)is slow and effective mainly for small cholesterol stones.

5.  Treatment Based on Disease Presentation

• Asymptomatic stonesare often monitored; many pass spontaneously without intervention but may require intervention due to risks of complications like cholangitis or pancreatitis.
• Symptomatic stones, especially those associated with cholangitisor biliary pancreatitis, require prompt removal. Early ERCP is recommended when inflammation occurs, though the timing is debated for uncomplicated cases.
• Cholecystectomy is typically performed either immediately or within 72 hours after duct clearance to prevent recurrence.

6.  Preventing Recurrence & Complications

• Cholecystectomy (surgical gallbladder removal) is advised once duct stones are cleared to prevent future episodes.
• Regular follow-up imaging and liver/biliary studies help monitor for retained or recurrent stones.
• Diet and lifestyle adjustments may reduce gallstone formation, but cholecystectomy is strongly recommended after choledocholithiasis to prevent recurrence.

How to Prevent Choledocholithiasis?

Preventing choledocholithiasis (common bile duct stones) involves maintaining a healthy lifestyle and addressing risk factors associated with gallstone formation:

1. Eat a Balanced, Low-Cholesterol Diet: Include high-fibre foods such as fruits, vegetables, and whole grains while limiting fatty and fried foods to reduce cholesterol saturation in bile.
2. Maintain a Healthy Weight: Obesity increases the risk of gallstones. If overweight, aim for gradual, sustainable weight loss, as rapid weight loss may actually trigger stone formation.
3. Stay Hydrated: Drinking enough water helps keep bile fluid and reduces the risk of stone crystallisation.
4. Exercise Regularly: Consistent physical activity improves metabolism and reduces gallstone risk by aiding fat digestion and bile flow.
5. Manage Underlying Conditions: Control diabetes, high triglycerides, and liver diseases that may contribute to abnormal bile composition or impaired drainage.

The best treatment for choledocholithiasis typically begins with ERCP and sphincterotomy with stone extraction, supported by adjunctive techniques, especially for larger stones.

In patients with concurrent gallbladder stones, a single-stage surgical approach (LCBDE or LERV) can be equally effective and efficient. Percutaneous techniques and stent drainage offer viable alternatives for those unable to undergo traditional methods.
