Understanding benign biliary conditions

What are benign biliary diseases?

These are non-cancerous conditions affecting the bile ducts or gallbladder. The common ones are:

• Cholelithiasis (gallstones): stones formed in the gallbladder or bile ducts.
• Cholangitis: inflammation of the bile ducts, usually from infection or obstruction.
• Choledocholithiasis: gallstones lodged in the common bile duct.
• Biliary strictures: narrowing of the bile ducts, often after injury or inflammation.
• Biliary dyskinesia: dysfunctional bile duct or gallbladder motility.
• Primary biliary cholangitis (PBC): a chronic autoimmune disease causing bile duct damage.

What causes them?

• Gallstones: bile composition imbalance, obesity, or rapid weight loss.
• Cholangitis: usually bacterial infection following bile duct obstruction.
• Strictures: may develop after surgery, injury or chronic inflammation.
• Biliary dyskinesia: often idiopathic, though stress and hormonal change may contribute.
• Primary biliary cholangitis: an autoimmune reaction damaging the small bile ducts.

What are the symptoms?

• Right upper abdominal pain, especially after fatty food.
• Jaundice — yellowing of the skin and eyes.
• Dark urine and pale stools.
• Nausea and vomiting.
• Fever and chills, suggesting infection.
• Persistent fatigue, common in PBC.

How are they diagnosed?

• Medical history and physical examination.
• Blood tests: liver function tests, bilirubin, and markers such as ALP and GGT.
• Ultrasound: first-line for gallstones and bile duct obstruction.
• MRCP: non-invasive magnetic resonance imaging of the bile ducts.
• ERCP: used for both diagnosis and treatment.
• Biopsy: may be required for conditions such as primary biliary cholangitis.

What are the treatment options?

Treatment follows the specific condition rather than the symptom.

• Gallstones: asymptomatic stones may need no treatment; cholecystectomy is recommended for symptomatic stones.
• Cholangitis: antibiotics plus bile duct drainage via ERCP.
• Biliary strictures: endoscopic stenting or balloon dilation to open the narrowed duct.
• Biliary dyskinesia: cholecystectomy if symptoms are severe.
• Primary biliary cholangitis: medication such as ursodeoxycholic acid (UDCA) to slow progression.

What complications can arise if untreated?

• Biliary colic: severe pain from gallstone obstruction.
• Acute cholangitis: a life-threatening infection of the bile ducts.
• Pancreatitis: inflammation of the pancreas from bile duct obstruction.
• Biliary cirrhosis: chronic liver damage from prolonged obstruction or disease.

When should you consult a specialist?

• Persistent abdominal pain or discomfort.
• Symptoms of jaundice or infection — fever, chills.
• Recurrent episodes of biliary colic.
• Diagnosed gallstones with complications such as pancreatitis or cholangitis.

Are they preventable?

• Maintain a healthy weight — obesity increases gallstone risk.
• Adopt a balanced diet, high in fibre and low in unhealthy fats.
• Stay hydrated to support bile production and flow.
• Exercise regularly.
• Treat infections or gallstone symptoms early, before complications develop.
