Choledocholithiasis

Choledocholithiasis is the presence of one or more gallstones within the common bile duct (CBD). These stones can obstruct bile flow, leading to cholestasis, biliary colic, obstructive jaundice, ascending cholangitis, or gallstone pancreatitis.

• Secondary Stones (Most Common): Gallstones formed in the gallbladder that migrate through the cystic duct into the CBD.

Obstruction of the CBD by a stone increases intraductal pressure and impairs bile secretion. Stagnant bile promotes bacterial colonization (ascending infection), leading to acute cholangitis. Prolonged obstruction leads to systemic conjugated hyperbilirubinemia. If the stone obstructs the ampulla of Vater, it blocks the pancreatic duct, triggering premature activation of pancreatic enzymes and acute pancreatitis.

Choledocholithiasis occurs in approximately 10–20% of patients with symptomatic cholelithiasis. Prevalence increases with age, showing a slight female predominance mirroring cholelithiasis patterns.

• History of cholelithiasis (gallstones)
• Advanced age (>60 years)
• Female sex
• Obesity or rapid weight loss
• Pregnancy
• Chronic hemolytic anemias (pigment stones)

• Vitals: Fever, tachycardia, or hypotension (in cholangitis/sepsis).
• Inspection: Scleral icterus and generalized jaundice.
• Palpation: RUQ tenderness; guarding may be present. Murphy's sign is classically negative unless concurrent acute cholecystitis is present.

• A. Clinical Assessment: Clinical presentation of biliary pain and jaundice.
• B. Laboratory Testing: Demonstrates an obstructive pattern.
• C. Imaging Studies: Transabdominal ultrasound, MRCP, or EUS.
• D. Functional Tests: HIDA scan (rarely indicated for CBD stones).
• E. Biopsy Findings: Not indicated.
• F. Genetic Testing: Generally not indicated unless investigating rare familial cholestatic syndromes.
• G. Differential Diagnosis: Differentiating biliary obstruction from hepatocellular injury, strictures, or malignancies.

Liver Function Tests (LFTs)

• Type: Blood Test


• Purpose: To assess for cholestasis and hepatocyte injury.


• Expected Findings: Elevated alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), and direct (conjugated) bilirubin. AST and ALT may show mild-to-moderate elevations.


• Interpretation: An obstructive jaundice pattern (disproportionately elevated ALP/GGT compared to AST/ALT). Serum Amylase and Lipase


• Type: Blood Test


• Purpose: To screen for secondary gallstone pancreatitis.


• Expected Findings: Elevated (>3x upper limit of normal).


• Interpretation: Indicates pancreatic duct obstruction and acute pancreatitis.

• Transabdominal Ultrasound (US): First-line screening. Shows CBD dilation (>6 mm) and occasionally direct visualization of the echogenic stone with posterior acoustic shadowing. High specificity but lower sensitivity for distal CBD stones.
• Magnetic Resonance Cholangiopancreatography (MRCP): Highly sensitive and specific non-invasive gold standard. Reveals filling defects within the hyperintense bile duct on T2-weighted images.
• Endoscopic Ultrasound (EUS): Highly sensitive for small stones (<5 mm) near the ampulla; non-invasive alternative to ERCP.
• Endoscopic Retrograde Cholangiopancreatography (ERCP): Both diagnostic and therapeutic. Identifies filling defects via fluoroscopy under direct endoscopic visualization.

• Acute Cholecystitis: Localized cystic duct obstruction; positive Murphy's sign, lack of significant hyperbilirubinemia or CBD dilation.
• Cholangiocarcinoma: Painless, progressive jaundice with strictures and constitutional symptoms (weight loss).
• Mirizzi Syndrome: Extrinsic compression of the CBD by a stone impacted in the gallbladder neck or cystic duct.

• Acute ascending cholangitis
• Gallstone pancreatitis
• Secondary biliary cirrhosis (due to chronic obstruction)
• Hepatic abscess

Excellent if diagnosed and treated early. ERCP stone extraction is successful in >90% of cases. Delay in treatment can lead to life-threatening complications like septic shock or severe necrotizing pancreatitis.

• Cholecystectomy following the first episode of symptomatic gallstones or documented choledocholithiasis.
• Ursodeoxycholic acid (for prevention of recurrent gallstones in select populations).
