Introduction
Choledocholithiasis, the presence of stones in the common bile duct (CBD), is a serious condition that can lead to complications like cholangitis, pancreatitis, and obstructive jaundice. Effective choledocholithiasis management involves prompt diagnosis, medical stabilization, and definitive stone removal. This guide outlines a structured approach to treatment, ensuring optimal patient outcomes.
Symptoms and Clinical Presentation
1. Key Symptoms of Choledocholithiasis
Patients with choledocholithiasis typically present with:
- Severe right upper quadrant (RUQ) pain (lasting >6 hours, often postprandial)
- Referred pain to the epigastrium, right shoulder, or back
- Nausea, vomiting, and anorexia
- Signs of cholestasis: Jaundice, pale stools, dark urine, and pruritus
- Complications such as acute pancreatitis, cholecystitis, or cholangitis
Treatment is necessary even in asymptomatic cases to prevent severe complications.
Initial Stabilization and Diagnostic Workup
2. Immediate Medical Management
- ABCDE approach (Airway, Breathing, Circulation, Disability, Exposure)
- Two large-bore IV cannulas for fluid resuscitation
- Frequent vitals monitoring (BP, PR, RR, Temperature, SpO2)
- NPO (Nil Per Os) to rest the biliary system
- NG tube and Foley catheter if needed
3. Essential Laboratory Tests
- CBC (for infection signs)
- Liver Function Tests (LFTs) (elevated bilirubin, ALP, GGT)
- Amylase/Lipase (to rule out pancreatitis)
- Coagulation profile (PT/INR/APTT)
- Electrolytes & Renal Function Tests (Urea/Creatinine)
4. Imaging for Confirmation
- Ultrasound (First-line) – Detects gallstones and CBD dilation (>8mm suggests obstruction)
- CT Abdomen with Contrast – Useful for complications like abscesses
- MRCP (Gold Standard) – 95% sensitivity & 98% specificity for CBD stones
- ERCP (Diagnostic & Therapeutic) – Best for both diagnosis and stone removal
Medical Treatment of Choledocholithiasis
5. IV Fluid & Electrolyte Management in Choledocholithiasis
- Ringer’s Lactate or 0.9% Normal Saline to maintain hydration
- Correct electrolyte imbalances (especially potassium and sodium)
6. Empiric IV Antibiotics for Choledocholithiasis
For suspected infection (cholangitis/cholecystitis):
- First-line: Metronidazole 500mg IV TDS + Ceftriaxone 1g IV BD
- Alternatives:
- Ciprofloxacin 400mg IV BD
- Ceftazidime 1g IV BD
- Severe infections: Meropenem 1g IV TDS or Piperacillin-Tazobactam 4.5g IV TDS
7. Pain and Symptom Control in Choledocholithiasis
- Mild pain: Ketorolac 30mg IV
- Severe pain: Buprenorphine 0.3mg IV or Nalbuphine 10mg IV (with Dimenhydrinate for nausea)
- Fever/analgesia: IV Paracetamol 1g TDS
- Antiemetics: Ondansetron 4mg IV or Metoclopramide 10mg IV
8. Adjunctive Therapies
- Proton Pump Inhibitors (PPIs): Omeprazole 40mg IV OD (prevents stress ulcers)
Definitive Treatment: Stone Removal
9. ERCP (Endoscopic Retrograde Cholangiopancreatography)
- First-line treatment for CBD stones
- Allows stone extraction, stent placement, or sphincterotomy
- Success rate: >90%
10. Surgical Options for Choledocholithiasis
- Laparoscopic CBD Exploration (LCBDE) – Alternative if ERCP fails
- Mechanical/Laser Lithotripsy – For large or impacted stones
- Elective Cholecystectomy – Prevents recurrence (performed after ERCP)
Post-Treatment Care & Prevention
- Monitor for complications (bleeding, infection, pancreatitis)
- Gradual diet reintroduction (start with liquids, then solids)
- Follow-up imaging if symptoms persist
Conclusion
Effective choledocholithiasis management requires a combination of medical stabilization, accurate imaging, antibiotics, and timely stone removal (ERCP/surgery). Early intervention prevents life-threatening complications like cholangitis and pancreatitis.
