What is the recommended management for gallstones?

Management of Gallstones

Laparoscopic cholecystectomy is the first-line treatment for symptomatic gallstone disease, acute cholecystitis, and gallstone complications, providing definitive relief from gallstones and gallbladder-related complications. 1

Diagnostic Approach

• Initial Evaluation:
  • Abdominal ultrasound is the investigation of choice for diagnosing gallstone disease 1
  • Complete blood count and liver function tests should be performed as part of initial workup 1
  • HIDA scan has 80-90% sensitivity for diagnosing acute cholecystitis when gallbladder filling is absent within 60 minutes 1
  • MRCP is recommended for evaluating bile duct stones with high accuracy 1

Management Algorithm

1. Asymptomatic Gallstones

• Recommended approach: Watchful waiting
  • Annual risk of developing symptoms is only 2-6% per year 2
  • Prophylactic cholecystectomy generally not recommended 1
  • Exception: Consider cholecystectomy in high-risk subgroups:
    • Calcified gallbladders
    • Large stones (>3 cm)
    • Populations with high gallbladder cancer risk 1

2. Symptomatic Gallstones

• First-line treatment: Laparoscopic cholecystectomy 1
  • Benefits: Immediate and permanent stone removal
  • Timing: For uncomplicated cases, elective surgery
  • For gallstone pancreatitis: Cholecystectomy within 2 weeks of presentation, preferably during same admission 1
  • Post-surgical care: Discharge within 1-2 days, follow-up at 7-10 days 1

3. Acute Cholecystitis

• Management:
  • Early laparoscopic cholecystectomy (within 24 hours of admission) 3
  • One-shot antibiotic prophylaxis for early intervention 1
  • Antibiotic therapy should not exceed 7 days unless ongoing signs of infection 1
  • Recommended antibiotic regimens:
    • Non-critically ill: Amoxicillin/Clavulanate or Eravacycline/Tigecycline
    • Critically ill: Piperacillin/tazobactam or Eravacycline 1

4. Medical Therapy (Alternative to Surgery)

• Indications: Patients unfit for or refusing surgery 4
• Requirements:
  • Cholesterol-rich (radiolucent) stones
  • Patent cystic duct (confirmed by gallbladder opacification on oral cholecystography) 4
• Medication: Ursodiol (ursodeoxycholic acid)
  • Dosage: 8-10 mg/kg/day in 2-3 divided doses 2
  • Monitoring: Ultrasound at 6-month intervals for the first year 2
  • Limitations:
    • Suitable for only about 20% of cholecystectomy candidates
    • Long treatment duration (up to 2 years)
    • High recurrence rate (up to 50% within 5 years) 1, 2
    • Most effective for small stones (<6 mm) 4

Special Considerations

Surgical Risk Assessment

• Age >65 years alone is not a contraindication to cholecystectomy 1
• Controlled comorbidities (CKD, DM, HTN) should be evaluated but don't automatically preclude surgery 1
• Frailty assessment is more important than chronological age in determining surgical risk 1

Gallbladder Polyps

• Cholecystectomy recommended for:
  • Polyps >10 mm
  • Patients >50 years with polyps
  • Polyps with rapid growth
  • Sessile polyps 3

Common Pitfalls to Avoid

1. Misdiagnosing biliary colic: Characteristic pain is steady, moderate to severe in epigastrium or right upper quadrant, lasting 1-5 hours 5

2. Delaying surgery for acute cholecystitis: Delayed cholecystectomy is associated with longer hospital stay and convalescence due to recurrent episodes 6

3. Overtreatment of asymptomatic gallstones: The vast majority of asymptomatic patients should be managed by observation alone 7

4. Inadequate patient selection for medical therapy: Partial stone dissolution within 6 months indicates >70% chance of eventual complete dissolution; if not seen by 12 months, success likelihood is greatly reduced 2

5. Failing to convert to open surgery when needed: Conversion to open surgery is recommended with severe local inflammation, adhesions, bleeding from Calot's triangle, or suspected bile duct injury 1
