What is the recommended treatment for symptomatic gallbladder (cholelithiasis) stones?

Treatment for Symptomatic Gallbladder Stones

Laparoscopic cholecystectomy is the definitive treatment of choice for symptomatic gallstones (cholelithiasis). 1

Diagnostic Approach

• Initial evaluation:
  • Abdominal ultrasound is the investigation of choice for diagnosing gallstone disease (sensitivity 90-95%)
  • Complete blood count and liver function tests should be performed to assess for common bile duct stones
  • HIDA scan may be used for diagnosing acute cholecystitis (80-90% sensitivity)

Treatment Algorithm

1. Symptomatic Gallstones Without Complications

• First-line treatment: Laparoscopic cholecystectomy
  • Offers permanent stone removal
  • Most patients can be discharged within 1-2 days after surgery 1
  • Patients typically resume normal activities within 1 week

2. Symptomatic Gallstones With Common Bile Duct Stones

• Treatment options:
  • Laparoscopic cholecystectomy with laparoscopic bile duct exploration (LBDE) 1
  • ERCP with biliary sphincterotomy and stone extraction, followed by laparoscopic cholecystectomy 1

3. Acute Cholecystitis

• Initial management:
  • Broad-spectrum antibiotics should be started immediately upon diagnosis 1
  • Laparoscopic cholecystectomy should be performed within 2 weeks of presentation, preferably during the same admission 1
  • Surgery is more likely to be successful when performed within 3 days of symptom onset

4. Gallstone Pancreatitis

• Early laparoscopic cholecystectomy (within 2 weeks of presentation) should be offered to prevent recurrent episodes 1

5. High Surgical Risk Patients

• Alternative treatment options:
  • Ursodiol (oral dissolution therapy): 8-10 mg/kg/day in 2-3 divided doses 2
    • Ultrasound follow-up at 6-month intervals to monitor response
    • Partial dissolution within 6 months suggests >70% chance of eventual complete dissolution
    • Not effective for calcified stones
  • Endoscopic biliary sphincterotomy may be considered to reduce recurrent biliary events if cholecystectomy is contraindicated 1

Special Considerations

Elderly Patients

• Age >65 years alone is not a contraindication to cholecystectomy 1
• Frailty assessment is more important than chronological age in determining surgical risk 1
• Cholecystectomy can be safely performed up to 10 days from symptom onset in elderly patients 1

Asymptomatic Gallstones

• Prophylactic cholecystectomy is generally not recommended for most patients with asymptomatic gallstones 1
• May be considered in specific high-risk subgroups:
  • Patients with calcified gallbladders
  • Large stones (>3 cm)
  • Populations with high gallbladder cancer risk 1

Rapid Weight Loss Patients

• Prophylactic ursodiol (600 mg/day) can be used for gallstone prevention in patients undergoing rapid weight loss 2
  • Studies show reduction in gallstone formation from 23% (placebo) to 1-3% (with ursodiol 600 mg/day) 2

Follow-up Care

• Follow-up at 7-10 days post-surgery for wound evaluation 1
• For patients treated with ursodiol:
  • Ultrasound images should be obtained at 6-month intervals for the first year 2
  • If partial stone dissolution is not seen by 12 months, the likelihood of success is greatly reduced 2
  • Stone recurrence after dissolution occurs in 30-50% of patients within 2-5 years 2

Potential Complications

• Conversion to open surgery may be necessary in cases of:
  • Severe local inflammation
  • Adhesions
  • Bleeding from Calot's triangle
  • Suspected bile duct injury 1
• About 5% of cholecystectomized patients have residual symptoms or retained common duct stones 2

Laparoscopic cholecystectomy remains the gold standard treatment for symptomatic gallstones, providing immediate and permanent stone removal with significantly less postoperative pain, shorter hospitalization, and faster recovery compared to open cholecystectomy.
