What are the primary treatment options for cholelithiasis?

Management of Cholelithiasis

Laparoscopic cholecystectomy is the primary treatment for symptomatic cholelithiasis, while asymptomatic gallstones should be managed expectantly. 1

Diagnostic Approach

• Clinical presentation: Right upper quadrant pain, fever, Murphy's sign
• Imaging:
  • Ultrasound: First-line investigation showing gallstones, pericholecystic fluid, distended gallbladder, edematous wall
  • CT with IV contrast: Alternative when ultrasound is inconclusive
  • MRCP: When common bile duct stones are suspected

Treatment Algorithm

Asymptomatic Cholelithiasis

• Expectant management is recommended due to:

  • Benign natural history
  • Low risk of complications
  • Up to 80% of patients remain asymptomatic throughout life 1

• Exceptions (consider prophylactic cholecystectomy):

  • Patients with calcified gallbladders
  • Large stones (>3 cm)
  • High-risk populations for gallbladder cancer 2

Symptomatic Cholelithiasis

1. First-line treatment: Laparoscopic cholecystectomy

   • Early intervention (within 7-10 days of symptom onset) is preferred 1
   • Benefits: Shorter recovery time, reduced hospitalization, lower risk of recurrent biliary symptoms
   • One-shot antibiotic prophylaxis for uncomplicated cases 2, 3

2. Antibiotic therapy:

   • Uncomplicated cases: Single-dose prophylaxis only
   • Complicated cases: 4-7 days based on clinical condition and inflammation indices 2, 3
   • For critically ill or immunocompromised patients with adequate source control: Piperacillin/tazobactam or alternatives for those with beta-lactam allergies 2

3. Alternative approaches for high-risk patients:

   • Percutaneous cholecystostomy: Bridge to definitive surgery in high-risk patients, though inferior to cholecystectomy for critically ill patients 2, 1
   • Laparoscopic cholecystostomy: Followed by interval laparoscopic cholecystectomy 4
   • Laparoscopic subtotal cholecystectomy: When anatomy is difficult 4

4. Non-surgical options (for selected patients unfit for surgery):

   • Oral bile acids (ursodeoxycholic acid 10 mg/kg/day or chenodeoxycholic acid 15 mg/kg/day):
     • Only effective for small (<6 mm), radiolucent, cholesterol-rich stones
     • Patent cystic duct required (confirmed by oral cholecystography)
     • Up to 75% dissolution rate annually with careful selection 5
   • Extracorporeal shock wave lithotripsy: For single stones <30 mm or multiple stones (n<3) 5
   • Contact dissolution with methyl-tert-butyl-ether: For stones of any size but still considered investigational 2, 5

Special Considerations

1. Mortality risk factors for cholecystectomy:

   • Age (increases with each decade)
   • Male gender (twice the risk of females)
   • Common duct exploration (quadruples risk)
   • Severe systemic disease (increases risk tenfold) 6

2. Recurrence after non-surgical treatment:

   • Approximately 50% recurrence rate after dissolution therapy
   • Cannot be reliably prevented with low-dose bile acids or dietary changes 5

3. Complications if left untreated:

   • Acute cholangitis
   • Biliary pancreatitis
   • Secondary biliary cirrhosis
   • Sepsis and multi-organ failure 1

Pitfalls and Caveats

• Bile duct injury is a serious potential complication of laparoscopic cholecystectomy, requiring surgeon experience and careful technique 2, 1
• Non-surgical treatments have high recurrence rates and limited applicability
• Patients with ongoing signs of infection beyond 7 days of antibiotic treatment warrant further diagnostic investigation 2
• Approximately 30% of patients with a single pain episode may not experience recurrence, allowing for observation in selected cases 2
