Management of Cholelithiasis

Asymptomatic Cholelithiasis: Observation is Standard

For asymptomatic gallstones, expectant management without surgery is recommended, as approximately 80% of patients remain asymptomatic throughout their lives and the condition follows a benign natural course. 1

  • Prophylactic cholecystectomy is not indicated for most asymptomatic patients, since only 30% will require surgery during their lifetime. 2

  • Specific exceptions requiring prophylactic cholecystectomy include:

    • Large gallstones >2.5 cm in diameter 2
    • Patients at risk for gallbladder cancer 3
    • Congenital hemolytic anemia or nonfunctioning gallbladder 2
    • Incidental discovery during bariatric surgery or colectomy 2

  • CCK-cholescintigraphy (GBEF measurement) has no role in predicting which asymptomatic patients will develop symptoms and should not be used for this purpose. 1

Symptomatic Cholelithiasis: Laparoscopic Cholecystectomy is Definitive

Laparoscopic cholecystectomy is the treatment of choice for symptomatic gallstones and should be performed during the same hospital admission or within 2-4 weeks to prevent recurrent biliary events. 4, 5

Clinical Presentation and Diagnosis

  • Classic biliary pain (right upper quadrant pain 30-60 minutes after meals) occurs in only a minority of patients; atypical symptoms including dyspepsia, bloating, nausea, and belching are more common. 1, 3

  • Ultrasonography is the gold standard diagnostic test with 90-95% sensitivity. 2

  • Do not delay referral based on atypical symptoms alone—ambiguous presentations are the norm, not the exception. 3

Surgical Timing

  • For acute cholecystitis, perform laparoscopic cholecystectomy within 10 days of symptom onset (ideally within 3 days for highest success rates). 3, 2

  • Elderly patients (>65 years) should receive early surgical referral, as laparoscopic cholecystectomy is safe and feasible when performed within this window. 3

  • Delaying cholecystectomy beyond 2-4 weeks significantly increases the risk of recurrent biliary complications. 5

Ursodeoxycholic Acid (UDCA): Limited Role in Specific Patients

UDCA therapy is reserved for highly selected symptomatic patients who are poor surgical candidates or who meet strict criteria for stone dissolution: radiolucent stones <10 mm in diameter with a visualized gallbladder on cholecystogram. 6, 7

Evidence for UDCA

  • Long-term UDCA (600 mg/day) reduces the risk of biliary pain in both symptomatic (62% vs. 92% at 10 years, relative risk 0.19) and asymptomatic patients (6% vs. 12% at 10 years, relative risk 0.19), independent of stone dissolution. 6

  • Complete stone dissolution occurs in approximately 50% of selected patients treated with 500-1000 mg/day for 6-38 months. 7

  • UDCA is safe with no adverse effects on liver function tests and no increase in biliary lithocholic acid. 7

Patient Selection Criteria

  • Three factors predict dissolution success (74% sensitivity, 95% specificity): radiolucent stones, small size (<10 mm), and visualized gallbladder on cholecystogram. 6

  • Large stones and increased stone number hinder dissolution. 7

  • UDCA is not a substitute for cholecystectomy in surgical candidates, as the gallbladder remains the source of future stones. 5

Choledocholithiasis: ERCP is First-Line Therapy

For common bile duct stones, endoscopic retrograde cholangiopancreatography (ERCP) with sphincterotomy and stone extraction is first-line therapy, achieving duct clearance in approximately 90% of cases. 4

Risk Stratification and Diagnostic Approach

  • High-risk patients (visible CBD stone on ultrasound, bilirubin >4 mg/dL, CBD diameter >6 mm with gallbladder in situ, or cholangitis) should proceed directly to ERCP. 4, 5

  • Moderate-risk patients (bilirubin 1.8-4 mg/dL or abnormal liver enzymes) require confirmatory imaging with MRCP (93% sensitivity) or EUS (95% sensitivity) before therapeutic intervention. 4, 5

  • Isolated liver enzyme elevation has only 15% positive predictive value for CBD stones and is insufficient for diagnosis alone. 4, 3

Timing of ERCP

  • Urgent ERCP within 24 hours is mandatory for cholangitis with severe sepsis, hemodynamic instability, or clinical deterioration despite antibiotics. 4, 5, 3

  • Early ERCP within 72 hours is indicated for persistent CBD stones, gallstone pancreatitis with ongoing obstruction, or cholangitis without severe sepsis. 4, 5

  • No randomized evidence demonstrates superiority of 24-hour versus 72-hour ERCP in clinically stable patients. 4

ERCP Techniques and Complications

  • For large or impacted stones (>10-15 mm), adjunctive lithotripsy (electrohydraulic or laser) succeeds in approximately 79% of attempts, though 30% require multiple sessions. 4

  • When complete stone removal is not possible, placement of an internal plastic stent provides adequate biliary drainage until definitive clearance. 4

  • Major complications (bleeding, perforation, pancreatitis) occur in 6-10% of all patients. 4

  • In elderly patients (≥70 years), complication rates rise to 19% with 7.9% mortality—extreme caution is required. 4, 5

Post-ERCP Management

  • Laparoscopic cholecystectomy should be performed during the same hospital admission after successful bile duct clearance to prevent recurrent biliary events. 4, 5

  • In poor surgical candidates, sphincterotomy and endoscopic duct clearance alone is acceptable but less effective than cholecystectomy for preventing recurrence. 4

Antibiotic Management for Cholangitis

When successful stone extraction provides adequate source control, postoperative antibiotics are unnecessary. 4

Non-Critically Ill, Immunocompetent Patients (Adequate Source Control)

  • Amoxicillin/clavulanate 2 g/0.2 g every 8 hours for 4 days total. 4

β-Lactam Allergy (Adequate Source Control)

  • Eravacycline 1 mg/kg every 12 hours or tigecycline (100 mg loading dose then 50 mg every 12 hours). 4

Critically Ill or Immunocompromised Patients (Adequate Source Control)

  • Piperacillin/tazobactam: loading dose 6 g/0.75 g then 4 g/0.5 g every 6 hours, or continuous infusion of 16 g/2 g; duration up to 7 days guided by clinical response. 4

Inadequate/Delayed Source Control or High ESBL Risk

  • Ertapenem 1 g every 24 hours or eravacycline 1 mg/kg every 12 hours. 4

Septic Shock

  • Meropenem 1 g every 6 hours (extended infusion), doripenem 500 mg every 8 hours (extended infusion), or imipenem/cilastatin 500 mg every 6 hours (extended infusion). 4

Persistent Infection Beyond 7 Days

  • Perform diagnostic re-evaluation for inadequate source control. 4

Percutaneous Cholecystostomy: Salvage for High-Risk Patients

Percutaneous transhepatic biliary drainage is the recommended alternative when ERCP fails or cannot be performed, particularly in critically ill patients with biliary sepsis. 4

  • In biliary sepsis where stones cannot be traversed, placement of internal/external catheters resolves sepsis in 100% of cases within 24 hours, even in patients with nondilated ducts. 4

  • Percutaneous stone removal techniques (balloon dilation of the papilla, forceful irrigation, balloon-tipped catheters) achieve success rates of 95-100% in experienced hands. 4

Critical Pitfalls to Avoid

  • Delay of biliary decompression in cholangitis with severe sepsis markedly increases mortality—urgent intervention within 24 hours is essential. 4

  • Do not rely solely on liver enzymes to rule out choledocholithiasis—additional imaging is mandatory. 4, 3

  • Coagulation status (INR/PT, platelet count) must be verified before sphincterotomy, and anticoagulation should be managed according to established endoscopy guidelines. 4

  • Atypical dyspeptic symptoms (indigestion, flatulence, heartburn, bloating) are less likely to resolve following cholecystectomy in patients with gallstones, but this does not change the indication for surgery in truly symptomatic patients. 1
