Management of Cholelithiasis
For asymptomatic cholelithiasis, expectant management (observation) is recommended, as 80% of patients remain asymptomatic throughout their lives and the progression to symptomatic disease is low (10-25%), with surgery reserved only for those who develop symptoms or have high-risk conditions. 1
Asymptomatic Cholelithiasis
Observation is the standard approach for patients without symptoms, given the benign natural course and low rate of progression to complications. 1
- The majority of patients rarely develop gallstone-related complications without first experiencing at least one episode of biliary pain. 2
- Routine cholecystectomy for all asymptomatic patients is too aggressive and not indicated. 2
Exceptions requiring cholecystectomy in asymptomatic patients:
- Patients at increased risk for gallbladder cancer 1
- Patients undergoing abdominal surgery for unrelated conditions (concomitant cholecystectomy is reasonable in good-risk patients) 1, 2
Symptomatic Cholelithiasis
Laparoscopic cholecystectomy is the gold standard treatment for symptomatic gallstones, offering immediate and permanent stone removal with mortality rates as low as 0.054% in low-risk young women. 3, 4, 5
Classic biliary pain presentation:
- Right upper quadrant pain that is episodic and severe 1
- This is the primary indication for cholecystectomy 1
Critical pitfall - Atypical symptoms:
- Dyspeptic symptoms (indigestion, flatulence, heartburn, bloating, belching, nausea) are less likely to resolve following cholecystectomy and should not be primary indications for surgery. 1, 3
- There is no evidence that additional testing (such as CCK-cholescintigraphy) adds to clinical judgment in predicting surgical outcomes for patients with atypical symptoms. 1
Complicated Cholelithiasis
Acute Calculous Cholecystitis:
- Early laparoscopic cholecystectomy (within 7-10 days of symptom onset) is superior to delayed surgery, resulting in shorter recovery time and hospitalization. 1, 3
- Diagnosis is made by ultrasound showing: gallbladder wall thickening (>5mm), pericholecystic fluid, distended gallbladder, and positive sonographic Murphy's sign 1
- Initiate broad-spectrum antibiotics (third-generation cephalosporins, fluoroquinolones, or carbapenems) while preparing for surgery 1
Choledocholithiasis (Common Bile Duct Stones):
- ERCP with sphincterotomy and stone extraction achieves 90% success in clearing the common bile duct and is the primary therapeutic approach. 6
- For suspected CBD stones, obtain MRCP (93% sensitivity) or EUS (95% sensitivity) in moderate-risk patients before intervention 6
- If ERCP fails, percutaneous transhepatic approach achieves 95-100% success rates 6
- Laparoscopic CBD exploration is reserved for refractory cases, with 95% success rates and 5-18% complication rates 1, 6
Acute Cholangitis:
- Immediate biliary decompression must be performed urgently (within 24 hours) in patients with severe sepsis or deteriorating despite antibiotics - this is lifesaving. 6
Medical Dissolution Therapy
Medical therapy with ursodeoxycholic acid is NOT a primary treatment option but may be considered only in patients who refuse surgery or are not surgical candidates. 4, 7
Ursodeoxycholic acid criteria (when surgery is refused/contraindicated):
- Dose: 8-10 mg/kg/day 4, 7
- Only effective for small (<5mm), radiolucent (cholesterol-rich) stones 3, 4
- Requires patent cystic duct (confirmed by gallbladder visualization on imaging) 4, 7
- Complete dissolution occurs in only 30% of unselected patients after up to 2 years of treatment 4
- Stone recurrence occurs in up to 50% of patients within 5 years after dissolution 4, 7
- Calcified stones or stones >20mm rarely dissolve 4
Surgical Risk Stratification
Mortality rates vary significantly by patient characteristics 4:
- Low-risk women <49 years: 0.54 per 1000 operations 4
- Low-risk men <49 years: 1.04 per 1000 operations 4
- Rates increase 10-fold with severe systemic disease 4
- Common duct exploration quadruples mortality rates in all categories 4
Key Clinical Pitfalls to Avoid
- Do not perform cholecystectomy for vague dyspeptic symptoms alone - these symptoms are unlikely to improve after surgery 1, 3
- Do not delay biliary decompression in acute cholangitis with sepsis - intervention must occur within 24 hours 6
- Do not use CCK-cholescintigraphy to predict which asymptomatic patients will become symptomatic - there is no evidence this testing is useful 1
- Do not rely on medical dissolution as primary therapy - it has low success rates, high recurrence rates, and is only appropriate when surgery is contraindicated 4, 7
