Treatment of Cholelithiasis
Laparoscopic cholecystectomy is the first-line treatment for all symptomatic gallstones, ideally performed within 7-10 days of symptom onset, while asymptomatic gallstones should be managed expectantly. 1
Asymptomatic Cholelithiasis
Expectant management (watchful waiting) is recommended for asymptomatic gallstones because approximately 80% of patients remain asymptomatic throughout their lives with minimal progression to complications. 1 The risk of developing moderate-to-severe symptoms or complications is only 2-6% per year, accumulating to 7-27% over 5 years. 2
Exceptions requiring prophylactic cholecystectomy:
- Calcified ("porcelain") gallbladder 3
- New World Indians (e.g., Pima Indians) due to high gallbladder cancer risk 3
- Stones larger than 3 cm 3
Symptomatic Cholelithiasis
Primary Surgical Management
Laparoscopic cholecystectomy is the definitive treatment for all symptomatic gallstones regardless of stone size. 1 This approach provides immediate and permanent stone removal with high success rates and low morbidity. 1
Optimal Timing
Early laparoscopic cholecystectomy should be performed within 7 days of hospital admission and within 10 days of symptom onset for acute cholecystitis. 3, 4 This timing results in:
- Shorter total hospital stay (approximately 4 days less than delayed surgery) 3
- Earlier return to work (approximately 9 days sooner) 3
- Lower conversion rates 4
If early surgery cannot be performed within this window, delayed laparoscopic cholecystectomy should be scheduled after 6 weeks from initial presentation. 4
Antibiotic Protocols
For uncomplicated cholecystitis: Single-dose antibiotic prophylaxis with no postoperative antibiotics if source control is adequate. 3, 4
For complicated cholecystitis in immunocompetent, non-critically ill patients: 4 days of antibiotic therapy if source control is adequate. 3, 4
For immunocompromised or critically ill patients: Up to 7 days of antibiotic therapy based on clinical response and inflammatory markers. 3, 4
Surgical Risk Stratification
Mortality rates vary significantly by patient characteristics 2:
- Low-risk women under 49 years: 0.054% mortality
- Men have approximately twice the surgical mortality of women in all age categories 2
- Mortality increases substantially with age and presence of severe systemic disease 2
- Common bile duct exploration quadruples mortality rates 2
Special Populations
Pregnancy
Laparoscopic cholecystectomy is safe during any trimester but ideally performed in the second trimester. 1, 3 Conservative management has a 60% recurrence rate of biliary symptoms. 3 For pregnant patients with acute biliary pancreatitis, same-admission cholecystectomy reduces early readmission by 85%. 3
Elderly Patients
Age alone is not a contraindication for laparoscopic cholecystectomy. 1, 3 Laparoscopic cholecystectomy in elderly patients results in lower 2-year mortality compared to nonoperative management. 3
Cirrhotic Patients
Laparoscopic cholecystectomy is first choice for Child-Pugh A and B cirrhosis. 3 Child-Pugh C or decompensated cirrhosis patients should avoid cholecystectomy unless clearly indicated. 3
Non-Surgical Options
Oral Bile Acid Therapy (Ursodeoxycholic Acid)
Reserved for highly select patients who refuse surgery or are poor surgical candidates with strict criteria 1:
- Small stones (< 5-6 mm diameter) 1, 3
- Radiolucent (cholesterol-rich) stones 1, 3
- Patent cystic duct 3
- Functioning gallbladder 3
This option does not reduce gallbladder cancer risk and has high recurrence rates. 3
Percutaneous Cholecystostomy
May be considered for acute cholecystitis in patients with multiple comorbidities who are truly unfit for surgery and fail to improve with antibiotics. 3, 4 However, cholecystostomy is inferior to cholecystectomy with significantly more major complications (53% vs 5%). 3, 4 It can serve as a bridge to cholecystectomy after patient stabilization. 3
Diagnostic Evaluation
Ultrasound is the investigation of choice for suspected acute cholecystitis showing pericholecystic fluid, distended gallbladder, edematous wall, gallstones, and positive sonographic Murphy's sign. 1, 4
CT with IV contrast is an alternative diagnostic tool. 1, 4
MRCP (magnetic resonance cholangiopancreatography) is recommended for suspected common bile duct stones. 3, 4
Critical Pitfalls to Avoid
Atypical symptoms (indigestion, flatulence, heartburn, bloating, belching, nausea) are less likely to resolve following cholecystectomy compared to classic biliary pain. 1, 3 These patients should be counseled that surgery may not relieve their symptoms. 1
Ensure surgeon experience and qualifications as bile duct injury is a potential complication of laparoscopic cholecystectomy. 1, 4
Do not delay cholecystectomy beyond 4 weeks in mild gallstone pancreatitis as this increases risk of recurrent attacks. 3, 4
Conversion to open surgery is not a failure but a valid option when laparoscopic expertise has been maximized or anatomy is unclear. 3, 4 Risk factors for conversion include age >65 years, male gender, acute cholecystitis, thickened gallbladder wall, diabetes, and previous upper abdominal surgery. 4
