What are the treatment options for cholelithiasis?

Treatment of Cholelithiasis

Early laparoscopic cholecystectomy is the recommended first-line treatment for symptomatic cholelithiasis, ideally performed within 7 days of hospital admission and within 10 days of symptom onset. 1

Diagnostic Evaluation

• Ultrasound is the investigation of choice for suspected acute cholecystitis due to its high accuracy for gallbladder stones, lack of invasiveness, and relatively low cost 1, 2
• Typical ultrasound findings include pericholecystic fluid, distended gallbladder, edematous gallbladder wall, and gallstones 1
• CT with IV contrast may be used as an alternative for diagnostic evaluation 1
• MRCP (magnetic resonance cholangiopancreatography) is recommended for patients with suspected common bile duct stones 1, 2

Treatment Algorithm Based on Symptom Status

Asymptomatic Gallstones

• Expectant management (watchful waiting) is recommended for patients with asymptomatic gallstones due to the low risk of developing complications (2-6% per year) 2, 3
• Exceptions where prophylactic cholecystectomy may be considered include:
  • Patients at high risk for gallbladder cancer (calcified gallbladders, New World Indians) 2
  • Patients with large stones (>3 cm) 2

Symptomatic Gallstones

• Laparoscopic cholecystectomy is the treatment of choice for symptomatic gallstones 1, 4
• Timing of surgery:
  • Early laparoscopic cholecystectomy (ELC) should be performed within 7 days of hospital admission and within 10 days of symptom onset 1
  • If ELC cannot be performed within this timeframe, delayed laparoscopic cholecystectomy (DLC) should be performed after 6 weeks from the first clinical presentation 1
  • ELC is preferable to intermediate laparoscopic cholecystectomy (performed between 7 days and 6 weeks) 1

Uncomplicated Cholecystitis

• Early laparoscopic cholecystectomy with one-shot antibiotic prophylaxis 1
• No post-operative antibiotics are necessary if source control is complete 1

Complicated Cholecystitis

• Laparoscopic cholecystectomy with antibiotic therapy for 4 days in immunocompetent and non-critically ill patients if source control is adequate 1
• Antibiotic therapy up to 7 days based on clinical conditions and inflammation indices in immunocompromised or critically ill patients 1

Alternative Management Options

For Poor Surgical Candidates

• Percutaneous cholecystostomy may be an option for acute cholecystitis in patients with multiple comorbidities who are unfit for surgery and don't improve with antibiotic therapy 1, 2
• Note that cholecystostomy is inferior to cholecystectomy in terms of major complications for critically ill patients 1, 2

Non-Surgical Options for Select Patients

• Oral bile acids (ursodeoxycholic acid) may be considered for patients who:
  • Are unfit for or refuse surgery 2, 5
  • Have small stones (<6 mm), radiolucent (cholesterol-rich) stones 2, 5
  • Have a patent cystic duct and functioning gallbladder 2, 5
• Dissolution rates are highest for stones <0.5 cm in diameter 2, 3

Special Considerations

Surgical Risk

• Mortality rates for cholecystectomy vary by age and comorbidities:
  • Low-risk women under 49: 0.054% 3
  • Men have approximately twice the surgical mortality rate of women 3
  • Mortality increases with age and presence of systemic disease 3

Conversion to Open Surgery

• Conversion from laparoscopic to open cholecystectomy is not a failure but a valid option when necessary for patient safety 1
• Risk factors for conversion include age >65 years, male gender, acute cholecystitis, thickened gallbladder wall, diabetes mellitus, and previous upper abdominal surgery 1

Complications

• Bile duct injury is a potential complication of laparoscopic cholecystectomy, making surgeon experience an important consideration 2, 6
• Spilled gallstones during laparoscopic cholecystectomy can lead to complications, with reported rates ranging from 0.04% to 19% 1

Common Pitfalls

• Ambiguous or atypical symptoms (indigestion, flatulence, heartburn, bloating) are less likely to resolve following cholecystectomy 2
• Approximately 30% of patients with a single episode of biliary pain may not experience additional episodes even with prolonged follow-up 2, 7
• Delaying cholecystectomy in mild gallstone pancreatitis beyond 4 weeks increases risk of recurrent attacks 2
• Failing to recognize that conservative management of symptomatic gallstones leads to recurrent gallstone-related complications in about 30% of patients, with 60% eventually requiring cholecystectomy 1
