What is the management for a patient with cholecystitis and abdominal pain?

Management of Cholecystitis and Abdominal Pain

Early laparoscopic cholecystectomy (within 7-10 days of symptom onset) is the gold standard treatment for patients with acute cholecystitis presenting with abdominal pain. 1, 2

Clinical Presentation and Diagnosis

• Patients with acute cholecystitis typically present with abdominal pain in the right upper quadrant, which can be acute and intense 2
• Positive Murphy's sign (pain during palpation with deep inspiration) is a characteristic finding 2
• Fever, nausea, and abdominal tenderness are common accompanying symptoms 1, 2
• A palpable gallbladder mass may indicate complicated cholecystitis 2
• Laboratory findings often include leukocytosis and elevated C-reactive protein 2

Diagnostic Imaging

• Ultrasound is the first-line imaging modality for suspected acute cholecystitis (sensitivity ~81%, specificity ~83%) 2, 3
• Typical ultrasound findings include:
  • Pericholecystic fluid
  • Distended gallbladder
  • Edematous gallbladder wall
  • Gallstones (often impacted in cystic duct)
  • Sonographic Murphy's sign 1, 2
• CT with IV contrast can be used as an alternative when ultrasound is inconclusive 1
• MRCP (magnetic resonance cholangiopancreatography) is indicated when common bile duct stones are suspected 1, 2

Treatment Algorithm

Uncomplicated Cholecystitis

1. Early treatment (preferred approach):

   • Early laparoscopic cholecystectomy within 7-10 days of symptom onset 1, 2
   • Single-dose antibiotic prophylaxis at the time of surgery 1
   • No post-operative antibiotics needed 1, 2

2. Delayed treatment (second option):

   • Antibiotic therapy followed by planned delayed cholecystectomy 1
   • Antibiotic therapy for no more than 7 days 1, 4
   • Not recommended for immunocompromised patients 1

Complicated Cholecystitis

1. Surgical approach:

   • Laparoscopic cholecystectomy (with open cholecystectomy as an alternative) 1
   • Antibiotic therapy for 4 days in immunocompetent, non-critically ill patients if source control is adequate 1
   • Extended antibiotic therapy up to 7 days for immunocompromised or critically ill patients 1, 4

2. Alternative approach for high-risk patients:

   • Percutaneous cholecystostomy for patients with multiple comorbidities who are unfit for surgery 1, 5
   • Consider this option for patients who don't show clinical improvement after several days of antibiotic therapy 1
   • Note that cholecystostomy is inferior to cholecystectomy in terms of major complications for critically ill patients 4, 3

Antibiotic Therapy

For non-critically ill, immunocompetent patients:

• Amoxicillin/Clavulanate 2g/0.2g every 8 hours 1, 2

For patients with documented beta-lactam allergy:

• Eravacycline 1 mg/kg every 12 hours OR
• Tigecycline 100 mg loading dose, then 50 mg every 12 hours 2, 4

For critically ill or immunocompromised patients:

• Piperacillin/tazobactam 6 g/0.75 g loading dose, then 4 g/0.5 g every 6 hours or 16 g/2 g by continuous infusion 1, 4

Special Considerations

• Early laparoscopic cholecystectomy is associated with shorter hospital stays, fewer complications, and lower costs compared to delayed surgery 3
• Patients who continue to show signs of infection or systemic illness beyond 7 days of antibiotic treatment require additional diagnostic investigation 1, 4
• For high-surgical risk patients who undergo percutaneous cholecystostomy as a bridge to surgery, laparoscopic cholecystectomy should be performed at least six weeks after PC placement 5
• For patients not suitable for surgery (CCI ≥6 and ASA-PS ≥4), percutaneous cholecystostomy should remain in place for at least three weeks 5
• Elderly patients (>65 years) with acute cholecystitis benefit from laparoscopic cholecystectomy, which is associated with lower 2-year mortality (15.2%) compared to non-operative management (29.3%) 3

Pitfalls and Caveats

• Delayed surgical intervention can lead to increased morbidity and mortality, particularly in elderly or immunocompromised patients 1, 3
• Acalculous cholecystitis (without gallstones) accounts for up to 10% of cases and requires the same urgent approach to treatment 3
• Hemorrhagic cholecystitis, though uncommon, can be fatal and requires urgent surgical intervention, especially in patients on anticoagulant therapy 6
• Conversion from laparoscopic to open cholecystectomy should not be hesitated if technical difficulties arise during surgery 7
• Bile duct injuries are among the most serious complications of cholecystectomy and are often the result of inexperience or technical issues 7
