Acute Cholecystitis Management

Initial Medical Management

• The American College of Surgeons recommends early laparoscopic cholecystectomy within 72 hours of diagnosis for acute cholecystitis, with initial medical management using antibiotics, intravenous hydration, and fasting 1, 2, 3

Antibiotic Therapy

• For uncomplicated cholecystitis in stable, immunocompetent patients, the first-line antibiotic is amoxicillin/clavulanate 2g/0.2g IV every 8 hours, with alternatives including ceftriaxone plus metronidazole or ticarcillin/clavulanate 4, 5
• For complicated cholecystitis or critically ill/immunocompromised patients, the first-line antibiotic is piperacillin/tazobactam 4g/0.5g IV every 6 hours or 16g/2g in continuous infusion, with alternatives including ertapenem or tigecycline 4, 5

Postoperative Antibiotic Duration

• For uncomplicated cholecystitis with complete source control, no postoperative antibiotics are required 2, 4, 3, 5
• For complicated cholecystitis with adequate source control, the maximum duration of antibiotic therapy is 4 days for immunocompetent patients and 7 days for immunocompromised or critically ill patients 5

Special Situations

• For concomitant choledocholithiasis or cholangitis, endoscopic retrograde cholangiopancreatography (ERCP) is recommended for biliary decompression, and magnetic resonance cholangiography (MRC) may be considered for evaluating the common bile duct 6, 5, 4
• For patients who are not candidates for surgery, percutaneous cholecystostomy is a safe and effective alternative 2, 6, 3

Surgical Timing and Adjunctive Management in Acute Cholecystitis

Timing of Definitive Cholecystectomy

• Early laparoscopic cholecystectomy should be performed within 72 hours of diagnosis, and surgery may still be safely scheduled up to 7–10 days after symptom onset when patients are fit for surgery. 7

Post‑operative Antibiotic Strategy

• In patients with uncomplicated acute cholecystitis who achieve complete source control, postoperative antibiotics are not required. 7
• For patients with complicated acute cholecystitis, a short postoperative antibiotic course of 1–4 days is recommended after source control. 7

Management of High‑Risk (Class C) Patients

• Critically ill but surgically fit patients should undergo emergent or urgent laparoscopic cholecystectomy combined with postoperative antibiotic therapy. 7

Indications for Percutaneous Cholecystostomy

• Percutaneous cholecystostomy is reserved for patients with multiple comorbidities who do not improve after 3–5 days of appropriate antibiotic therapy. 7

Management of Concomitant Biliary Pathology

• When choledocholithiasis or cholangitis is present, endoscopic retrograde cholangiopancreatography (ERCP) should be performed for biliary decompression. 7

Damage‑Control Approach in Severe Sepsis

• In the setting of severe hemodynamic instability with diffuse intra‑abdominal infection, a damage‑control surgical procedure should be considered irrespective of patient class. 7
