A 52-year-old woman with a 10-year history of cholelithiasis presents to the emergency department with acute onset right upper quadrant pain, fever (38.5°C), and a positive Murphy's sign. Ultrasound shows a thickened gallbladder wall (5 mm), pericholecystic fluid, and impacted stone in the Hartmann's pouch. Laboratory values: WBC 14,000/μL, bilirubin 1.2 mg/dL, AST 45 U/L. What is the most appropriate immediate next step in management?

Explanation

## Clinical Diagnosis This patient has **acute cholecystitis** confirmed by: - Classic triad: RUQ pain, fever, positive Murphy's sign - Ultrasound findings: thickened wall, pericholecystic fluid, impacted stone - Mild leukocytosis and normal/near-normal liver enzymes (uncomplicated acute cholecystitis) ## Management Algorithm for Acute Cholecystitis ```mermaid flowchart TD A[Acute cholecystitis confirmed]:::outcome --> B{Systemic toxicity/<br/>Complications?}:::decision B -->|No| C[IV fluids, antibiotics,<br/>analgesia]:::action C --> D[Early laparoscopic<br/>cholecystectomy<br/>within 72 hours]:::action B -->|Yes| E{High surgical<br/>risk?}:::decision E -->|No| F[Urgent/emergency<br/>cholecystectomy]:::action E -->|Yes| G[Percutaneous<br/>cholecystostomy]:::action D --> H[Resolution]:::outcome F --> H G --> I[Definitive surgery<br/>after stabilization]:::action ``` ## Key Point: **Early laparoscopic cholecystectomy (within 72 hours of symptom onset) is the gold standard for uncomplicated acute cholecystitis.** This reduces morbidity, hospital stay, and recurrent attacks compared to delayed surgery. ## High-Yield: The correct sequence is: 1. **Resuscitation**: IV fluids, electrolyte correction 2. **Antibiotics**: Broad-spectrum (ceftriaxone + metronidazole or piperacillin-tazobactam) 3. **Analgesia**: NSAIDs or opioids as needed 4. **Definitive treatment**: Laparoscopic cholecystectomy within 72 hours ## Clinical Pearl: This patient has no features of complicated cholecystitis (no sepsis, no signs of perforation, normal bilirubin, no acute pancreatitis). Therefore, she is a candidate for early laparoscopic surgery, not percutaneous drainage or medical management alone. ## Warning: ~~Delayed cholecystectomy (>10 days) increases risk of recurrent symptoms and conversion to open surgery.~~ Early surgery is preferred in fit patients. ## Indications for Percutaneous Cholecystostomy: - Unfit for surgery (APACHE score >15, severe sepsis, multiorgan failure) - Emphysematous cholecystitis - Perforated gallbladder with localized abscess - Acute cholecystitis in the setting of acute pancreatitis This patient does not meet these criteria.
