A 48-year-old man presents with acute right upper quadrant pain and fever (38.5°C). Ultrasound shows a distended gallbladder with a 2 cm stone impacted in the Hartmann pouch and pericholecystic fluid. Murphy's sign is positive. Laboratory tests reveal WBC 14,000/μL and mildly elevated liver enzymes. The patient is hemodynamically stable. What is the most appropriate immediate management?

Explanation

## Acute Cholecystitis: Initial Management Strategy ### Clinical Diagnosis **Key Point:** This patient has acute calculous cholecystitis (Murphy's sign positive, fever, elevated WBC, imaging findings). The impacted stone in the Hartmann pouch is the classic anatomical finding in acute cholecystitis. **High-Yield:** The Hartmann pouch is the most dependent part of the gallbladder fundus — stones commonly impact here, causing inflammation and obstruction of the cystic duct. ### Management Algorithm for Acute Cholecystitis ```mermaid flowchart TD A[Acute Cholecystitis]:::outcome --> B{Hemodynamically stable?}:::decision B -->|Yes| C[IV antibiotics + fluids + analgesia]:::action C --> D{Fit for early surgery?}:::decision D -->|Yes| E[Laparoscopic cholecystectomy within 72 hours]:::action D -->|No| F[Percutaneous cholecystostomy]:::action B -->|No| G[Resuscitate + ICU]:::urgent G --> H[Consider percutaneous drainage]:::action E --> I[Definitive treatment]:::outcome F --> J[Delayed cholecystectomy after 6-8 weeks]:::action ``` ### Why Early Cholecystectomy (Within 72 Hours) Is Standard | Timing | Outcome | Morbidity | |--------|---------|----------| | Early (<72 hrs) | Lower conversion rate, reduced complications | 5–10% conversion to open | | Delayed (>72 hrs) | Higher risk of recurrent cholecystitis, longer hospital stay | 15–20% readmission | | Percutaneous drainage | Reserved for unfit/septic patients | Requires second procedure | **Clinical Pearl:** In hemodynamically stable patients with uncomplicated acute cholecystitis, early laparoscopic cholecystectomy (within 72 hours of symptom onset) is superior to delayed surgery. It reduces inflammation, prevents progression to empyema or perforation, and shortens overall hospital stay. ### Role of Percutaneous Cholecystostomy Percutaneous cholecystostomy is indicated when: - Patient is septic or hemodynamically unstable - Unfit for surgery (critical comorbidities, high operative risk) - Elderly with multiple organ dysfunction - Delayed diagnosis with established complications (empyema, perforation) **Warning:** Percutaneous drainage is NOT first-line in a stable patient. It is a bridge to delayed surgery, not a definitive treatment. ### Why ERCP Is Not Indicated ERCP with sphincterotomy is for: - Choledocholithiasis (stones in the common bile duct) - Acute pancreatitis from biliary obstruction - Cholangitis This patient has uncomplicated acute cholecystitis (no evidence of CBD obstruction or pancreatitis) — ERCP is not indicated and delays definitive treatment. **Mnemonic: EARLY-STABLE** — Early cholecystectomy for Stable patients with Acute cholecystitis; Percutaneous drainage for unstable or unfit patients.
