Treatment of Cholecystitis
Urgent laparoscopic cholecystectomy is the preferred treatment for acute cholecystitis and should be performed within 72 hours of diagnosis, with a possible extension up to 7-10 days from symptom onset. 1, 2
Diagnosis
Before initiating treatment, proper diagnosis is essential:
- Clinical features: Right upper quadrant pain, fever, and leukocytosis
- Imaging:
- Ultrasonography is first-line (sensitivity ~81%, specificity ~83%) 1
- Key findings: gallstones, gallbladder wall thickening, pericholecystic fluid, distended gallbladder, and positive sonographic Murphy's sign
- Hepatobiliary scintigraphy (HIDA scan) is the gold standard when ultrasound is inconclusive 1, 3
Treatment Algorithm
1. Initial Medical Management
- Fasting
- Intravenous fluid resuscitation (goal-directed therapy) 1
- Antimicrobial therapy:
- Pain management: NSAIDs as first-line, acetaminophen as alternative 1
2. Definitive Treatment
Early laparoscopic cholecystectomy (within 72 hours of diagnosis) 1, 2, 3
- Associated with fewer complications (11.8% vs 34.4% for delayed surgery)
- Shorter hospital stay (5.4 vs 10.0 days)
- Lower hospital costs 3
If surgery must be delayed beyond 10 days, it's better to wait at least 6 weeks after the clinical presentation 2
3. Alternative Treatments for High-Risk Patients
- Percutaneous cholecystostomy for critically ill patients unfit for surgery 4, 1, 5
- Note: Associated with higher complication rates (65%) compared to laparoscopic cholecystectomy (12%) 3
- Open cholecystectomy may be necessary in cases of severe inflammation, adhesions, or anatomical variations 1
- Mini laparotomy cholecystectomy may be appropriate in resource-constrained settings 4
Special Populations
Pregnant Women
- Early laparoscopic cholecystectomy is recommended during all trimesters
- Lower risk of maternal-fetal complications (1.6%) compared to delayed management (18.4%) 1, 3
Elderly Patients
- Laparoscopic cholecystectomy is associated with lower 2-year mortality (15.2%) compared to nonoperative management (29.3%) 3
- Careful monitoring of renal function and appropriate dose adjustments of medications 1
Acalculous Cholecystitis
- Represents 5-10% of cholecystitis cases 3
- Higher mortality rate (45.2%) compared to calculous cholecystitis (21.2%) 1
- Laparoscopic cholecystectomy is recommended except in severely ill patients, who may benefit from percutaneous cholecystostomy 3
Complications to Monitor
- Gangrenous cholecystitis
- Emphysematous cholecystitis
- Gallbladder perforation
- Hemorrhagic cholecystitis 1
Common Pitfalls and Caveats
- Delaying surgery beyond 72 hours increases complication rates
- Unnecessary prolonged antibiotic therapy increases the risk of resistance 1
- Bile duct injuries are among the most serious complications of laparoscopic cholecystectomy 6
- Concomitant conditions such as choledocholithiasis, cholangitis, and biliary pancreatitis must be recognized and adequately treated 2
The evidence strongly supports early laparoscopic cholecystectomy as the standard of care for acute cholecystitis, with appropriate medical management including antibiotics, fluid resuscitation, and pain control in the perioperative period.
