From the Guidelines
The management of acute cholecystitis should prioritize early laparoscopic cholecystectomy within 24-72 hours of diagnosis, as it reduces overall hospital stay and complications compared to delayed surgery, as recommended by the most recent guidelines 1.
Initial Management
Initial management includes NPO status, IV fluids, and broad-spectrum antibiotics such as piperacillin-tazobactam 3.375g IV q6h, ceftriaxone 1-2g IV daily plus metronidazole 500mg IV q8h, or ciprofloxacin 400mg IV q12h plus metronidazole 1. Pain should be controlled with NSAIDs or opioids like morphine 2-4mg IV q4h as needed.
Definitive Treatment
The definitive treatment for acute cholecystitis is early laparoscopic cholecystectomy, which should be performed as an urgent procedure with short course postoperative antibiotic therapy (1–4 days) for Class A or B patients with complicated acute cholecystitis 1. For Class C patients fit for surgery with complicated acute cholecystitis, cholecystectomy should be performed as an emergent procedure with postoperative antibiotic therapy.
Alternative Options
For patients who are poor surgical candidates, percutaneous cholecystostomy tube placement may be considered as a temporary decompression measure, although it is inferior to cholecystectomy in terms of major complications for critically ill patients 1.
Supportive Care
Supportive care includes antiemetics like ondansetron 4mg IV q8h and correction of electrolyte abnormalities. Early surgical consultation is essential for all patients with suspected cholecystitis.
Key Considerations
- Early laparoscopic cholecystectomy is the recommended treatment for acute cholecystitis, as it reduces overall hospital stay and complications compared to delayed surgery 1.
- Antibiotic therapy should be tailored to the individual patient's needs, with a short course of 1-4 days for most patients 1.
- Percutaneous cholecystostomy tube placement may be considered as a temporary measure for patients who are poor surgical candidates, but it is not a substitute for definitive surgical treatment 1.
From the Research
Management of Acute Cholecystitis
The management of acute cholecystitis involves a combination of supportive care, antibiotic therapy, and surgical intervention. The initial therapy is directed towards general support of the patient, including fluid and electrolyte replacement, correction of metabolic imbalances, and antibacterial therapy 2.
Antibiotic Therapy
Antimicrobial therapy is usually empirical and should cover the Enterobacteriaceae, in particular Escherichia coli 2. Coverage of anaerobes, such as Bacteroides spp., is warranted in patients with previous bile duct-bowel anastomosis, in the elderly, and in patients in serious clinical condition 2.
Surgical Intervention
Early laparoscopic cholecystectomy (ELC) is considered the best treatment for acute cholecystitis, with the optimal timeframe for performing ELC being within 72 hours from diagnosis 3. In patients who are not eligible for ELC, surgery may be delayed for at least 6 weeks after the clinical presentation 3.
Alternative Treatments
For patients who are unfit for surgery, alternative treatments such as percutaneous or endoscopic gallbladder drainage (GBD) may be considered 3, 4. These treatments can be used as a bridge to surgery or as a definitive treatment in patients with high operational risks 4.
Key Considerations
- Relief of biliary obstruction is mandatory, even if there is clinical improvement with conservative therapy 2.
- Emergency invasive therapy is reserved for patients who fail to show a clinical response to antibacterial therapy within the first 36 to 48 hours or for those who deteriorate after an initial clinical improvement 2.
- Immediate surgery is indicated for gangrenous cholecystitis and perforation with peritonitis 2.
- The use of antibiotics in the conservative management of acute calculous cholecystitis is not recommended, unless there are signs of infection 5.
Special Populations
Special consideration should be given to certain populations, such as:
- Pregnant women
- Cirrhotic patients
- Elderly patients These patients may require a tailored approach to management, taking into account their individual needs and risks 3, 4.
Treatment Outcomes
The success rate of antibiotics in the treatment of acute calculous cholecystitis is variable, with pooled event rates of 15% for the need for emergency intervention and 10% for recurrence of acute cholecystitis 5. The use of antibiotic therapy, drainage, or analgesic agents as a bridge to surgery is feasible, but it should be regarded as a temporary solution rather than a definitive treatment due to the frequent recurrence of symptoms and complications 6.
