From the Guidelines
Pain management in acute cholecystitis should prioritize a multimodal approach, with NSAIDs as first-line therapy, and opioids such as morphine added for moderate to severe pain that doesn't respond adequately to NSAIDs, with the goal of minimizing morbidity, mortality, and improving quality of life. When considering the use of oral morphine in acute cholecystitis, it's essential to weigh the benefits and risks, particularly in terms of respiratory depression and constipation. However, in the context of acute pain management, the benefits of adequate pain control often outweigh these risks. The management of pain in acute cholecystitis typically involves:
- NSAIDs as first-line therapy, particularly ketorolac (30mg IV initially, then 15-30mg IV every 6 hours) or ibuprofen (400-800mg orally every 6-8 hours)
- Opioids such as morphine (2-4mg IV every 4 hours as needed) or hydromorphone (0.5-1mg IV every 4 hours as needed) for moderate to severe pain that doesn't respond adequately to NSAIDs
- Acetaminophen (1000mg orally or IV every 6 hours) as an adjunct to reduce opioid requirements
- Antispasmodics like hyoscine butylbromide (20mg IV/IM every 4-6 hours) to relieve biliary colic According to the 2020 World Society of Emergency Surgery updated guidelines for the diagnosis and treatment of acute calculus cholecystitis 1, surgery is currently the recommended treatment in people with acute cholecystitis, with laparoscopic cholecystectomy preferred over open cholecystectomy. The guidelines also suggest that early laparoscopic cholecystectomy (ELC) performed within 7 days of hospital admission and within 10 days of onset of symptoms is superior to either intermediate or delayed laparoscopic cholecystectomy 1. In terms of pain management, the guidelines do not specifically address the use of oral morphine, but they do emphasize the importance of multimodal pain management, including the use of NSAIDs, opioids, and other adjunctive therapies 1. Overall, the goal of pain management in acute cholecystitis is to minimize morbidity, mortality, and improve quality of life, while also preparing the patient for definitive treatment with cholecystectomy.

From the Research
Management of Pain in Acute Cholecystitis
The management of pain in acute cholecystitis typically involves the use of analgesics. According to a study published in 2008 2, non-steroid anti-inflammatory drugs (NSAIDs) are safer and more effective than other analgesics for treating biliary colic in adults.
Use of Oral Morphine
There is limited information available on the use of oral morphine specifically for acute cholecystitis. However, a study published in 1995 3 used morphine-enhanced radionuclide cholescintigraphy for the diagnosis of acute cholecystitis in critically ill patients. The study found that morphine-enhanced cholescintigraphy had an accuracy of 91%, sensitivity of 100%, specificity of 88%, positive predictive value of 75%, and negative predictive value of 100%.
Key Points to Consider
- The current standard of care for acute cholecystitis is early laparoscopic cholecystectomy with appropriate administration of fluid, electrolyte, and antibiotics 4, 5.
- Percutaneous cholecystostomy tube placement is an effective therapy for patients with exceptionally high perioperative risk 5.
- NSAIDs are the analgesics of choice in uncomplicated biliary colic, as they are more effective than other analgesics and can improve prognosis, limiting progression of colic to acute cholecystitis 2.
- Morphine-augmented radionuclide hepatobiliary imaging is superior to delayed imaging for the diagnosis of acute cholecystitis 6.
Treatment Options
- Early laparoscopic cholecystectomy
- Percutaneous cholecystostomy tube placement
- NSAIDs for pain management
- Morphine-enhanced radionuclide cholescintigraphy for diagnosis
