Pain Control in Chronic Pancreatitis

Initial Pharmacological Management

The American College of Physicians recommends starting with non-opioid analgesics (NSAIDs and acetaminophen) as first-line therapy for pain control in chronic pancreatitis, following a progressive analgesic ladder approach 1
Administering analgesics before meals can reduce postprandial pain and improve food intake in patients with chronic pancreatitis 1
The World Health Organization recommends avoiding NSAIDs in patients with acute kidney injury as they are contraindicated in this setting 2
Reserve stronger opioids (dilaudid, morphine, or fentanyl) for severe pain that fails to respond to weaker agents in patients with chronic pancreatitis 1, 2
Dilaudid is preferred over morphine or fentanyl in non-intubated patients with chronic pancreatitis 1, 2

The American Pain Society recommends adding gabapentin, pregabalin, nortriptyline, or duloxetine when pain has neuropathic characteristics in patients with chronic pancreatitis 3

The World Health Organization recommends integrating patient-controlled analgesia (PCA) with other pain management strategies for better control in patients with chronic pancreatitis 1, 2
Consider epidural analgesia as an alternative or adjunct to intravenous analgesia, particularly for patients requiring high-dose opioids for extended periods in chronic pancreatitis 1, 2
Switch to IV pain medications when oral routes are insufficient for severe pain in patients with chronic pancreatitis 1

The American Gastroenterological Association recommends ensuring strict abstinence from alcohol as the fundamental first step in pain management for patients with chronic pancreatitis 1

The European Society for Clinical Nutrition and Metabolism recommends providing pancreatic enzyme supplements to improve nutritional status and quality of life in patients with chronic pancreatitis, though evidence for direct pain relief is limited 1
Normal food with pancreatic enzyme supplementation is sufficient in most cases (>80% of patients) with chronic pancreatitis 1

The European Society of Gastrointestinal Endoscopy recommends considering endoscopic intervention for suboptimal surgical candidates or those preferring less invasive approaches for patients with chronic pancreatitis 1
For pancreatic duct stones ≤5mm: use conventional ERCP with standard stone extraction in patients with chronic pancreatitis 1
For larger stones: extracorporeal shockwave lithotripsy (ESWL) and/or pancreatoscopy with intraductal lithotripsy may be required in patients with chronic pancreatitis 1
For pancreatic duct strictures: prolonged stent therapy (6-12 months) with sequential upsizing of multiple plastic stents placed in parallel in patients with chronic pancreatitis 1

The American College of Surgeons recommends considering surgical intervention over endoscopic therapy for patients with painful obstructive chronic pancreatitis, as it provides superior long-term pain relief and quality of life 1
Longitudinal pancreaticojejunostomy is the most appropriate surgical procedure for chronic pancreatitis with pancreatic duct ectasia 1
Randomized trials demonstrate higher rates of complete or partial pain relief with early surgery compared to endoscopic therapy in patients with chronic pancreatitis 1

The American Gastroenterological Association recommends not relying on celiac plexus block as a first-line intervention - reserve for refractory cases only given the 40-50% failure rate in patients with chronic pancreatitis 1, 4, 5
Do not perform repeated celiac plexus injections - this increases risk of serious complications in patients with chronic pancreatitis 1
