Pain Management After Pancreatectomy

Immediate Postoperative Period

Mid-thoracic epidural analgesia (T5-T8) provides superior pain relief and fewer respiratory complications compared to IV opioids in major abdominal surgery, and should be continued for 48 hours postoperatively before transitioning to oral medications, as recommended by the American College of Surgeons 1
If epidural cannot be used, IV PCA with opioids, such as hydromorphone, is a suitable alternative, with moderate evidence showing that intravenous lidocaine infusion reduces pain intensity compared to PCA morphine alone 1

The American Pain Society recommends transitioning to oral multimodal analgesia combining scheduled opioids, acetaminophen, and NSAIDs (if no contraindications) after 48 hours of epidural, with aggressive management of opioid side effects including prophylactic laxatives 1
Oral morphine is recommended as the first-line strong opioid, with paracetamol/acetaminophen and NSAIDs or COX-2 inhibitors used around-the-clock, and rescue doses of immediate-release opioid available up to hourly 1, 2

The National Comprehensive Cancer Network recommends converting to extended-release oral formulation (morphine, oxycodone) or transdermal fentanyl once the 24-hour opioid requirement is stable, with continued use of immediate-release formulation for breakthrough pain 3
Laxatives should be prescribed routinely for prevention and management of opioid-induced constipation, and metoclopramide or antidopaminergic drugs used for opioid-related nausea/vomiting, as recommended by the American Gastroenterological Association 1

The American Society of Anesthesiologists recommends adding adjuvant medications, such as gabapentin, pregabalin, nortriptyline, or duloxetine, for neuropathic components of pancreatic pain 1
Celiac plexus block is indicated for pancreatic/upper abdominal pain failing systemic therapy, providing pain relief lasting 3-6 months, and can be performed percutaneously, laparoscopically, endoscopically, or via open surgical approach, as recommended by the American Society of Regional Anesthesia and Pain Medicine 1, 2, 4, 5

The American College of Surgeons recommends avoiding NSAIDs in patients with acute kidney injury or high renal risk, and using all opioids with caution at reduced doses and frequency in renal impairment, with fentanyl and buprenorphine being the safest options for chronic kidney disease stages 4-5 1
The National Comprehensive Cancer Network recommends considering interventional options, such as intrathecal opioid administration, for intolerable sedation, confusion, or inadequate pain control with systemic opioids, with significant opioid dose reduction potentially required to avoid oversedation 4, 5, 6
