Pain Management in Hemorrhoidectomy

Introduction to Opioid Therapy

  • Morphine is the reference strong opioid in the postoperative period, available in IV and oral formulations, with the oral route preferred when possible, as recommended by the American Society of Anesthesiologists 1
  • Oxycodone has clinical efficacy equal to morphine and is often used as take-home medication for continued pain management, with a specific dosage ratio, as recommended by the American Pain Society 1
  • Hydrocodone, often combined with acetaminophen, is commonly prescribed as a supply opioid for breakthrough pain, as suggested by the World Health Organization 2

Non-Opioid Analgesics and Adjuncts

  • Acetaminophen (paracetamol) is effective as an analgesic when used in combination with NSAIDs or morphine, reducing opioid use, and should be administered on a scheduled basis, according to the American College of Surgeons 2
  • NSAIDs are indicated for moderate pain when used alone, reduce morphine consumption and related side effects, but should be used with caution in patients with renal impairment, as advised by the National Kidney Foundation 2
  • Gabapentinoids (gabapentin, pregabalin) can be considered as components in multimodal analgesia, as recommended by the American Academy of Pain Medicine 2
  • Dexamethasone IV at 8 mg and ketamine in small doses can be used to reduce postoperative pain, according to the Society of Anesthesia and Sleep Medicine 1

Special Considerations

  • Patients on buprenorphine therapy may require higher than normal doses of opioids to treat pain for 2-4 days post-surgery, and multimodal analgesia and regional techniques are especially important in these patients, as suggested by the American Society of Addiction Medicine 3
  • Opioid side effects are dose-dependent, and at high doses, they can induce hyperalgesia, according to the World Health Organization 2

Multimodal Approach and Complications

  • Implementing a multimodal approach with scheduled administration of analgesics can significantly reduce the overall opioid requirement while maintaining effective pain control after hemorrhoidectomy, as recommended by the American College of Surgeons 2
  • Postoperative pain management for hemorrhoidectomy typically requires narcotic analgesics for 2-4 weeks, with most patients unable to return to work during this period, and stapled hemorrhoidopexy generally causes less pain than conventional hemorrhoidectomy 4
  • Potential complications of hemorrhoidectomy include:
  • Local anesthetics, such as injection at the operative site, can provide temporary relief, and the American Society of Colon and Rectal Surgeons may recommend multi-modal pain management approaches for optimal pain control 4
