Evidence-based postoperative pain management after laparoscopic colorectal surgery

Area of Science:

• Anesthesiology
• Surgical Pain Management
• Colorectal Surgery

Background:

• Postoperative pain is a significant concern following laparoscopic colorectal surgery.
• Effective pain management is crucial for patient recovery and improved outcomes.

Purpose of the Study:

• To systematically review the literature on pain management strategies after laparoscopic colorectal surgery.
• To evaluate the efficacy and adverse effects of various analgesic and anesthetic interventions.

Main Methods:

• Systematic review of randomized controlled trials published between January 1995 and July 2011.
• Searched Embase and MEDLINE databases for studies on adult laparoscopic colorectal surgery.
• Assessed analgesic and anesthetic interventions, focusing on pain scores and adverse effects.

Main Results:

• Twelve studies were included from 170 identified randomized trials.
• Various interventions including ketorolac, methylprednisolone, ropivacaine, lidocaine infusion, intrathecal morphine, and epidural analgesia improved pain relief and bowel function.
• Significant heterogeneity in study designs precluded quantitative analysis; however, epidural analgesia showed acceptable pain scores.

Conclusions:

• Recommended: Local anesthetic infiltration, systemic steroids, NSAIDs/COX-2 inhibitors with paracetamol, and opioid rescue.
• Intravenous lidocaine infusion is recommended but not as first-line therapy.
• Neuraxial blocks (epidural, spinal morphine) are not recommended due to unfavorable risk:benefit ratio.
