Comparing pain relief methods for liver surgery patients

Randomized, Unblinded, Phase III Trial of Thoracic Epidural Analgesia Versus Four-Quadrant Transversus Abdominus Plane Block in Oncologic Open-Incision Liver Surgery

Phase 3 Interventional M.D. Anderson Cancer Center · NCT03214510

This study tests which pain relief method works better for people having liver surgery, comparing a spinal block to a different type of pain control to see which helps them recover faster and stay in the hospital for a shorter time.

What this trial studies

This phase III trial evaluates the effectiveness of thoracic epidural analgesia versus four-quadrant transversus abdominus plane block in reducing pain for patients undergoing open liver resection. Patients are randomly assigned to receive either thoracic epidural analgesia or a TAP block before surgery, with the primary goal of comparing hospital stay lengths. Secondary objectives include assessing postoperative pain scores, complication rates, and recovery outcomes between the two methods.

Who should consider this trial

Good fit: Ideal candidates are patients scheduled for open liver resection without bowel resection for malignancy at MD Anderson Cancer Center.

Not a fit: Patients with severe uncontrolled systemic diseases or chronic narcotic use may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved pain management and faster recovery for patients undergoing liver surgery.

How similar studies have performed: Previous studies have shown varying success with similar analgesic techniques, but this specific comparison is novel.
