New study aims to find best pain block for gallbladder surgery
NCT ID NCT06900413
First seen Jun 26, 2026 · Last updated Sep 18, 2026 · Updated 1 time
Summary
This study compares two types of nerve blocks—ESP and EXORA—for managing pain after laparoscopic gallbladder removal. Fifty-six adults having elective surgery will be randomly assigned to receive one of the blocks. The goal is to see which block provides better pain relief and reduces the need for additional painkillers in the first 24 hours after surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- nerve block (local anesthetic injection)
- What this could lead to
- If one block works better, it could become the standard for reducing pain after gallbladder surgery, helping patients recover faster with less medication.
- What could go wrong
- This is a small, early-stage trial with only 56 people. The results may not apply to everyone, and nerve blocks carry rare risks like infection or allergic reaction.
