New nerve block may ease pain after gallbladder removal
NCT ID NCT06712498
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a specific nerve block, called the external oblique intercostal plane block, can reduce pain and improve satisfaction in patients undergoing laparoscopic gallbladder removal. Sixty-four adults aged 18-65 received either the nerve block with bupivacaine or no block. Researchers measured pain scores and how much pain medication patients needed 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
- Bupivacaine
- What this could lead to
- If successful, this nerve block could become a standard way to manage pain after gallbladder surgery, reducing the need for strong painkillers.
- What could go wrong
- This is a small, completed study with only 64 participants. The results may not apply to all patients, and nerve blocks carry rare risks like infection or bleeding.
