New pain block could cut opioid use after abdominal surgery
NCT ID NCT07331441
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new nerve block called the External Oblique Intercostal Plane Block (EOIB) to see if it reduces pain and the need for opioids after major upper abdominal surgery. 78 adults having laparoscopic surgery on the stomach, liver, gallbladder, or pancreas will be randomly assigned to receive either the block plus standard pain care or standard care alone. The main goal is to measure total opioid use 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
External Oblique Intercostal Plane Block (EOIB) with ropivacaine
What this could lead to
If it works, this could provide a safer, more effective way to manage pain after major abdominal surgery, reducing opioid use and speeding recovery.
What could go wrong
This is a small, early-stage trial (78 participants). The block may not reduce pain significantly, and there is a risk of side effects like bleeding or infection at the injection site.
