Which pain block wins for liver surgery? new trial aims to find out

NCT ID NCT07615231

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study compares two ultrasound-guided nerve blocks—the External Oblique Intercostal (EOI) block and the Subcostal Transversus Abdominis Plane (TAP) block—for pain relief after minimally invasive liver surgery. 140 adults will be randomly assigned to receive one of the blocks with a local anesthetic. The main goal is to see which block reduces opioid use in the first 24 hours after surgery. The trial also tracks pain scores, nausea, and recovery time.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Ropivacaine (a local anesthetic) injected via two different nerve block procedures

What this could lead to

If one block works better, it could lead to less opioid use and faster recovery after minimally invasive liver surgery.

What could go wrong

This is a small, early-stage trial (140 people) comparing two established techniques, so the difference may be small or not apply to all patients.
