New nerve block aims to cut opioid use after colon surgery
NCT ID NCT07351994
First seen Jan 21, 2026 · Last updated Jun 22, 2026 · Updated 23 times
Summary
This study will observe 400 adults having minimally invasive left-sided colorectal surgery to see if an extra nerve block during the operation can reduce pain and the need for opioids. The block targets nerves that carry pain signals from the internal organs. Researchers will track opioid use, nausea, pain scores, and hospital stay length to see if this technique improves recovery.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Autonomic neural field block (nerve block with local anesthetic)
What this could lead to
If successful, this nerve block could become a standard way to reduce visceral pain and opioid use after colorectal surgery, speeding recovery.
What could go wrong
This is an early observational registry, not a randomized trial. The nerve block may not provide significant benefit over standard care, and there are always risks with any procedure.
Conditions
