New Long-Lasting numbing shot could ease hemorrhoid surgery pain
NCT ID NCT07442539
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a long-acting numbing drug called liposomal bupivacaine can control pain for up to 72 hours after hemorrhoid surgery better than standard numbing medicine. About 156 adults having hemorrhoid surgery will receive either the long-acting drug or regular bupivacaine injected into the surgical area. The main goal is to see if patients need less rescue pain medication in the first 48 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
- liposomal bupivacaine (a long-acting numbing drug)
- What this could lead to
- If it works, this could provide a simpler, longer-lasting way to manage pain after hemorrhoid surgery, reducing the need for strong painkillers.
- What could go wrong
- This is an early-stage trial with only 156 people, so results may not apply to everyone. The drug may not work better than standard care, and side effects like allergic reactions or nerve issues are possible.
