NCT ID NCT07654556

First seen Jun 20, 2026 · Last updated Jun 20, 2026

Summary

This study will compare two types of nerve blocks (M-TAPA and ESP block) to see which provides better pain relief after laparoscopic sleeve gastrectomy. Sixty-four patients will receive an injection of the numbing medicine bupivacaine in one of the two block techniques. Pain scores will be measured for 48 hours after surgery to determine which approach is more effective.

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 one block proves better, it could improve pain control and reduce opioid use after weight-loss surgery.

What could go wrong

This is a small, early-stage study with only 64 participants, so results may not apply to all patients. Both blocks are already used, so no major breakthrough is expected.
