Summary

This study tests two different nerve blocks to see which one better reduces pain and the need for strong painkillers after laparoscopic gallbladder removal. Eighty adults having elective surgery will be randomly assigned to receive one of the two blocks. The main goal is to see how long it takes before they need extra pain medication.

What this could mean

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

Active substance: nerve block procedure (retrosuperior costotransverse ligament block or erector spinae block)
What this could lead to: If successful, this could identify a better nerve block technique to reduce opioid use and improve pain control after gallbladder surgery.
What could go wrong: This is a small, early-phase study (80 participants) comparing two established techniques, so any advantage may be modest or not apply to other surgeries or patient groups.
