Summary

This study compared two types of nerve blocks—recto-intercostal and external oblique intercostal—for pain relief after laparoscopic gallbladder removal. Sixty adults having elective surgery received one of the two blocks. Researchers measured how much extra painkiller they needed and their pain scores over 24 hours.

What this could mean

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

Active substance
local anesthetic (nerve block)
What this could lead to
If one block works better, it could improve pain control and reduce opioid use after gallbladder surgery.
What could go wrong
This is a small, completed observational study, not a large trial. Results may not apply to all patients or surgeries.
