Summary

This study looked at whether a specific nerve block (external oblique intercostal block) can reduce pain after laparoscopic sleeve gastrectomy, a weight-loss surgery. Twenty patients aged 18-65 participated. Researchers measured how much the block numbed the belly area and how much pain medicine patients needed in the first 24 hours after surgery. The goal was to improve comfort and reduce side effects like nausea.
