This randomized controlled study aims to evaluate the effectiveness of the bilateral rectointercostal fascial plane (RIB) block for postoperative pain management in patients undergoing laparoscopic sleeve gastrectomy. The study compares RIB block combined with standard general anesthesia to standard intravenous patient-controlled analgesia alone. The primary outcome is total opioid consumption within the first 24 postoperative hours, while secondary outcomes include pain scores, patient satisfaction, postoperative nausea and vomiting, and block-related complications.
