This randomized clinical trial aims to evaluate and compare the analgesic efficacy of the Intertransverse Process Block (ITPB) and the Subcostal External Oblique Intercostal Plane Block (EOIPB) in patients undergoing laparoscopic sleeve gastrectomy. The primary outcome is the Visual Analog Scale (VAS) score within the first 24 hours after surgery. Secondary outcomes include total opioid consumption, requirement for rescue analgesia, block-related complications and adverse effects (hematoma, pneumothorax, local anesthetic systemic complications, vascular puncture, and infection), patient satisfaction assessed using a Likert scale, quality of recovery assessed using the QoR-15 questionnaire, and incidence of postoperative nausea and vomiting.
