Laparoscopic cholecystectomy is associated with significant postoperative pain originating from trocar sites, pneumoperitoneum, and visceral irritation. Both local anesthetic infiltration and ultrasound-guided rectus sheath block are commonly used regional analgesic techniques to reduce postoperative pain and opioid consumption. This prospective randomized controlled study aims to compare the effects of these two techniques on postoperative pain scores, opioid requirements, and analgesia-related adverse effects following laparoscopic cholecystectomy.
