Efficacy of intravenous versus intraperitoneal lidocaine for postoperative analgesia in laparoscopic cholecystectomy: a randomized, double-blind, placebo-controlled trial.

Background: Laparoscopic cholecystectomy (LC) has become the gold standard for gallbladder removal due to the low degree of invasiveness. However, postoperative pain still persists. Local anesthetics provide analgesia, reduce opioid consumption, and accelerate the return of bowel activity with a rare incidence of toxicity.
