Laparoscopic liver resection became more popular performing in patients with liver tumors due to comparable several advantages with open liver section. Recently, the use of truncal nerve block combined with intravenous analgesic is the alternative technique to reduce postoperative pain after laparoscopic liver resection. Quadratus lumborum block was developed for perioperative analgesia in hip surgery and lower abdominal surgery.However, the appropriate strategies for postoperative pain manageme
