Postoperative pain after laparoscopic cholecystectomy can be considerable. Regional techniques such as erector spinae plane (ESP) block or transversus abdominis plane (TAP) block may be suitable for patients at increased risk of postoperative pain. The deep rectus sheath block is a novel block which is a modified version of the conventional rectus sheath block. It was reported in a few case reports that, it may be used for postoperative analgesia in patients undergoing laparoscopic cholecystectomy. The aim of this study is to investigate the postoperative analgesic efficacy of deep rectus sheath block in patients undergoing laparoscopic cholecystectomy.
