The aim of this study is to detect weather peritoneal block or erector spinae plane block will provide the most ideal analgesia for patients undergoing laparoscopic cholecystectomy. Peritoneal block by instillation of local anesthetic into the peritoneal cavity will act by blocking the free afferent nerve endings in the peritoneum and the systemic absorption of local anesthetic from the peritoneal cavity may also play a part in reduced pain. On the other hand ,the erector spinae plane block is a novel analgesic technique that provide both visceral and somatic analgesia due to its communication with the paravertebral space. Local anesthetic mixture of lidocaine , magnesium sulphate and epinephrine will be used for both techniques.
