Laparoscopic cholecystectomy is a frequently performed surgical procedure and isconsidered the gold standard for treating symptomatic gallstone disease. Althoughlaparoscopic cholecystectomy is considered minimally invasive, it can cause moderate tosevere pain in the postoperative period. Poorly controlled early postoperative pain canimpair recovery quality and increase the risk of postoperative pulmonary complications asa risk factor for chronic pain development. Multimodal analgesia, including opioids, isused to limit pain following laparoscopic cholecystectomy. However, opioid treatment maylead to side effects such as postoperative nausea and vomiting (PONV), respiratorydepression, and constipation.Nerve blocks provide better pain control, reduce opioid consumption in the postoperativeperiod, and offer advantages such as fewer side effects and a lower risk of pulmonary andcardiac complications.In our clinic, a multimodal analgesia approach is preferred for patients undergoinglaparoscopic cholecystectomy. In addition to intravenous analgesic agents, peripheralnerve blocks are administered based on patient preference (for all eligible andconsenting patients).This study aims to compare the postoperative analgesic efficacy of the TransversusAbdominis Plane (TAP) Block and the Modified Thoracoabdominal Nerve Block with aPericostal Approach (M-TAPA) in patients undergoing laparoscopic cholecystectomy.Standard analgesic methods are applied to patients who do not consent to peripheral nerveblock administration.
