Laparoscopic cholecystectomy is one of the most frequently performed abdominal surgical procedures worldwide. Despite minimally invasive techniques, postoperative pain remains a significant clinical problem due to port-site trauma, pneumoperitoneum, diaphragmatic irritation, and visceral manipulation.\n\nInadequate pain control may lead to impaired respiratory mechanics, reduced mobilization, delayed recovery, and an increased risk of postoperative pulmonary complications. Postoperative pulmonary dysfunction is a common consequence of upper abdominal surgery and may persist for several days, contributing to reductions in forced vital capacity (FVC) and forced expiratory volume in one second (FEV1), which are associated with increased postoperative morbidity.\n\nAlthough opioid-based analgesia is widely used, it is associated with adverse effects such as respiratory depression, nausea, vomiting, ileus, and delayed recovery. Therefore, regional anesthesia techniques and multimodal analgesia strategies are increasingly recommended to reduce opioid consumption while improving pain control.\n\nESPB and M-TAPA are ultrasound-guided fascial plane blocks used for postoperative analgesia in abdominal surgery. ESPB provides somatic and visceral analgesia through the spread of local anesthetic affecting the spinal nerve rami, while M-TAPA targets the anterior branches of the thoracoabdominal nerves to provide extensive anterior and lateral abdominal wall analgesia.\n\nDespite their increasing use, there is limited high-quality comparative evidence evaluating the effects of ESPB and M-TAPA on postoperative pulmonary function and opioid consumption in laparoscopic cholecystectomy. This study compares these two regional anesthesia techniques in a randomized controlled design to evaluate their impact on postoperative respiratory function and analgesic requirements.",[69,70],"Pulmonary Function","Post Operative Pain Control","NOT_YET_RECRUITING","2026-06-18",{"date":74,"type":75},"2026-06-24","ACTUAL",{"date":77,"type":63},"2026-07-01",{"date":79,"type":63},"2027-03-01",{"name":5,"class":6},1]
