Although laparoscopic techniques are considered minimally invasive surgical procedures with lower perioperative pain scores compared to open surgeries, they are still associated with significant levels of pain. This study aims to investigate the analgesic effectiveness of two routinely performed regional analgesic techniques in our clinic-ultrasound-guided classic bilateral TAP block and ultrasound-guided bilateral M-TAPA block-in patients undergoing laparoscopic gyneco-oncologic surgery (LGOS), as well as their effects on intraoperative opioid consumption.
