Overview

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.

Conditions

Gynecologic Laparoscopic Surgery Regional Anesthesia Block

Interventions

Patients in the TAP group will receive a bilateral Transversus Abdominis Plane (TAP) block under ultrasound guidance prior to surgery after general anaesthesia, with the local anesthetic administered between the internal oblique and transversus abdominis muscles. A total of 40 mL of 0.25% bupivacaine will be used for the procedure.

M-TAPA Block groupPROCEDURE

Patients in the M-TAPA group will receive a bilateral Thoracoabdominal Nerve Block through Perichondrial Approach (M-TAPA) under ultrasound guidance prior to surgery after general anaesthesia. A total of 40 mL of 0.25% bupivacaine will be used for the procedure.

Outcomes

Primary Outcomes

Evaluation of intraoperative opioid consumption

Time frame: during surgery

Secondary Outcomes

Comparison of postoperative Visual Analog Scale (VAS) pain scores

VAS is an eleven-scale pain score scored from 0 to 10, with vas 0 being no pain and vas 10 being maximum pain.

Time frame: postoperative first day
