Laparoscopic Inguinal Hernia Repair

This randomized clinical trial aims to evaluate and compare the analgesic efficacy of the Transversalis Fascia Plane Block (TFPB) and the Modified Thoracoabdominal Nerve Block through Perichondrial Approach (M-TAPA) in patients undergoing laparoscopic inguinal hernia repair. The primary outcome is the Visual Analog Scale (VAS) score within the first 24 hours after surgery. Secondary outcomes include total opioid consumption, requirement for rescue analgesia, block-related complications and adverse effects (hematoma, local anesthetic systemic complications, vascular puncture, and infection), patient satisfaction assessed using a Likert scale, quality of recovery assessed using the QoR-15 questionnaire, and incidence of postoperative nausea and vomiting.

Transversalis Fascia Plane Block (TFPB) is a trunk block that blocks the T12- L2 spinal nerves by injection of local anesthetic between the transversus abdominis muscle and transversalis fascia on the lateral abdominal wall. The block's positive effects on postoperative analgesia have been shown in many abdominal surgeries, including open-technique inguinal hernia repair. This study aimed to investigate the effectiveness of ultrasound (US) guided TFPB on postoperative pain control for postoperative analgesia management after laparoscopic inguinal hernia repair.
