Abstract

Abstract

Objective: The optimal surgical approach for bilateral inguinal hernia repair remains controversial.This study aimed to compare the clinical outcomes of laparoscopic total extraperitoneal repair (TEP) and open Lichtenstein repair in patients undergoing elective bilateral inguinal hernia surgery.Methods: Patients who underwent elective surgery for bilateral inguinal hernia between January 2021 and December 2025 were retrospectively evaluated.Patients were divided into two groups according to the surgical technique: TEP and Lichtenstein repair.Demographic characteristics, perioperative findings, postoperative complications, recurrence, chronic pain, and length of hospital stay were compared between the groups.Results: A total of 264 patients were included in the study.Of these, 145 underwent TEP repair and 119 underwent Lichtenstein repair.Operative time was significantly shorter in the TEP group compared with the Lichtenstein group (73.4±26.8 vs. 101.2±35.2minutes, p<0.001).Overall morbidity rates were similar between the groups (22.1% vs. 30.3%,p=0.130).Chronic postoperative pain was significantly lower in the TEP group (2.8% vs. 8.4%, p=0.042).Although recurrence was numerically higher in the TEP group (6.9% vs. 3.4%), the difference was not statistically significant (p=0.202).No significant difference was observed in length of hospital stay (p=0.235).Conclusion: Both TEP and Lichtenstein repairs are safe and effective options for bilateral inguinal hernia surgery, with comparable morbidity and recurrence rates.However, TEP repair was associated with shorter operative time and lower chronic postoperative pain.Surgical approach should be individualized according to patient characteristics, anesthetic risk, and surgeon experience.
