Laparoscopic total extraperitoneal groin hernia repair in females: comparison of outcomes between preservation or division of the uterine round ligament

Abstract

Background: Laparoscopic repair has been recommended as the method-of-choice of groin hernia repair among women. Whether the round ligament of uterus should be divided to facilitate mesh placement remains controversial. This study aims to review the outcomes of laparoscopic total extraperitoneal (TEP) groin hernia repair in women and to evaluate the impact of division of round ligament.

Methods: Consecutive female patients with inguinal or femoral hernias who underwent elective laparoscopic TEP repair at a single institution from 2006 to 2017 were included for retrospective analysis. Primary outcomes were postoperative pain, genital prolapse, and recurrence. Outcomes of patients who had the round ligament divided were further compared with those with round ligament preserved and multivariable adjusted analysis was performed.

Results: Sixty-eight patients with a total of 77 TEP repairs were included in the 12-year study period. The mean age was 45 ± 16 years old. Incidental femoral hernia was identified in 4 patients (5.9%). There was 1 (1.3%) recurrence upon mean follow-up of 42.9 ± 37.3 months. The round ligament was divided in 67.5% of patients, and upon multivariable adjusted analysis, there were no statistically significant differences in outcomes in terms of chronic pain (odds ratio [OR] = 2.210, P = .357), paresthesia (OR = 0.241, P = .149), and genital prolapse (OR = 0.327, P = .415) when compared with patients with preserved round ligament.

Conclusion: Laparoscopic groin hernia repair in women is associated with low recurrence. Division of round ligament intraoperatively facilitates mesh placement and has minimal impact on clinical outcomes.
