Pediatric femoral hernia in the laparoscopic era

Abstract

Introduction

Femoral hernia is a rare and often misdiagnosed condition in childhood. The aim of our study was to demonstrate that the laparoscopic approach improves diagnostic accuracy and offers a safe and effective treatment.

Methods

A retrospective study of 687 pediatric patients who underwent laparoscopic inguinal hernia repair from January 2000 to December 2015 was performed.

Results

Femoral hernias were identified in 16 patients (2.3%). The right side was affected in 10 cases (62.5%), the left side in 5 (31.2%), and 1 case was bilateral (6.2%). The mean age of patients was 8.00 ± 3.81 years, and there was a male predominance. Preoperative diagnosis was femoral hernia in eight cases (50%) and indirect inguinal hernia in the remaining eight (50%). Seven children (43.8%) presented with hernia recurrence after having undergone an open ipsilateral indirect hernia repair. A modified laparoscopic McVay technique was performed in 12 cases (70.6%). An epigastric artery injury by trocar occurred in one patient. All operations were completed laparoscopically. The mean surgical time was 45.6 ± 22.9 min for unilateral cases and 110 ± 10.0 min for bilateral cases. No immediate postoperative complications were noted. The mean postoperative hospital stay was 0.6 ± 0.4 days. No recurrence was observed after a median follow-up of 11 years (range, 4–16 years).

Conclusion

Femoral hernia is a rare pathology in pediatric patients that is often difficult to diagnose. The laparoscopic approach is effective in the diagnosing and treating these hernias, and it allows for the simultaneous repair of multiple groin defects.
