Ultrasound-guided pediatric inguinal hernia repair

Abstract

Purpose: Inguinal hernias are amongst the most common surgical conditions in children. Typically, these repairs are performed through an open or laparoscopic approach, using a high ligation of the hernia sac. The use of ultrasound has been described in identifying and evaluating hernia contents in children. Our goal was to determine if ultrasound guidance could be used to perform a high ligation of the hernia sac in pediatric patients.

Methods: Following IRB approval, a retrospective review of all female patients at a single center undergoing ultrasound guided inguinal hernia repair between 2017 and 2018 was performed. Pre-operative characteristics, intra-operative outcomes, and post-operative outcomes were all evaluated. Laparoscopy was used to evaluate the repair and evaluate for a contralateral hernia. Male patients did not undergo ultrasound inguinal hernia repair to avoid damage to the vas deferens and vessels.

Results: A total of 10 patients with 13 hernias total were found during the study period. A total of one patient was converted to a laparoscopic repair. No patients were found to have an inappropriate repair or a missed contralateral hernia, and there were no vascular injuries or injuries to surrounding structures. No patients had a hernia recurrence during the study period.

Conclusion: This study demonstrates the safety and feasibility of ultrasound guided inguinal hernia repairs in female pediatric patients. Further study is needed to compare these repairs to existing techniques, evaluate for recurrences over time, and evaluate if these repairs can be performed without general anesthetic in some patients.
