Aim: To evaluate and compare the differences in recurrence rates of post inguinal hernia repair in children using Laparoscopic Intracorporeal Closure of the Processus Vaginalis (LICPV) and Percutaneous Internal Ring Closure (PIRS) operating techniques and compare them to published data.
Methods: A retrospective data analysis of children who underwent LICPV or PIRS techniques between 2005 and 2018 in the tertiary paediatric surgery department of university hospital was done. We analyzed demographic data, operating time, the influence of surgeon, recurrence rate, and the time until recurrence within an observed period of time post-operatively.
Results: A total of 240 patients underwent laparoscopic inguinal hernia repair procedures between 2005 and 2018. Of them 138 (57.5%) were male and 102 (42.5%) were female, with mean age of 6.48 (SD ± 4.7). LICPV method accounted for 170 (70.8%) inguinal hernia repairs, whilst 70 (29.2%) underwent the PIRS procedure. The overall recurrence rate was 8.3%; it was significantly higher in the PIRS group (18.6% versus 4.11%, p < 0.05). Males presented higher recurrence rates over females across both procedures. The mean time taken for any recurrence to happen was shorter in patients who underwent the PIRS method as opposed to LICPV techniques, 3.3 and 6.5 months, respectively (p > 0.05).
Conclusion: In our hands, a significantly higher recurrence rate exists for children undergoing the PIRS method over LICPV techniques when treating inguinal hernias.
