Laparoscopic inguinal hernia repair in children via PIRS (percutaneous internal ring suturing).

INTRODUCTION

The miniinvasive approach is a trend in pediatric surgery nowadays. The new surgical technique called percutaneous internal ring suturing (PIRS) is a promising method bringing all the benefits of miniinvasive surgery.

METHODS

Prospective study of patients operated on using the PIRS technique from 01 January 2018 to 01 January 2020 at the Department of Pediatric Surgery, 2nd Faculty of Medicine, Charles University, University Hospital Motol.

RESULTS

73 patients (25 boys and 48 girls) were operated on using PIRS. The median age was 68 months. 90 % of operations were performed by the same team of surgeons. During the procedure there were found 53 right-sided and 38 left-sided inguinal hernias. In 18 cases the hernia was bilateral, but only in 13 cases was this diagnosis made before the operation. A non-absorbable stitch was used in 57 cases to close the internal ring of the inguinal canal, and a non-absorbable monofilament in 16. The median operating time was 34 minutes. There were 3 recurrences (3.3 %) in our study.  Conclusion: In our initial study, the PIRS technique proved to be a safe alternative method to the open inguinal hernia surgery. This method provides the benefit of allowing to revise the contralateral inguinal canal as a prevention of a metachronous inguinal hernia. The cosmetic results were excellent.
