Pediatric Inguinal Hernia Repair with Laparoscopy (PIHRL)-trial: A multicenter study comparing extra-corporeal Percutaneous Internal Ring Suture (PIRS) and intra-corporeal purse-string suture for inguinal hernia

Techniques for inguinal hernia repair (IHR) in children are continuously being improved. Open repair is increasingly giving way to laparoscopy, with two possible approaches for laparoscopy: extra-peritoneally (Percutaneous Internal Ring Suturing, PIRS) or intra-peritoneally (conventional laparoscopy with purse-string suture). The aim of this trial is to compare outcomes, e.g. recurrence and anesthesia times, of PIRS with intra-corporeal laparoscopy using a purse-string suture (LIHR).
