To explore the experience of single-port laparoscopic inner ring ligation using two-hooked core needle for recurrent inguinal hernia in children.

The clinical data of 1 056 children underwent laparoscopic inguinal hernia repair in the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed from January 2015 to January 2018. 32 cases presented recurrent inguinal hernia, in which the two-hooked core needle with ligated suture was punctured into the extraperitoneal space and the inner ring of the peritoneum was ligated by water separation technique. In the huge hernias, after the inner ring closure was completed, the hernia needle with a suture was inserted at identical subcutaneous path and the suture was left after penetrating the ipsilateral medial umbilical fold, then the needle without suture was re-introduced into abdomen through lateral extraperitoneal space and the suture at bottom of medial umbilical fold was grabbed and extracorporeal ligated. So the closed orifice area was additionally reinforced.

38 hernias of 32 cases were successfully ligated, 6 cases of contralateral recessive hernia were done simple internal ligation at the same time. 6 cases with large hernia underwent internal ligation aditional umbilical medial fold covering. The operative time of unilateral and bilateral inguinal hernia was (12.2±2.3) minutes and (15.2±2.5) minutes respectively. No complications occurred. All patients were followed up during 2 months to 3 years, without recurrence.

Laparoscopic percutanous extraperitoneal closure using the two-hook hernia needle with hydrodissection is a safe and effective technique. It is the prior option procedure for recurrent inguinal hernia in childeen.
