Single-Incision Percutaneous Closure of Pediatric Inguinal Hernia: A New Modification for Intracorporeal Suture Knotting

Abstract

Background. Single-incision percutaneous closure (SIPC) of pediatric inguinal hernia under laparoscopic guidance is a well-developed feasible technique; however, suture knotting remains a major challenge during this technique. Most laparoscopic surgeons prefer extracorporeal subcutaneous suture knotting, which may be associated with consequent formation of stitch sinus and increased recurrence rate. On the other hand, intracorporeal suture knotting necessitates the availability of special devices or homemade instruments with a long learning curve. Therefore, the present study innovates new and simple modification allowing intracorporeal suture knotting during SIPC of pediatric inguinal hernia that does not require any special operating devices or homemade instruments. Patients and Methods. Four-hundred children suffering from inguinal hernia of congenital type, submitted to SIPC using Epidural needle (EN), under laparoscopic guidance with intracorporeal suture knotting. Results. Children ages were 6 months to 10 years (the range). There were 300 boys and 100 girls, and two-hundred children suffered from left side hernia, 150 with right-side hernia, and 50 children with both left- and right-side hernia. 10 ± 2.2 minutes was the recorded operation time in one side hernia repair, while 14 ± 4.3 minutes was recorded for both side repair. Postoperative results reported recurrent hernia in one child and postoperative hydrocele in 3 children which resolved spontaneously after 3 weeks of follow-up. Conclusion. Intracorporeal suture knotting during SIPC of pediatric inguinal hernia allows for the transformation of a formally extraperitoneal procedure to an intraperitoneal procedure. This new modification for intracorporeal suture knotting does not require any special operating devices or homemade instruments. It seems to be an attractive way during SIPC of pediatric inguinal hernia when intracorporeal suture knotting is considered.
