title: Laparoscopic pediatric inguinal hernia repair: no ligation, just resection.
abstract: BACKGROUND
  There have been descriptions of several techniques for congenital inguinal hernia (CIH) repair in the pediatric population by doing high ligation of the sac, without a definitive advantage over the open procedure. High recurrence rates have been reported with using these minimally invasive techniques in which the patent processus vaginalis has been ligated and left in place completely or partially.
  
  
  METHODS
  With approval of the ethics committee, a proper informed consent was obtained. During July 2003 to April 2008, we performed the inguinal hernia repair on 91 patients (76 males and 15 females), using a laparoscopic technique in which we completely resected the patent processus vaginalis and the parietal peritoneum surrounding the internal inguinal ring. This allowed the peritoneal scar tissue to close the area of the ring. Also, this scarring occurs in the extent of the inguinal canal where the dissection took place, therefore causing the same peritoneal scarring and sealing of the inguinal floor. In this series, a purse string was done only in the cases with an internal ring wider than 10 mm.
  
  
  RESULTS
  There were no conversions. Operative time was in the range of 35-72 minutes (average, 40). Close follow-up in the clinic has been 5 months to 4 years without a single recurrence. In 4 cases, 3 months later, we did a laparoscopic evaluation of the contralateral side due to associated cryptorchidism, in which we were able to confirm a complete closure of the interior inguinal ring. Two small hematomas were followed until they were gone, without further need for intervention.
  
  
  CONCLUSIONS
  No recurrences have been observed. We conclude that laparoscopic repair of CIH is feasible using this technique of complete resection of the processus vaginalis and surrounding parietal peritoneum. This series does not conclude on the need for the internal ring to be closed when found to be wider than 10 mm.
