Laparoscopic hernia repair in children is still controversial. The aim of this study was to report our long-term results of the laparoscopic hernia technique, which is based on the same surgical principles as conventional open herniotomy.
Five hundred fourteen pediatric patients with inguinal hernia were included in this study under informed consent. All patients underwent a laparoscopic technique of sac transection and intracorporeal ligation. The asymptomatic contralateral inguinal ring was routinely explored and repaired if a patient had patent processus vaginalis on the contralateral side. Patients were prospectively followed for 5 years. Those who were lost to follow-up were excluded from the study. Perioperative complications and recurrences were evaluated.
The mean follow-up period was 29 months. Mean operation time was 27.5 minutes. Forty one percent of the patients had contralateral patent processus vaginalis. Only one hernia recurred (0.19%). We had one case of contralateral metachronous hernia (0.21%) during follow-up period.
The long-term follow-up results of our study revealed that laparoscopic hernia sac transection and ligation can be a safe and effective alternative for conventional herniorraphy.
Minimally invasive techniques for pediatric inguinal hernia repair have been evolving in recent years. We applied the laparoscopic method to repair pediatric inguinal hernia using the techniques of sac transection and intra-corporeal ligation. Between November 2008 and August 2010, 67 pediatric patients (47 boys and 20 girls) with inguinal hernias were included in this study. Postoperative activities, pain, and complication were checked prospectively at regular follow-up. One patient presented with clinically bilateral hernia, and three patients had metachronous hernias. Thirty-two cases out of 63 patients with unilateral hernias had a patent processus vaginalis on the contralateral side. Mean operation time was 35±11.4 minutes for unilateral hernias and 43±11 minutes for bilateral hernias. There were no intra-operative complications. One patient had a small hematoma on the groin postoperatively, which subsided spontaneously in a week. Recurrence and metachronous hernia were not found at follow up. In summary, laparoscopic inguinal repair in children is safe, easy to perform and has an additional advantage of contralateral exploration. Further studies should include long term follow-up.
