The necessary of closure of internal ring for cryptorchidism complicated with ipsilateral indirect inguinal hernia during laparoscopic surgery

Abstract

Objective To explore the necessary of closure of the internal ring for cryptorchidism complicated with ipsilateral indirect inguinal hernia. Methods Clinical data of 50 children with cryptorchidism complicated with ipsilateral indirect henia from June 2009 to May 2016 were analyzed in this study. All the cases underwent laparoscopic orchiopexy. All testes after complete mobilization were pulled down into the scrotum through the inguinal canal. No suture was applied to close the internal ring. The operative duration, profile of testicular descending and complication were assessed. Results Patent processus vaginalis was found in all 50 cases. There were 39 cases with inguinal canal cryptorchidism, 11 cases with intra-abdominal cryptorchidism. The mean operative time was 72 minutes. Primary orchidopexy was performed in all cases. The median follow up of all cases was 3 years (9 months to 6.5 years). There were 3 cases of testicular retraction to the top of the scrotum. No case was found recurrence of a hernia in ultrasound examination. Conclusion Laparoscopic orchidopexy is a safe and effective approach for children with cryptorchidism complicated with ispilateral indirect hernia. The closure of internal ring may not be necessary.
