Laparoscopic Percutaneous Extraperitoneal Internal Ring Closure for Pediatric Inguinal Hernia: 1,142 Cases.

Purpose: The purpose of this study was to summarize the clinical experience of the laparoscopic percutaneous extraperitoneal closure of the internal ring using an epidural needle for the treatment of inguinal hernias. Methods: There were 1,142 children with an isolated inguinal hernia who participated in this study from January 2013 to May 2018. An epidural needle was used to treat the indirect inguinal hernia with laparoscopic assistance. Symptoms and signs were followed up at 1 week, 3 months, and every 1-2 years after the operation. Results: All 1,142 children underwent laparoscopic surgery successfully. All patients were discharged 1-2 days after the operation. During the hospitalization and follow-up, there were 21 patients with complications, including 6 cases of hernia recurrence, 7 cases of poor healing of the umbilical incision, 5 cases of suture granuloma and 3 cases of groin traction pain discomfort. None of the following complications occurred: abdominal wall vascular injury, deferent duct injury, umbilical hernia, iatrogenic cryptorchidism, testicular atrophy, hydrocele, or scrotal oedema. Conclusion: Laparoscopic percutaneous extraperitoneal closure of the internal ring using an epidural needle is a safe and feasible method for the treatment of inguinal hernias in children. This method has the advantages of less trauma, no scarring and a good cosmetic effect.
