Single-Site Laparoscopic Percutaneous Extraperitoneal Closure of the Internal Ring Using an Epidural Needle for Children with Inguinal Hernia.

ABSTRACT

BACKGROUND This study evaluated the safety and effectiveness of single-site laparoscopic percutaneous extraperitoneal closure of the internal ring using an epidural needle for children with inguinal hernia. MATERIAL AND METHODS We retrospectively analyzed clinical data of 542 children with inguinal hernia who underwent single-site laparoscopic percutaneous extraperitoneal closure of the internal ring using an epidural needle at our hospital from June 2014 to June 2017. RESULTS All patients successfully underwent surgery and none were converted to conventional surgery. Abdominal vascular injury, vasectomy injury, testicular vascular injury, umbilical hernia, iatrogenic cryptorchidism, testicular atrophy, hydrocele, hernia recurrence, and scrotal edema were not reported during the perioperative period. A follow-up of these patients was performed for 12-24 months. During the follow-up period, umbilical hernia, iatrogenic cryptorchidism, testicular atrophy, and hydrocele were not noted, but 3 cases of hernia recurrence were found. CONCLUSIONS The single-site laparoscopic percutaneous extraperitoneal closure of the internal ring using an epidural needle for children with inguinal hernia is safe and effective, and this procedure has the advantages of minimal trauma, no scarring, and good cosmetic effect.
