Abstract： Objective To evaluate the feasibility of single-port laparoscopic percutaneous extraperitoneal closure for pediatric inguinal hernia.Methods Between June 2013 and June 2015,a total of 312 patients with inguinal hernia underwent single-port laparoscopic percutaneous extraperitoneal closure.Under laparoscopic visualization,a modified hernia needle was inserted at the corresponding point of internal ring.Hernia defect was obliterated extraperitoneally by a nonabsorbable suture entering into abdomen on one side and exiting on the opposite side in an identical subcutaneous path around internal ring.Results A total of 442 inguinal repairs were successfully performed.The sides were unilateral (n =43) and bilateral (n =144).And 104 patients of unilateral indirect inguinal hernia were confirmed to be bilateral.There was no postoperative onset of bleeding,pain or early recurrence.During a mean follow-up period of 16.7 (5-29) months,there was no recurrence,visible scar on abdominal wall or foreign body feeling of inguinal site.Conclusions Singleport laparoscopic percutaneous extraperitoneal closure is both safe and efficacious for pediatric inguinal hernia It may be conveniently performed with high parental satisfaction,minimal scarring and excellent cosmetic outcomes.
