Laparoscopic percutaneous extraperitoneal closure with peritoneum reinforcement repair for pediatric inguinal hernia: a single-center experience with over 2,000 patients.

Abstract

BackgroundInguinal hernia is one of the common diseases in infants and children that requires operative treatment. Laparoscopic inguinal hernia repair in children has become an alternative to the open procedure. Laparoscopic percutaneous extraperitoneal closure with peritoneum reinforcement (LPECPR) is a safe and effective approach for pediatric inguinal hernia, and has a lower recurrence. This is a retrospective study to present our experience with children who underwent LPECPR.MethodsA total of 2,018 patients with inguinal hernia who underwent LPECPR in our hospital from July, 2011 to December, 2020 were reviewed. The surgical technique is modified on the basis of laparoscopic percutaneous extraperitoneal closure (LPEC) to close extraperitoneally by circuit suturing twice around the internal inguinal ring.ResultsAll cases were completed LPECPR without conversion. There were no intraoperative complications. A total of 2,018 patients’ laparoscopic procedures were achieved. The mean operative time was 14 and 20 min for unilateral and bilateral operations, respectively. Follow-up to date is 13.4 months (6–36 months), there were no postoperative complications, such as knot reactions, hydrocele formation, testicular atrophy or pain, except 3 recurrences (3/2,018, 0.15%).ConclusionsThis modified LPECPR technique can acquire lower recurrence rate for repair pediatric inguinal hernia. The midterm safety and efficacy of LPECPR are proven and it can be a routine procedure.
