Long-term absorbable versus non-absorbable suture in laparoscopic percutaneous extraperitoneal closure of internal ring for inguinal hernia in children

Abstract

AimTo compare the results of using long-term absorbable (LTAS) versus non-absorbable suture (NAS) in laparoscopic percutaneous extraperitoneal closure of internal ring (LPEC) for indirect inguinal hernia (IH) in children MethodsProspectively collected data from children undergoing LPEC for IH at our center were retrospectively reviewed to compare group A repaired with NAS (2.0 monofilament polypropylene or braided polytetrafluoroethilene) to group B repaired with LTAS 2.0 polydioxanone. Results481 patients with 499 IHs in group A were compared to 277 patients with 283 IHs in group B. There were no significant differences in terms of age, bodyweight and laterality of IH between the two groups. At a median follow up period of 30 months, the incidence of suture knot reaction (SKR) and hernia recurrence were 3.1% and 1.0% in group A vs. 0% and 6.4% in group B with p = 0.002 and p<0.001, respectively. Monofilament NAS was associated with a low rate of both recurrence and SKR. ConclusionsLPEC repair for pediatric IH using LTAS is associated with no SKR but a higher recurrence rate compared to NAS. Monofilament NAS such as Prolene could be a good choice in LPEC because of its low rate of both recurrence and SKR.
