Insights
For pediatric indirect inguinal hernias, non-absorbable sutures (NAS) in laparoscopic percutaneous extraperitoneal closure (LPEC) showed fewer recurrences than long-term absorbable sutures (LTAS), with minimal suture knot reaction.
Area of Science:
- Pediatric surgery
- Surgical innovation
- Hernia repair techniques
Background:
- Indirect inguinal hernia (IH) is common in children.
- Laparoscopic percutaneous extraperitoneal closure (LPEC) is a minimally invasive approach for IH repair.
- Suture material choice may impact LPEC outcomes.
Purpose of the Study:
- To compare the efficacy and safety of long-term absorbable sutures (LTAS) versus non-absorbable sutures (NAS) in pediatric LPEC for IH.
- To evaluate recurrence rates and suture-related complications.
Main Methods:
- Retrospective review of prospectively collected data from children undergoing LPEC for IH.
- Comparison of two groups: Group A (NAS - polypropylene or polytetrafluoroethilene) and Group B (LTAS - polydioxanone).
- Analysis of outcomes including suture knot reaction (SKR) and hernia recurrence.
Main Results:
- 481 patients (499 IHs) in Group A vs. 277 patients (283 IHs) in Group B.
- Median follow-up of 30 months.
- Group A (NAS) had 3.1% SKR and 1.0% recurrence.
- Group B (LTAS) had 0% SKR and 6.4% recurrence (p < 0.001 for both).
- Monofilament NAS demonstrated low recurrence and SKR rates.
Conclusions:
- LPEC repair of pediatric IH with LTAS is linked to a higher recurrence rate compared to NAS.
- NAS, particularly monofilament types like Prolene, may be preferable in LPEC due to low recurrence and SKR rates.
- No suture knot reaction was observed with LTAS, but recurrence was higher.
Aim:
To 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 METHODS: Prospectively 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.
Results:
481 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.
Conclusions:
LPEC 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.
