Abstract
Introduction
In inguinal hernia repair, mesh weight and pore size are used to describe the mesh characteristics. One meta-analysis of laparo-endoscopic inguinal hernia repairs identified 12 prospective randomized controlled trials (RCTs) with 2,909 patients who had all been treated with lightweight (≤ 50 g/m²) or heavyweight (> 70 g/m²) meshes. None of the 12 RCTs gave details of the pore size. There were more recurrences when using lightweight meshes, in particular in the case of medial defects without mesh fixation and/or large defects. In terms of pain, no significant differences were seen. This retrospective analysis of data from the Herniamed Registry now aims to analyze whether mesh pore size is related to the outcome in laparo-endoscopic inguinal repair.
Materials and methods
To analyze the association between mesh pore size and the outcome in laparo-endoscopic inguinal repair, it was necessary to select meshes with comparable properties. Polyester meshes and PTFE meshes had to be excluded and polypropylene and polyvinylidene fluoride meshes (PVDF) were included. 83,768 included patients were retrospectively analyzed. The meshes analyzed were eight small-pore and 13 large-pore meshes. Using a binary logistic regression model, it is possible to simultaneously analyze several factors being potentially associated with the outcome.
Results
Higher BMI, lower weight meshes, higher ASA score and medial EHS classification were associated with a higher risk of recurrence. It was not possible to find any significant association between pore size and recurrences at one-year follow-up. This also applied for pain on exertion and pain requiring treatment.
Conclusion
No association was identified between the pore size of the meshes used in laparo-endoscopic inguinal repair and the recurrence rate, pain on exertion rate or the rate of chronic pain requiring treatment at one-year follow-up.
