Biological meshes for abdominal hernia: Lack of evidence-based recommendations for clinical use

Our analysis provided an overview of 5 biological meshes currently available on the market. The different types of meshes showed a marked statistical variability in the clinical outcomes. Hence, nearly all comparisons between different meshes in the two clinical end-points did not reach statistical significance. One exception was represented by the finding that cross-linked meshes had a significantly lower recurrence rate at 12 months than non-cross-linked meshes.
