Core Tip

Core tip: Hernia repair is one of the most frequently performed surgical interventions that use mesh implants. This article evaluates crucial mesh parameters to facilitate selection of the most appropriate mesh implant based on raw material, mesh composition, and structural and mechanical parameters. The structural parameters of the mesh, especially the porosity, are the most important predictors of the biocompatibility performance of synthetic meshes. Monofilament large-pore meshes exhibit less inflammatory infiltrate, connective tissue and scar bridging, which allows increased soft tissue ingrowth. The value of mesh classification based on the mesh weight seems to be overestimated. Other properties, such as the isotropy, elasticity and tensile strength, are crucial parameters for predicting the performance of meshes after implantation.
