A Current Review of Synthetic Meshes in Abdominal Wall Reconstruction

The use of mesh materials for reinforcement of the abdominal wall has revolutionized the approaches to hernia repair. Whether it's a permanent, synthetic mesh, a biologically derived collagen graft, or a synthetic, bioresorbable construct, data demonstrate improved outcomes with respect to recurrence with their use. Numerous advances and development of component separation techniques of the abdominal wall musculature have provided surgeons the ability to close large fascial defects and reestablish the linea alba for midline hernias. Augmentation of the these repairs with a mesh helps to offset the tension on the fascial closure and provide biomechanical strength to the native tissue. However, the use of mesh materials as either permanent or temporary scaffolds is not without potential complications. Abdominal wall surgeons must have knowledge of the mesh composition and structure in an effort to mitigate these concerns. This chapter will review the polymers and characteristics of the currently available synthetic meshes for abdominal wall reconstruction in an effort to provide guidance to surgeons.
