Prosthetic Materials for Hernia Repair: Polyester
In addition to polypropylene and PTFE, polyester is a widely used synthetic for mesh repair of hernias. Polyester is somewhat easier to handle than polypropylene and PTFE as it sticks less to tissue and is softer. It is hydrophilic and produces less scar-tissue contraction than heavier materials.
Polyester performs well in a contaminated environment, although material that does not incorporate is usually removed. Granulation tissue will form through the pores even when exposed.
Polyester meshes are not typically used in inguinal hernia repair. They are occasionally used in ventral hernia repair as described below
Parietex – manufactured by Sofradim Corporation, composite mesh with polyester on one side and a combination of polyethylene glycol, glycerol, and oxidized collagen on the other side.
