The use of a synthetic mesh to repair hernias, which is standard in most countries and widely accepted as better than primary suture repair.
The tensile strength required in mesh material is less than originally presumed and light-weight meshes are thought to be superior due to their increased flexibility and reduction in discomfort. Materials such as ePTFE have a low adhesion risk but a high risk of infection. In contrast, polypropylene meshes are durable and have a low infection risk, but little flexibility and a high risk of adhesion.
