The PS is just to control scaring, and maybe to assist with a finer/stronger suture pattern to prevent further hernias. Especially if the mesh is placed laparoscopiclly, there are satellite incisions for the camera and air tube. You don't want either of these secondary incisions to develop hernias.
There are different types of mesh in use with different strength, pore size, and resistance to adhesion. At least one mesh has been subject to a major recall in recent years. Some reading on types of mesh might be good.https://www.sciencedirect.com/science/article/pii/s1743919112000921
" ... four different material groups have become available for hernia repair and abdominal wall reconstruction: PP, PTFE, ePTFE and Polyester (POL). PP is a hydrophobic polymer of carbon atoms with alternating methyl moieties. This material is flexible, strong, easily cut, readily integrated by surrounding tissues and resists infection. The monofilament nature provides large pores facilitating fibrovascular ingrowth, infection resistance and improved compliance. PP remains the most popular material in mesh hernia repair"
"...Before selecting a mesh for an individual patient, a surgeon must take into account patient characteristics (such as age, defect size, obesity, underlying disease process, etc.), and mesh properties to determine the appropriate treatment. The mechanical compatibility between the hernia meshes and the abdominal wall layers plays an important role in avoiding postoperative complications and recurrences. "
Talking with the surgeons on mesh choices, and finding out why one mesh was recently recalled - all this would be due diligence.
"Many complications related to hernia repair with surgical mesh that have been reported to the FDA have been associated with recalled mesh products that are no longer on the market. Pain, infection, recurrence, adhesion, obstruction, and perforation are the most common complications associated with recalled mesh."
