How safe are permanent sutures? Hernia repaired 2 wks ago with Ventralex mesh. Want to get it removed and sutured. (photo)

ISince the surgery I have researched/discovered how dangerous mesh is, long and short term. My surgeon has told me that he will take the mesh out if I want and repair with dissolvable sutures, but the hernia will likely come back. After speaking to a Dr that specialises in non-mesh repairs he said that I definitely need it repaired with permanent sutures (which also contain polypropylene) is this true, and if so how safe is it to have permanent sutures in the body? Has testing been done on this?
