Toxic Hernia Mesh Plastic
Some studies and lawsuits say one of the problems with hernia mesh is it is made of polypropylene, a plastic that may be toxic in the body. Though polyethylene is supposed to be safe, according to one Material Data Safety Sheet from the chemical company LyondellBasell, polypropylene is not safe for "applications involving permanent implantation into the body."
Like hernia mesh, transvaginal mesh is also made of polypropylene. Pelvic surgical mesh manufacturers face nearly 100,000 lawsuits for filed by women who say the mesh caused severe and permanent damage requiring multiple surgeries to remove mesh.
As more surgeons practice laparoscopic hernia repair with mesh, more mesh may touch organs in the bowel. The laparoscopic intraperitoneal onlay mesh (IPOM) technique is popular with coated meshes. It places mesh inside the abdominal cavity directly against the intestines. Mesh makers began manufacturing coated mesh like C-QUR and Physiomesh to prevent polypropylene from directly touching organs.
But researchers noticed problems with migration, adhesions and inflammatory responses to these coatings.
During Donna Cisson's 2013 transvaginal mesh trial against C.R. Bard, emails surfaced revealing the company's Davol hernia mesh unit used plastic not suitable for human implantation. According to a Bloomberg report, the plastic's manufacturer — chemical company Chevron Phillips — told Bard the polypropylene resin should not be permanently implanted in people. Davol told manufacturers to continue making the mesh from the Chevron Phillips plastic and agreed to cover any legal costs or damages, according to the emails.
