  • Title: A comparison of polypropylene mesh, expanded polytetrafluoroethylene patch and polyglycolic acid mesh for the repair of experimental abdominal wall defects.
    Author: Law NW.
    Journal: Acta Chir Scand; 1990; 156(11-12):759-62. PubMed ID: 1963726.
    Abstract:
    Abdominal wall defects created in Sprague-Dawley rats were repaired with either polypropylene mesh (PPM), expanded polytetrafluoroethylene patch (PTFE) or polyglycolic acid mesh (PGA). Tensiometric studies of abdominal wall strength showed that PPM and PTFE provided a strong repair, but that the fibrous response induced by PGA was insufficient to produce a strong support for abdominal wall reconstruction. The size of the overlap at the interface between the abdominal wall fascia and prosthetic material has a greater effect on wound strength with expanded PTFE than with PPM. This is because of the different pattern of collagen infiltration into each material.
