Summary
New study from Farr et al. into the effect of implanting polypropylene (PP) surgical mesh into patients. More evidence is needed to show the harmful effect to patients by implanting a foreign body into them, especially into the pelvic floor.
Content
- To the authors’ knowledge, this is the first study to quantify oxidative stress induced debris from PP surgical mesh.
- The findings of the data presented indicate that oxidative stress alone is a major factor in the production of PP particle debris.
- With previous studies having already raised concerns regarding the effect of nano-micron sized particles effect on human health, these findings emphasize the need for future studies to gain a deeper understanding of how macrophages and fibroblasts involved in the immune response, respond to this oxidative debris.
- Future studies should therefore consider these oxidative stress findings together with the application of mechanical distention through extending the test model to form a higher fidelity representation of the implantation environment.
- Particular attention should be given to mechanically induced changes to surface morphology and the mechanism of particle shedding.
- Lastly, the effect of oxidative stress is not expected to be limited to PP, consideration should also be given to including a wider range of test materials encompassing all those used within pelvic floor reconstruction.
