Physiomesh made by Ethicon is used primarily in hernia repair surgeries to support weakened tissue and to prevent recurring hernias. On May 25, 2016, Ethicon issued an urgent field safety notice announcing that it was withdrawing all of its products made with Physiomesh Flexible Composite Mesh. The withdrawal came after two studies showed a higher than average hernia recurrence and reoperation rates. Physiomesh is made with the synthetic material polypropylene, which has been known to erode surrounding tissue and is not fit for human implantation. Therefore, Ethicon has instructed doctors to stop using Physiomesh for hernia repair surgeries. Physiomesh can cause complications such as additional surgeries to treat hernia recurrence, additional surgeries to treat a mesh-related failure or injury, adhesions, bacterial infections, mesh migration, obstructions, pain, and swelling.
