W. L. Gore & Associates, Inc. has announced the final results of a long-term, prospective, multicenter study1 evaluating the use of GORE BIO-A Tissue Reinforcement, a biosynthetic mesh, in complex ventral hernia (CVH) repair in patients with contaminated wounds.

Results of the study led by lead investigator Michael Rosen, MD, Cleveland Clinic, was accepted for publication in the Annals of Surgery.

Patients scheduled to undergo CVH repair often have a poor quality of life preoperatively because of a gastrointestinal fistula, mesh infection, or non-healing abdominal wound. With more than 100 patients enrolled, these study results showed improved quality of life and intact hernia repairs in 83 percent of patients when using GORE BIO-A issue reinforcement. Typically, in this type of patient population, the recurrence rate is as high as 30 percent2 with a biologic mesh. The investigators reported that no biosynthetic required complete removal due to infection, according to a press release.

GORE BIO-A Tissue Reinforcement, as a biosynthetic mesh, also provides cost savings over a biologic mesh. Biologic mesh is often more expensive than biosynthetic mesh due to the complexity of harvesting tissue from cadavers or animal sources, as well as the subsequent processing and storage requirements to avoid the risks of viral contamination.

The Tissue Reinforcement is a uniquely designed web of biocompatible synthetic polymers that is gradually absorbed by the body, while its 3D matrix of open, highly interconnected pores facilitates tissue generation and healing. As a biosynthetic tissue scaffold, it is not derived from human or animal tissue but engineered for uniformity, consistency, and versatility. Clinical evidence demonstrates that the scaffold is replaced with favourable type I collagen.

Ron Anderson, general surgical products business unit leader said, “This study demonstrates for the first time something we have believed all along: a biosynthetic mesh offers specific advantages when compared with a biologic mesh. By being both more cost-effective for hospitals, while also improving quality of life for patients, GORE BIO-A Tissue Reinforcement is truly advancing healthcare and the way we treat CVH.” (GK)
