Final study results demonstrate for the first time efficacy of long-lasting absorbable biosynthetic mesh in challenging hernia repairs; has potential to end biologics era in hernia repair
FLAGSTAFF, ARIZ.--(Business Wire/Korea Newswire) January 5, 2016 -- W. L. Gore & Associates, Inc. (Gore) today announced final results of a long-term, prospective, multicenter study 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 and physicians interested in learning more about the study can view the paper here.
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 Tissue Reinforcement. Typically, in this type of patient population, the recurrence rate is as high as 30 percent with a biologic mesh. The investigators reported that no biosynthetic required complete removal due to infection.
“I think this study represents an important step forward in defining the most appropriate way to reconstruct complex abdominal wall defects,” said Dr. Rosen. “Bio A [GORE BIO-A Tissue Reinforcement] performed very well in this challenging group of patients and will provide a cost-effective alternative for reconstructive surgeons.”
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.
GORE BIO-A 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 favorable type I collagen.
“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,” said Ron Anderson, General Surgical Products Business Unit Leader. “By being both more cost-effective for hospitals and payors while also improving quality of life for patients, GORE BIO-A Tissue Reinforcement is truly advancing healthcare and the way we treat CVH.”
