Abstract

Insights

Xenograft biologic mesh complications are frequently reported to the FDA, especially with cross-linked meshes. Further research is needed to understand mesh properties and infection outcomes in abdominal wall reconstruction.

Area of Science:

  • Biomaterials Science
  • Surgical Innovation
  • Medical Device Safety

Background:

  • Limited research exists on xenograft biologic mesh performance during infection.
  • Xenograft meshes are widely used in abdominal wall reconstruction, incurring significant costs.
  • Understanding mesh behavior in infected environments is crucial for patient safety.

Purpose of the Study:

  • To analyze adverse events (AEs) reported to the FDA concerning xenograft biologic meshes.
  • To identify common complications and contributing factors for mesh failure.
  • To evaluate the safety and efficacy of xenograft meshes in abdominal wall reconstruction.

Main Methods:

  • Retrospective review of FDA database for xenograft mesh adverse events.
  • Analysis of meshes used in abdominal wall reconstruction between 1997 and 2008.
  • Categorization of adverse events and associated mesh types.

Main Results:

  • 150 adverse events were identified, with Permacol and Collamend accounting for 75%.
  • Primary complications included mechanical failure (42%), disintegration (32%), and poor integration (13%).
  • 80% of cases involved infection, and nearly 90% required reoperation.

Conclusions:

  • Xenograft biologic meshes, particularly cross-linked types, are associated with major complications reported to the FDA.
  • The relationship between mesh properties and infection outcomes remains poorly understood.
  • A careful evaluation of these medical devices is warranted based on FDA adverse event data.
