AIMS: This study examines the intraperitoneal behavior of two cyanoacrylate tissue adhesives: Ifabond® and a new, non-marketed octyl cyanoacrylate adhesive (OCA) used for the intraperitoneal fixation of a laminar expanded polytetrafluoroethylene (ePTFE) mesh.
MATERIAL AND METHODS: In 36 New Zealand White rabbits, 3 × 3 cm (n = 24) or 1.5 × 3 cm (n = 12) fragments of ePTFE mesh (Preclude® , Gore, Flagstaff, USA) were fixed to the parietal peritoneum using OCA or Ifabond® . Peritoneal fluid was obtained at the time of implant and at 2 weeks postimplant for determination of the cytokines interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α). At 14 or 90 days postsurgery, the animals were euthanized and the meshes excised to assess host tissue incorporation, the macrophage response, apoptosis and fixation strength (T-peel tensiometry).
RESULTS: Peritoneal fluid IL-6 and TNF-α concentrations were similar in the OCA and Ifabond® groups. Both adhesives gave rise to adequate mesothelialization of the laminar ePTFE. Macrophage counts were similar for the two study groups, but a significantly increase in macrophage response was observed from 14 to 90 days for Ifabond® . At 90 days postimplant, apoptotic cell counts was lower for the implants fixed with OCA and a fixation strength was significantly lower for OCA.
CONCLUSIONS: Despite similar cytokine levels at 2 weeks and similar host tissue incorporation observed for the meshes fixed with the two adhesives, the use of Ifabond® gave rise to a greater apoptosis rate, although this adhesive provided a stronger fixation bond. © 2015 Wiley Periodicals, Inc.
