Abstract
Background: We evaluated efficacy and associated adhesion formation of an innovative mesh fixation device versus the helical tack device and analyzed two implantation techniques. Methods: Six purpose-bred female hounds were evaluated in this 90-day survival study. Six 4-cm round patches of 1-mm thick DualMesh were fixed to the abdominal wall with either 10 Pro-Tack or 10 Salute constructs in each patch. Zero to 4 additional patches were implanted with only Salute constructs. Results: Adhesion severity scores were significantly higher for middle left abdominal wall sites versus lower right and upper left sites. The adhesion dissection score was higher for group T (Pro-Tack) versus group S (Salute). Conclusion: No significant effects occurred with adhesion extent scores, but group T developed denser adhesions. The second analysis determined that no significant differences existed relevant to secondary Salute placement, although the total score approached significance (p < 0.09). Salute equipment was easier to handle and allowed repositioning of the patch during operation.
