Hernia occurrence is on the rise. The most common approach to repair today is a hernioplasty repair using a surgical mesh for permanent reinforcement after repairing the hernia defect. Different fixation techniques using materials such as tacks, staples, sutures, or adhesives are utilized to provide initial fixation until tissue ingrowth occurs. Currently, regarding ventral hernia mesh repair operations there is inadequate amount of information available regarding the efficiency of a mesh repair using adhesives. Consequently, this study compares the interface strength between mesh and tissue when mesh is fixed with either of the two following techniques: a) adhesives or b) sutures. Lap shear test conducted on excised tissue specimens determined the fixation strength of the interface between tissue and mesh at 24 hours, 1 week, and 2 weeks post recovery. Uniaxial experiments were used to obtain nonlinear material properties of mesh and tissue. The material properties were then utilized toward building a computational model of the mechanical experiments.
