[Mechanical value of prostheses and fixation with staples in repair of abdominal eventrations]

From an experimental study on fresh corpses, using a system which allows reproductible measures, we evaluated the physical strain to which prosthetic meshes are subjected during the initial phase of repair of abdominal eventrations treated by mesh. We also studied the various systems of staple fixation. The adhesivity or resistance-to-tear of the mesh is minimally dependent on the texture of the plaque; additionall, we also demonstrated the role of the size of the mesh. Stapling may compensate for the lack in size and increase the resistance-to-slip with larger values for radial stapling as compared to tangential stapling. Other fields of applications are possible. The use of glue or absorbable staples is considered.
