Optilene® Mesh Elastic and Ultrapro® Mesh will be used for incisional hernia repair. The primary objective of this clinical study is to demonstrate that Optilene® Mesh Elastic is superior to Ultrapro® Mesh in incisional hernia repair in matter of the physical function score from the SF-36 questionnaire 21 days after mesh insertion. Secondary objectives include the patient's daily activity, the rating of patients pain and the wound assessment determined on several occasions during the six months observation time.

Arms Assigned Interventions
Experimental: A
Optilene® Mesh Elastic
Device: Mesh Implantation
An elective incisional Hernia repair is performed by using Optilene® Mesh Elastic, a lightweight and large pore mesh, knitted from monofilament polypropylene. Due to the multidirectional elasticity the mesh is able to adapt to all movements taking place in the abdominal wall.
Other Name: Optilene® Mesh Elastic
Active Comparator: B
Ultrapro® Mesh
Device: Mesh Implantation
Ultrapro® Mesh is a knitted, partly absorbable, lightweight mesh, consisting of equal parts of nonabsorbable polypropylene and absorbable polyglecaprone (Monocryl®). Polyglecaprone is fully absorbed in the body by hydrolysis. The addition of polyglecapron filament is only intended to reinforce the mesh to allow a convenient intraoperative handling and mesh placement, without additional function. Ultrapro® is an elastic mesh having enlarged elasticity cross to the blue strips.
Other Name: Ultrapro® Mesh
