[Technical principles of incisional hernia surgery].

Many publications are available on the best surgical techniques and treatment of incisional hernias with reports of experiences and randomized clinical studies at the two extremes of the evidence scale. The ultimate proof of the best operative technique has, however, not yet been achieved. In practically no other field of surgery are the variability and the resulting potential aims of surgery so great. The aim of surgery is to provide patients with the optimal recommendation out of a catalogue of possibilities from a holistic perspective. This article describes the surgical techniques using meshes for strengthening (in combination with an anatomical reconstruction) and for replacement of the abdominal wall (with bridging of the defect).
