Incisional hernia surgery has witnessed an important progress over the last years, not only as far as the pathophysiological and etiopathogenetic aspects are concerned, but also from a technical point of view. Thanks to the recent findings on genetical disorders of the collagen, incisional hernia is today considered a true 'disease of the abdominal wall'. Surgeons need to be aware of all the different repairing techniques, in order to make an elective choice and to keep side effects and recidives under control. Today, on the basis of the most recent research on synthesis of collagen and collagenolysis, the treatment of the incisional hernia should not disregard the use of synthetic prostheses and of biomaterials, both in the routinal surgical practice and in the most complex clinical cases. Surgeons, surgical residents, and medical students will find this volume very useful in their daily practice.
