**2. Incisional hernia classification**

Developing a good classification for incisional hernias is much more difficult than for groin hernias or for primary abdominal wall hernias because of their great diversity. The classification as established and published by the consensus meeting of the European Hernia Society held in Ghent, Belgium, 2008, (Tab 1.) comprises a division of subgroups for incisional hernia, including localization, width, and length of the hernia [9]. The use of the classification of the European Hernia Society is nowadays recommended. The analysis of subgroups may define patients with high risk for recurrences and may lead to specific treatment options. This classification is applicable in laparoscopic and open incisional hernia repair.
