Incisional hernias can occur at the site of surgical incisions in the abdominal wall. They are due to the tearing of the closing suture of the primary operation (laparotomy) and to healing problems of tissues, linked to the patient’s medical condition, such as obesity, cough or diabetes.

The size of incisional hernias is very variable, from small holes measuring a few centimeters, to large defects of ten and more centimeters, with exteriorization of a large part of intestine.

Large incisional hernias constitute a serious condition, with a high risk of complications. In most cases a patch is necessary. It can be placed by laparoscopy in small and midsized hernias, but requires open surgery in large hernias.
