Is the dissection of the abdominal wall still necessary in the treatment of W3 hernias?

Large incisional hernias are a permanent problem for surgeons in a growing number of operations. For the treatment of complex hernias, there are no internationally accepted evidence-based recommendations regarding the restoration of abdominal wall integrity. In this paper, we are reviewing the development of different component separations (CS) and other techniques used in treating such conditions. A literature review was carried out to describe some important techniques to treat giant hernias. After a detailed description of the CS and its important modifications, we are describing and discussing the relatively new fascial traction technique with its modification. With these reviews of the mentioned studies, we are questioning the extent to which the CS is still indicated in treating giant hernias and point out the importance of further comparison studies evaluating different techniques.
