Background: Wide or recurrent midline abdominal wall defects are usually challenging surgical problem. Midline abdominal wall dehiscence resulting as a complicated wound healing after laparotomy is the most challenging. Friability of the wound edges, concomitant infections and the debilitated general condition of the patient due to long hospitalization make the healing potential low. Ideal repair should utilize native tissue and should restore the dynamic properties of the abdominal wall. 

Patient and Methods: Components separation technique (CST) was used to reconstruct abdominal wall defects in 20 patients (8 males and 12 females) over a period of 10 years. 

Results and Conclusions: The technique of components separation is very reliable and easy to learn and to do. It is also very effective in repairing midline abdominal wall defects of various etiologies. It provides well-vascularized native tissues for the reconstruction and it restores the dynamic integrity of the abdominal wall. It is particularly useful for the repair of midline post-laparotomy wound dehiscence.
