Background: Abdominal procedures, whether open or laparoscopic are often complicated with an incisional abdominal hernia (IH). Approximately 15% - 20 % of all laparotomies and 1% to 5% of all laparoscopic surgeries are complicated by IHs. IH is a really bad situation for doctors and patients. Dissatisfaction, long-term malfunction, and limitations of activities and unsatisfying cosmetic appearance are just a few of the side effects that patients endure as a result of IH. For doctors; it is a challenging surgical issue associated with multiple risk factors, unclear etiology and different pathological changes, affecting different patients. Management of such a variable surgical issue necessitates a good understanding of the anatomical and physiological features of the abdominal wall by the hernia surgeon beside a wide armamentarium of surgical options to deal with complex variants to repair and restore abdominal wall integrity and function, many procedures have been utilized to repair IH and to restore abdominal wall integrity. Objective: To review the feasibility and safety of the abdominal wall component release with contemporary onlay mesh fixation procedure in the treatment of incisional abdominal hernias. Conclusion: Large incisional hernias that are difficult to close in the midline might benefit from the component separation approach. Repair of incisional hernias by abdominal wall component separation with contemporary onlay mesh fixation results in favorable outcomes and lower recurrence rates. It gives a more durable abdominal wall repair, a more physiological repair in cases of loss of domain, an affordable financial outlay, and a low incidence of complications.
