Abdominal wall reconstruction has become a frequently used term to describe hernia repairs that try to recreate the abdominal wall and restore function and structure. Although there has been no universally agreed-upon definition of a functional abdominal wall, many surgeons believe this involves the closure of the fascia at the midline, often with reinforcement using mesh prosthetics.
The integrity of the abdominal wall is vital as it serves to protect the internal organs, supports the spine and helps maintain an upright posture. Also, the abdominal wall aids in the performance of several bodily functions requiring the generation of Valsalva such as urination, coughing, and defecation. There are also data suggesting an absence of an intact abdominal wall can lead to a sensation of insatiety, possibly contributing to weight gain.
