Abstract
Ventral hernia is an abnormal protrusion of the abdominal contents through a defect in the anterior abdominal wall (Parker et al., 2021). Ventral hernias include incisional, epigastric, paraumbilical, umbilical, spigelian, and traumatic hernias. Incisional hernias are the largest and most difficult group to treat among all ventral hernias (Ahmed and Beckingham, 2004). Ventral hernia repairs represent one of the commonest performed surgical techniques including more than 348,000 repairs performed in the USA every year (Bower and Roth, 2013). Large ventral hernias are hernias with defect larger than 10 cm with loss of domain and hernia volume more than 30% of abdominal volume (Passot et al., 2016). They mostly cannot be closed primarily and considered as challenging surgical procedures (de Vries Reilingh et al., 2007). Albanese (1966) described the concept of relaxing incisions with muscle mobilization to close large defects to avoid abdominal compartment syndrome. Ramirez et al. (1990) popularized anterior components separation technique innovated by Young (1961) in epigastric incisional hernia repair to bridge fascial gap without use of mesh. However, this technique required large skin flaps mobilization which were associated with high morbidities (Krpata et al., 2012).
