A Comparative Study of Repair of Complex Ventral Hernias with Double Mesh Repair (Sandwich Technique) and Single Mesh Repair in Adult Patients Admitted in General Surgical Wards

Ventral hernia is the herniation of a viscus or a part viscus through a defect in the anterior abdominal wall. It is a common condition encountered by surgeons in elective as well as emergency situations. Complex ventral hernias (CVH) include hernias with large defects (greater than10cm), multiple orifices and recurrent anterior abdominal wall hernia, mainly along the midline incision. The surgical treatment of large midline ventral hernias remains a challenge. Considering different causes of ventral hernias, wide differences in defect sizes, locations and associated medical comorbidities of every patient, it is less likely that a single approach to various ventral hernia repairs will ever be identified.
