    Abstract:
    BACKGROUND: Ventral hernia formation is a frequent and increasingly difficult problem. Nonmidline hernias, parastomal hernias, hernias near bony landmarks, and recurrent ventral hernias (especially after anterior component separation) present particular challenges. Typical reconstructive techniques may struggle to reestablish abdominal domain and to create a lasting repair. Posterior component separation with transversus abdominis release is a novel technique that offers a durable solution to a variety of complex ventral hernias. METHODS: The posterior rectus sheath is incised and the retrorectus plane is developed. In a modification of the Rives-Stoppa technique, the transversus abdominis is released medial to the linea semilunaris to expose a broad plane that extends from the central tendon of the diaphragm superiorly, to the space of Retzius inferiorly, and laterally to the retroperitoneum. This preserves the neurovascular bundles innervating the medial abdominal wall. Mesh is placed in a sublay fashion above the posterior layer. In an overwhelming majority of patients, the linea alba is reconstructed, creating a functional abdominal wall with wide mesh reinforcement. RESULTS: The technique is reliable and durable, with a 5 percent recurrence rate at 2 years. Although wound complications occur with a frequency similar to that of other techniques, they tend to be less severe, rarely requiring operative débridement. The technique is applicable to a broad range of hernias, including midline, parastomal, flank, subcostal, and recurrent hernias after prior component separations. CONCLUSION: Posterior component separation with transversus abdominis release is a versatile, easy-to-learn technique of hernia repair that offers a reliable, durable solution to complex abdominal wall reconstruction.
