Will Quantifying Fascial Tension Change the Practice of Component Separations in Complex Abdominal Wall Reconstruction?

Miller and colleagues published their work on the quantification of anterior and posterior fascial release after posterior component separation (PCS) and transversus abdominis release (TAR) using a proprietary, sterilizable tensiometer on anesthetized patients with ventral hernia. To our knowledge, this is the largest study of its kind in our review. Their findings demonstrated that anterior fascial tension was most impacted by the retrorectus dissection. This step contributed −82% of the total change in anterior fascial tension, compared with −18% from the incision of the internal oblique posterior lamella and 0% from the TAR. Posterior fascial tension experienced the largest release from the posterior lamellar incision, followed by the TAR and retrorectus dissection , with percentage change in tension of −53%, −38%, and −3%, respectively.
