  1. Forum on complex and complexity in abdominal wall hernia repair



The abdominal wall can be considered comprised of two compartments: an anterior and a posterior compartment. The anterior compartment includes the anterior rectus sheath and the rectus muscle. The posterior compartment comprises the posterior rectus sheath, the transversalis fascia, and the peritoneum. When a large defect in the anterior compartment has to be corrected, for example, a rectus diastasis or large incisional hernia, an action on the anterior compartment is necessary; therefore, an anterior component separation has to be considered. If a loss of substance is present in the posterior compartment, a trasversus abdominis release should be accomplished.


We propose an original anterior compartment mobilisation, by a posterior approach. Dissection of the posterior rectus sheet proceeds until the linea semilunaris is reached. Incision of the anterior rectus sheath permits a mobilisation of the anterior compartment by a posterior approach. A mesh is placed in a sublay position. If the abdominal wall presents a loss of substance of the posterior compartment, a transversus abdominis release (TAR) can be performed in the same time.


No hernia recurrences, no wound infection, and no mesh infection have been reported.


The anterior compartment mobilization permits mobilization towards the midline of rectus muscle and restoration of anterior compartment, with low morbidity rate; it can be easily associated to a large sublay mesh placement, it allows the preservation of the neurovascular bundles and rectus muscle trophism, and it can be associated with a concomitant TAR procedure for the restoration of the PC, if necessary.
