Two important parameters in abdominal wall repair

Intra-abdominal Pressure (AP)

AP has been considered responsible for adverse effects in trauma and other abdominal catastrophes as well as in recurrence of hernias.5

Reports indicate that depending patient type and activity, the intra-abdominal pressure can be up to 250 mmHg.5

Range of maximum pressures generated for each maneuver in Cobb’s study.5

The ideal mesh

Meshes long term tolerance depends on their physical and mechanical properties.

When in contact with viscera, the meshes should be protected by a continous smooth barrier to minimize visceral adhesions.

Smooth and continous resorbable barriers outperform hydrophobic permanent barriers in preclinical models.
