Complex ventral hernia repair using components separation with or without synthetic mesh: a cost-utility analysis.

Author information

  • 1Lebanon, N.H. From the Dartmouth Hitchcock Medical Center.



Components separation provides a useful option among closure choices for complex ventral hernia repairs. The use of synthetic mesh in addition to performing a components separation is controversial. The authors' goal was to perform the first cost-utility analysis on the use of synthetic mesh in addition to performing components separation when performing a complex ventral hernia repair in a noncontaminated field.


A comprehensive literature review was conducted to identify published complication and recurrence rates for ventral hernia repairs (Ventral Hernia Workgroup I and II) requiring components separation with or without synthetic mesh. The probabilities of the most common complications were combined with Medicare Current Procedural Terminology reimbursement codes, Diagnosis-Related Group reimbursement codes, and expert utility estimates to fit into a decision model to evaluate the cost-effectiveness of components separation with and without synthetic mesh in reconstructing ventral hernias.


At average retail costs, the decision model revealed a cost increase of $541.69 and a 0.0357 increase in quality-adjusted life-years when using synthetic mesh, yielding a cost-effective incremental cost-utility ratio of $15,173.39 per quality-adjusted life-year. Univariate sensitivity analysis revealed that synthetic mesh is cost-effective when it costs less than $2049.97.


The addition of synthetic mesh when performing components separation in repairing complex ventral hernias is cost-effective when using average retail prices. Physicians and hospitals should use synthetic mesh in patients with noncontaminated wounds.
