Prospective study of single-stage repair of contaminated hernias with the novel use of calcium sulphate antibiotic beads in conjunction with biologic porcine submucosa tissue graft.

SUMMARY: In single-stage hernia repair in the setting of contaminated fields there is a high rate of infection following mesh repair. New strategies to decrease infection in this challenging patient population are needed. Stimulan calcium sulfate antibiotic beads (CSAB) are a biodegradable material that deliver high concentrations of antibiotics locally to a site of insertion. Their use in the prevention of infection has not been described in hernia graft implantation. Here we describe our use of CSAB in a series of 11 patients with modified Ventral Hernia Working Group class III and Centers for Disease Control and Prevention class II-IV wounds undergoing single-stage incisional ventral hernia repair. We found that implantation of CSAB in single-stage hernia repair in the setting of contaminated fields was feasible with low systemic antibiotic levels. Further research should be undertaken to investigate the efficacy of this novel tool in hernia repair.
