Reducing the incidence of surgical site infection after ventral hernia repair: Outcomes from the RINSE randomized control trial.

Abstract

<h4>Background</h4>The clinical and financial impact of surgical site infection after ventral hernia repair is significant. Here we investigate the impact of dual antibiotic irrigation on SSI after VHR.<h4>Methods</h4>This was a multicenter, prospective randomized control trial of open retromuscular VHR with mesh. Patients were randomized to gentamicin ​+ ​clindamycin (G ​+ ​C) (n ​= ​125) vs saline (n ​= ​125) irrigation at time of mesh placement. Primary outcome was 30-day SSI.<h4>Results</h4>No significant difference was seen in SSI between control and antibiotic irrigation (9.91 vs 9.09 ​%; p ​= ​0.836). No differences were seen in secondary outcomes: SSO (11.71 vs 13.64 ​%; p ​= ​0.667); 90-day SSO (11.1 vs 13.9 ​%; p ​= ​0.603); 90-day SSI (6.9 vs 3.8 ​%; p ​= ​0.389); SSIPI (7.21 vs 7.27 ​%, p ​= ​0.985); SSOPI (3.6 vs 3.64 ​%; p ​= ​0.990); 30-day readmission (9.91 vs 6.36 ​%; p ​= ​0.335); reoperation (5.41 vs 0.91 ​%; p ​= ​0.056).<h4>Conclusion</h4>Dual antibiotic irrigation with G ​+ ​C did not reduce the risk of surgical site infection during open retromuscular ventral hernia repair.
