Abstract

Abstract : Background: To help prevent complications after incisional ventral hernia repair, traditional teaching has recommended using closed suction drains. However, some studies suggest that there is an increased infection risk with use of surgical drains, and it is uncertain whether use of extended postoperative prophylactic antibiotics while drains remain in place helps prevent surgical-site infections. Evidence guiding surgeons' clinical practice regarding antibiotic use following hernia repair is lacking. Methods: The authors sought to determine whether the use of extended postoperative antibiotic prophylaxis beyond standard Surgical Care Improvement Project guidelines with closed-suction surgical drain placement in incisional ventral hernia repair reduces the incidence of postoperative surgical-site infections. A retrospective review of 234 patients who underwent an incisional ventral hernia repair from 2003 to 2013 at a single institution was performed. Demographic, preoperative, operative, and postoperative data were collected and analyzed. Results: Extended postoperative prophylactic antibiotics significantly reduce the incidence of postoperative surgical-site infections (OR, 0.31; p < 0.01). The odds ratio, when stratified by Ventral Hernia Working Group Scale, was 0.63, 0.25, 0.30, and 0.13 ( p < 0.001 by the Mantel-Haenszel combined test) for grades 1, 2, 3, and 4, respectively, but was not statistically significant for differences between hernia grades. However, as the hernia grade increased, the odds ratio tended to decrease, suggesting that extended prophylactic antibiotics may be more effective at decreasing the incidence of surgical-site infections at higher grades. Conclusion: Extended antibiotic prophylaxis reduces surgical site infection risk following complex ventral hernia repairs, and should be considered in all cases.
