Preoperative opioid use and incidence of surgical site infection after repair of ventral and incisional hernias.

Background: Preoperative opioid use is a risk factor for complications after some surgical procedures. The purpose of this study was to investigate the influence of preoperative opiates on outcomes after ventral hernia repair. Methods: With institutional review board approval, we conducted a retrospective review of consecutive ventral hernia repair cases during a 4-y period. Results: A striking 48% of the total 234 patients met criteria for preoperative opioid use. Preoperative characteristics and operative details were similar between patient groups (preoperative opioid use versus no preoperative opioid use). Median duration of hospital stay trended toward an increase for opioid users versus nonopioid users (P = .06). Return of bowel function was delayed in opioid users compared with nonopioid users (P = .018). Incidence of superficial surgical site infection was increased among patients who used opioids preoperatively (27% vs 8.3%; P <.001) and remained so after multivariable logistic regression, (adjusted odds ratio 2.9, 95% confidence interval 1.2-6.7; P = .013). Conclusion: Among patients undergoing ventral hernia repair, those with preoperative opioid use experienced an increased incidence of superficial surgical site infection compared with patients without preoperative opioid use. Further study is needed to understand the relationship between opioid use and surgical site infection after ventral hernia repair. (C) 2020 Elsevier Inc. All rights reserved.
