“Delayed-Immediate” Hernia Repairs in Infected Wounds: Clinical and Economic Outcomes

Abstract

Background Wound class in hernia repairs impacts surgical technique and outcomes. Hernia recurrence and complications are high when dirty wounds are treated in one stage. We hypothesize patients who undergo intentionally staged repairs are less likely to have adverse outcomes and associated costs. Methods Patients were identified by retrospective chart review. Patient characteristics and outcome variables were collected. An economic analysis of cost variables was performed using medical records and published meta-analyses. Results There were 8 patients in the staged repairs group and 10 patients in the control group. Length of stay was 14.9 days (±8.8), and 8.7 days (±6.4), respectively. Rate of hernia recurrence within 1 year was 14.3% and 37.5%. Rate of mesh infection at 30 days was 0% and 10%. Compared to controls, delayed-immediate repairs had a nearly 2-fold index surgical cost. Discussion Although there is an increased cost associated with delayed-immediate repairs, this cost may be offset by the decreased infection, seroma, dehiscence, enterocutaneous fistula formation, and hernia recurrence rate that necessitates future interventions. Further data collection is required to determine if clinical and economic benefit is seen long-term.
