BackgroundThe morbidity and mortality associated with acute primary ventral hernia repair have not been well described. We examined the rate of surgical site infection (SSI), hernia recurrence, and mortality in acute versus elective primary ventral hernia repair and identified predictors of morbidity and mortality after primary ventral hernia repair.MethodsA retrospective study on all patients undergoing open primary ventral hernia repair at a single institution (2000-2010) was performed. Primary outcomes were mortality at any time, SSI, and recurrence. Survival analysis for the entire, unmatched sample was conducted. We performed a risk-adjusted analysis of outcomes using two methods as follows: (1) case matching and (2) propensity score-adjusted regression model.ResultsWe identified 497 patients; 57 (11%) underwent acute primary ventral hernia repair. For the entire cohort, survival was worse for patients undergoing acute repair (log rank, 0.03). Following case matching on age, body mass index, American Society of Anesthesiologists score, and hernia size, there was no difference in mortality, SSI, or recurrence. After propensity score adjustment, acute surgery was not a predictor for mortality or SSI; however, incarcerated hernias predicted recurrence.ConclusionAfter risk adjustment, acute primary ventral hernia repair was not associated with higher mortality, infection, or recurrence compared with elective repair.Level Of EvidenceTherapeutic study, level IV.
