BackgroundLaparoscopic ventral hernia repair (LVHR) is associated with decreased wound morbidity compared to open repair. It remains unclear whether primary fascial closure (PFC) offers any benefit in reducing postoperative seroma compared to bridged repair. We hypothesized that PFC would have no effect on seroma formation following LVHR.MethodsA retrospective cohort study was performed using data from the prospectively maintained Americas Hernia Society Quality Collaborative. All patients undergoing LVHR from 2013 to 2016 were included. The primary outcome was seroma formation, diagnosed either clinically or radiographically. Secondary outcomes included surgical site infections (SSI), surgical site occurrences (SSO), and SSO requiring intervention. Patient characteristics and outcomes were compared between groups with univariate analysis using Pearson's chi-squared or Wilcoxon tests. Multivariable logistic regression controlling for patient and hernia characteristics was then performed to investigate the independent effect of PFC on seroma formation.Results1280 patients were included in the study. 69% (n = 887) underwent PFC. Patients undergoing bridged repairs had slightly larger defects and were more likely to have a recurrent hernia. The overall rate of seroma formation was 10.4% (n = 133). There was no association on univariate analysis between PFC and wound complications. Similarly, on multivariable analysis, PFC had no significant effect on the risk of seroma formation (OR 0.87, 95% CI 0.58-1.31).ConclusionsPFC does not decrease the risk of short-term wound complications. Given that prior studies have also suggested no difference in hernia recurrence, PFC does not appear to improve postoperative outcomes for patients undergoing LVHR.
