title: Seroma in ventral incisional herniorrhaphy: incidence, predictors and outcome.
abstract: BACKGROUND
  Factors leading to seroma following ventral incisional herniorrhaphy (VIH) are poorly understood.
  
  
  METHODS
  Between 2004 and 2006, patients were prospectively randomized at 4 Veterans Affairs hospitals to undergo laparoscopic or open VIH. Patients who developed seromas within 8 weeks postoperatively were compared with those who did not. Multivariate analyses were performed to identify predictors of seroma.
  
  
  RESULTS
  Of 145 patients who underwent VIH, 24 (16.6%) developed seromas. Patients who underwent open VIH had more seromas than those who underwent laparoscopic VIH (23.3% vs 6.8%, P = .011). Seroma patients had hernias that were never spontaneously reducible (0% vs 21%, P = .015), had more abdominal incisions preoperatively (mean, 2.4 vs 1.8; P = .037), and were less likely to have drain catheters placed than those without seromas (30.0% vs 63.1%, P = .011). In multivariate analyses, open VIH predicted seroma (odds ratio, 5.5; 95% confidence interval, 1.6-18.8), as well as the specific hospital at which the procedure was performed. Spontaneous resolution occurred in 71% of seromas; 29% required aspiration.
  
  
  CONCLUSIONS
  Procedural characteristics and hernia characteristics rather than patient comorbidities predicted seroma in VIH.
