Seroma in ventral incisional herniorrhaphy: incidence, predictors and outcome
2009
Abstract Background Factors leading to
seromafollowing ventral incisional herniorrhaphy (VIH) are poorly understood. Methods Between 2004 and 2006, patients were prospectively randomized at 4
Veterans Affairshospitals to undergo laparoscopic or open VIH. Patients who developed
seromaswithin 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
seromasthan those who underwent laparoscopic VIH (23.3% vs 6.8%, P = .011).
Seromapatients 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
seromain VIH.
