The aim of this study was to examine the outcomes of over a decade's experience utilizing preperitoneal ventral hernia repair (PP-VHR).Background:
PP-VHR was first described by our group in 2006, and there have been no subsequent reports of outcomes with this technique.Methods:
A prospective study of all PP-VHR from January, 2004 to April, 2016 was performed. Multivariate stepwise logistic regression and Cox proportional-hazard models were used to identify predictors of wound complications and hernia recurrence, respectively.Results:
There were 1023 PP-VHRs. Mean age was 57.2 ± 12.6 years, BMI 33.7 ± 11.4 kg/m2, defect size 210.0 ± 221.4 cm2; 23.7% had diabetes, 13.9% were smokers, 68.7% were recurrent, and 23.6% incarcerated. Component separation was required in 43.6%, and a panniculectomy was performed in 30.0%. Wound complication was present in 27.3% of patients, with 1.7% having a mesh infection. In all, there were 53 (5.2%) hernia recurrences and 36 (3.9%) in the synthetic repairs, with a mean follow-up of 27.0 ± 26.4 months. On multivariate regression (odds ratio or hazard ratio, 95% confidence interval), diabetes (1.9, 1.4–3.0), panniculectomy (2.6, 1.8–3.9), and operations requiring biologic mesh were predictors of wound complications, whereas recurrent hernia repair (2.69, 1.14–6.35), biologic mesh (3.1, 1.67–5.75), and wound complications (3.01, 1.69–5.39) were predictors of hernia recurrence.Conclusions:
An open PP-VHR is a very effective means to repair large, complex, and recurrent hernias resulting in a low recurrence rate. Mesh choice in VHR is important and was associated with hernia recurrence and wound complications in this population.
