Abstract

Background Biologic mesh choice in ventral hernia repair is challenging due to lack of prospective data. This study examines long-term, single-center biologic mesh outcomes. Methods Prospective operative outcomes data was queried for open ventral hernia repair with biologic mesh. Univariate and multivariate analysis were used to compare mesh outcomes. Results In the study, 223 patients underwent open ventral hernia repair with biologic mesh, including 40 with Alloderm, 23 AlloMax, 70 FlexHD, 68 Strattice, and 22 Xenmatrix. Overall, 9.8% had an American Society of Anesthesiology classification of 4, 54.6% with a classification of 3, and 35.6% with a classification of 1 or 2. Operative time averaged 241 minutes with estimated blood loss of 202 mL. Hernia defects averaged 257 ± 245 cm2 with mesh size 384 cm2. Biologic mesh was used as a fascial bridge in 19.6%, component separation was performed in 47.5%, and 82% had concomitant procedure. Inpatient mortality was 1.4%. Hernia recurrence varied significantly by mesh type: 35% Alloderm, 34.5% AlloMax, 37.1% FlexHD, 14.7% Strattice, and 59.1% Xenmatrix (P = .001). The mean follow-up was 18.2 months. After multivariate analysis comparing to Strattice, AlloMax had a 3.4 higher odds ratio for recurrence, FlexHD a 2.9 odds ratio, and Xenmatrix a 7.8 odds ratio. The rate of mesh infections requiring explantation was <1%. Total hospital charges averaged $131,004 ± $143,320. Mean charges varied significantly between meshes; Xenmatrix was the most expensive and AlloMax was the least expensive (P < .05). Conclusion In 223 ventral hernia repair performed with biologic mesh at a tertiary care institution, Strattice, a porcine acellular dermal mesh, had significantly lower odds of hernia recurrence compared with AlloMax, FlexHD, and Xenmatrix. Choice of biologic mesh affects long-term postoperative outcomes in ventral hernia repair.
