The ideal graft material for pelvic reconstructive surgery remains undetermined. The purpose of this study was to present data on novel composite biologic/synthetic grafts during use in abdominal sacrocolpopexy.
A case series of 90 patients undergoing abdominal sacrocolpopexy with composite biologic/synthetic grafts was conducted. The primary outcome was graft erosion. Assuming a 3% risk of reoperation for mesh erosion, the number needed to treat with a composite graft in order to avoid erosion risk from a synthetic-only graft was calculated. The cost of a composite graft was compared to reoperation costs for mesh erosion of a synthetic-only graft.
Zero patients (N = 90) undergoing abdominal sacrocolpopexy with a composite biologic/synthetic graft experienced graft erosion. Based on existing data, thirty-three patients would need to be treated with a composite graft to avoid one mesh erosion from a synthetic-only graft. If a $500 composite graft is used, the cost of reoperation performed abdominally is higher.
This study introduces a novel biologic/synthetic composite graft that offers the advantage of low erosion risk during use in abdominal sacrocolpopexy. Combined grafts may also be cost-effective. Future research should focus on exploring the role of these durable, yet low erosion risk grafts to potentially promote improved safety for our patients and cost savings for society.
