Abstract

Introduction: Of all hernia types, large ventral hernias have the most impact on patient quality of life, however they are also the most difficult type of hernia to repair and are associated with high rates of complications. This case series describes repair of large ventral hernias with an ovine reinforced biologic in a complex patient cohort with comorbidities and concomitant procedures.

Methods: The author performed bridged repair with an ovine reinforced biologic in 19 consecutive high-risk patients over a 5-year period. In all cases the reinforced biologic was used as an underlay.

Outcomes: Of the 19 patients, six (32%) experienced a surgical site occurrence including infection, seroma, abscess, fistula, bioloma, or bowel obstruction. Three patients (16%) had recurrences with two out of three of the recurrences occurring within 6 months of surgery.

Conclusions: Rates of SSO's and recurrences using ovine reinforced tissue matrix (RTM) were in line with or better than other published studies of bridged repair utilizing biologic or synthetic mesh reinforcement. Ovine RTM's should therefore be considered in complex large ventral hernia repairs.
