Use and Indications of Human Acellular Dermis in Ventral Hernia Repair at a Community Hospital

Background. To evaluate the use, indications, and short-term outcomes for human acellular dermis. Methods. We retrospectively reviewed patients having human acellular dermis placed for ventral hernia repair from January 2008 through October 2009. Demographic information, operative details, and outcomes of patients with and without recurrences were compared; a P value <0.05 was considered significant. Results. 115 patients met inclusion criteria. The average age was 60 years (range, 24–89). The technique of repair included primary repair with overlay of mesh in 76%, bridge repair in 13%, and underlay in 11%. Average cost of mesh per operation was $3,709 (range $191–10,630). Open repairs were performed in 90% of patients with addition of component separation in 12%. At an average of 13 months, 58 patients were available for followup (50%), with a 47% recurrence rate. The morbidity rate was 48% and the mortality rate was 2%. Technique of repair was the only significant risk factor for recurrence with bridge repairs associated with a higher rate of recurrence (P < 0.05). Conclusions. The use of biologic grafts for ventral hernia repair is becoming more popular especially in clean cases. Although followup is limited, there remains a high recurrence rate associated with the use of human acellular dermis.
