A bioprosthetic was used in 16 patients to prevent the occurrence of a parastomal hernia. The median follow-up was 38 months. There were no mesh-related complications, and no parastomal hernias occurred. On value analysis, to be cost-effective, the percentage of patients who would have subsequently needed surgical repair of a parastomal hernia would have to be in excess of 39%or the bioprosthetic would have to cost less than $2,267 to $4,312.
These data show the safety and efficacy of using a bioprosthetic at the time of permanent stoma creation in preventing a parastomal hernia and defines the parameters for this approach to be cost-effective.
