Mesh graft infection following abdominal hernia repair: risk factor evaluation and strategies of mesh graft preservation. A retrospective analysis of 476 operations.

Background: Mesh graft infection after prosthetic hernia repair is a challenging complication usually treated by mesh removal. The aim of this study was to identify risk factors associated with mesh infection and to assess the efficacy of conservative wound therapy in preserving an infected mesh.

Methods: We performed a retrospective analysis of 476 consecutive patients with incisional hernia who received mesh graft repair between February 1, 2000 and February 28, 2005 at our institution using chart review and clinical investigation.
