[Repair of large abdominal wall defects with expanded polytetrafluoroethylene]

Most abdominal wall defects can be repaired by primary closure. However, when the defect is so large that there is tension on closure, use of prosthetic material is indicated. Expanded polytetrafluoroethylene has the advantages of low rates of infection, foreign body reaction and adhesion formation, making it the material of choice for repair of large abdominal wall defects.
