title: [Problem of recurrent incisional hernia after mesh repair of the abdominal wall].
abstract: BACKGROUND
  Depending on the surgical technique, mesh material and follow-up, the figures for recurrences of incisional hernia vary from 0 to 31%. What are the reasons for recurrences, and which options exist for more successful therapy?
  
  
  METHODS
  Fourteen operations for recurrences after mesh repair of incisional hernias were analyzed retrospectively and correlated with a literature review of the years 1990-2000.
  
  
  RESULTS
  An inadequate surgical technique is the main reason for recurrences after the use of polypropylene or polyester, but with PTFE, it is instead the properties of the material. In our patients we found central mesh recurrences. The first results with laparoscopic technique are very promising.
  
  
  CONCLUSIONS
  Open incisional hernia mesh repair should be performed with the sublay technique, preferably with polypropylene; the use of polyester can be recommended only with reservations and the use of PTFE ought to be limited to very few indications. The entire incision should always be prepared with safe fixation of the mesh and wide overlap of the hernia. Recurrences after polypropylene implantation can be treated with additional mesh; concerning PTFE, a different material is recommended. A final evaluation of laparoscopic mesh repair cannot be assessed yet.
