title: Ring-reinforced prosthesis for paracolostomy hernia.
abstract: BACKGROUND
  The reported recurrence rate after paracolostomy hernia repair, with or without mesh, varies between 47 and 100%. We developed a polypropylene mesh prosthesis with a central opening, reinforced with a polypropylene ring, that can be implanted suprafascially through a mucocutaneous incision.
  
  
  METHODS
  The results of a consecutive series of 46 patients with paracolostomy hernia, who were implanted with this prosthesis between October 1988 and November 2000 in 12 hospitals, were analyzed. The mean follow-up was 5 (range 1-13) years.
  
  
  RESULTS
  The early infection rate was 4.3%. Two patients were lost to follow-up. The late infection rate was 2.3%. Seven patients (15.9%) developed a recurrent parastomal hernia and were all reoperated. The prosthesis was definitively removed in 10 patients.
  
  
  CONCLUSIONS
  Although implantation of this new prosthesis is not without complications, it offers the lowest reported recurrence rate until now.
