title: Prolene Hernia System compared with Lichtenstein patch: a randomised double blind study of short-term and medium-term outcomes in primary inguinal hernia repair.
abstract: BACKGROUND
  Refinements in the configuration of mesh may ease handling and placement and reduce postoperative discomfort.
  
  
  METHODS
  A total of 206 patients were randomly and blindly allocated to receive the Prolene Hernia System (PHS) or Lichtenstein patch. Collected data included: surgical incision size, procedure time, pain scores, analgesic medication, complications, return to activity and work, and quality of life as measured by Short-Form 36 on days 3 and 14.
  
  
  RESULTS
  Immediate post-operative pain was significantly lower with PHS than with the patch. The proportion of PHS patients taking longer than 3 days to return to normal activity was 15.5%, compared to 28.4% of patch patients. Operating time was significantly shorter with PHS (34.1 vs. 38.3 min). There was no treatment effect on any of the quality of life scales as measured by Short-Form 36. There were two recurrences in the patch group.
  
  
  CONCLUSIONS
  The study indicates a reduction in operating time (4 min) and postoperative recovery with the PHS compared with patch.
