The authors present 44 patients operated for hernias (inguinal and/or femoral) with a median pre-peritoneal approach positioning a mersilene mesh with Stoppa's technique. The results are very interesting considering that the hernias treated are all at high risk of recurrence. We had 4 complications (1 bleeding and 3 wound infections) that were conservatively treated, no mortality at all. The follow-up was of 12 months (mean) and no recurrence was discovered.
