The document discusses two techniques for treating primary inguinal hernias - the Lichtenstein vs Rutkow-Robbins technique. Two studies are referenced that found no statistically significant differences between the techniques in long-term results or perioperative complications and recurrence rates. Both techniques appear comparable for treating primary inguinal hernias.
