The document discusses two techniques for treating primary inguinal hernias - the Lichtenstein vs Rutkow-Robbins technique. A 2006 study by Bolognini et al found no statistically significant differences in long-term results between the two groups. Additionally, a 2007 study by Frey et al also found the Lichtenstein operation and mesh plug repair to have comparable perioperative complications and recurrence rates.
