The introduction of mesh reinforcement for groin hernia repair has resulted in reducing the rate of recurrences and chronic pain. Moreover, laparoscopic repair techniques made it possible to place the mesh in de pre-peritoneal space by a transperitoneal (TAPP) or pre-peritoneal (TEP) approach. These minimally invasive techniques are not only associated with less chronic pain of numbness, but also with an earlier return to normal activities or work. A favor for one of the two techniques has not yet been proven.
