Despite all the progress made in inguinal hernia surgery driven by the development of meshes and laparoendoscopic operative techniques, the proportion of recurrent inguinal hernias is still from 12% to 13%. Recurrences can present very soon after primary inguinal hernia repair generally because of technical failure. However, they can also develop much later after the primary operation probably due to patient-specific factors. Supported by evidence-based data, this review presents the surgical risk factors for recurrent inguinal hernia after the primary operation. The following factors are implicated here: choice of operative technique and mesh, mesh fixation technique, mesh size, management of medial and lateral hernia sac, sliding hernia, lipoma in the inguinal canal, operating time, type of anesthesia, participation in a register database, femoral hernia, postoperative complications, as well as the center and surgeon volume. If these surgical risk factors are taken into account when performing primary inguinal hernia repair, a good outcome can be expected for the patient. Therefore, they should definitely be observed.
