Anterior rectus sheath in inguinal hernia repair: preliminary study.

Inguinal hernia repair using the anterior rectus sheath flap represents a tension-free repair with potential advantages (no foreign material or tension on the suture line). The aim of this research was to evaluate the method of inguinal hernia repair using the anterior rectus sheath and to compare it with tension-free mesh repair (modified Lichtenstein repair). In total, 62 patients were evaluated.
