The surgical procedure for inguinal tension-free repair is simply a 5-cm-long surgical incision made lateral to the pubic symphysis in the inguinal region, which requires good exposure of the pubic symphysis and the internal ring of the hernia. Then the spermatic cord is separated by incision along the tendon membrane of the external oblique muscle of the abdomen, and the spermatic cord is lifted and then freed upward from the inguinal floor about 3 cm, and the spermatic cord is freed from the bottom of the inguinal canal together with the covered levator muscle until the internal ring of the hernia is treated at 2 cm from the pubic symphysis, and the hernia defect is ligated and the hernia sac is returned to the abdominal cavity. A soft tissue patch should be applied to cover the hernia sac, and then the patch is fixed and sutured to the pubic bone and the anterior rectus abdominis sheath, then the abdomen is closed and the external oblique abdominal muscle, subcutaneous tissue and skin are sutured in accordance.
