Abstract: ［Abstract］ Over the past hundred years, the main focus in inguinal hernia was how to implement a flawless surgery and how to reduce postoperative recurrence, while the existence and hazard of postoperative chronic pain were always ignored. Until the 1980s, the problem of postoperative chronic pain has emerged after the effective control over the recurrence rate after herniorraphy. How to reduce its incident rate has become a hot research area at present. By literature reviewing, good understanding of neuroanatomy in inguinal area and proficiency of surgical treatment and intraoperative standard operation were able to lower the incident rate of postoperative chronic pain after inguinal hernia tension?free herniorraphy.
