Influence of preservation versus division of ilioinguinal, iliohypogastric, and genital nerves during open mesh herniorrhaphy: prospective multicentric study of chronic pain.
To evaluate whether the various surgical treatment reserved for ilioinguinal, iliohypogastric, and genital branch of the genitofemoral nerves, during open hernia mesh repair, is effective in reducing chronic postoperative pain. ⋯ The present findings indicate that identification and preservation of nerves during open inguinal hernia repair reduce chronic incapacitating groin pain and that, in the majority of patients with chronic pain at 6 months, the pain at 1 year is resolved only with conservative or medical treatment.
