Does the Uterine Cervix Become Abnormally Reinnervated After Subtotal Hysterectomy and What Is the Association With Future Trachelectomy?

Nerve fibers in the cervical stump after supracervical hysterectomy are significantly increased in women undergoing trachelectomy for pain indications compared with those who underwent trachelectomy for nonpain indications and controls. Although not statistically significant, endometriosis may be an independent risk factor for increased nerve fibers. These histopathologic observations may support the idea that the cervix should be removed in women undergoing hysterectomy for chronic pelvic pain or endometriosis.
