Abstract: Cervical intraepithelial neoplasia treated by partial resection of cervix can effectively reduce the incidence of cervical invasive carcinoma. Early cervical carcinoma treated by radical trachelectomy can significantly reduce the mortality of cervical invasive carcinoma. However, these two types of operation are likely to lead to cervical insufficiency after surgery. Partial resection of cervix reduces the cervical supporting capacity due to the removed cervical tissue, which results in late abortion and premature delivery, and influences the reproductive outcome. Cervical cerclage can prolong the cervical length, and reduce the rates of premature delivery and midtrimester abortion. Therefore, the patients with fertility requirements need the preventive or therapeutic cervical cerclage. In order to prevent the cervical insufficiency caused by the radical trachelectomy, permanent cervical cerclage was performed with non-absorbable suture routinely. However, the second-trimester miscarriage or premature delivery is still encountered after surgery. Trachelorraphy is a safe, repeatable and easy to perform operation, to prevent the failed cervical cerclage. It is benefit to improve reproductive outcome for those women with the cervical insufficiency related to radical trachelectomy.
