With the increase in cervical disease, cervical surgery, and the need to have children after surgery, the proportion of pregnancies after cervical resection has increased, and the impact of this type of surgery on the function of the cervix, especially on pregnancy outcomes, is of great concern. The main problems are as follows: 1. Preterm delivery due to cervical insufficiency during pregnancy due to partial removal of cervical tissue, shortening of the length of the cervix and reduction of the cervical support. The height of the cervical conization and the size of the cervical conization are associated with poor pregnancy outcome. 2. The removal of part of the mucus-secreting cervical tissue leads to a decrease in the secretion of cervical mucus containing bacteriostatic substances, thus making it easy for pathogenic microorganisms to invade and making pregnant women susceptible to subclinical infections, thus increasing the risk of miscarriage, premature rupture of membranes and preterm delivery. It is advisable to have colposcopy and subsequent cervical conization performed by the same experienced specialist in order to preserve more normal cervical tissue during the operation. 3. The effect on the mode of delivery, cervical conization removes part of the connective tissue of the official cervix, and scar tissue may be formed after the repair of the wound, making the cervical canal less elastic, which may affect the dilation of the cervix during labor and cause cervical obstructed labor.
