Objective: To investigate the effect of cervical cone excision on cervical canal length in patients with high cervical intraepithelial neoplasia. Methods: 30 cases of patients with high-grade cervical intraepithelial neoplasia who admitted in our hospital and underwent cervical cone resection were selected as the experimental group and 30 cases of healthy pregnancy at the same period were selected as the control group. The experimental group was given cervical conization. The cervical canal length of patients in the experimental group, the cervical canal length of successful pregnancy patients, pregnancy and pregnancy outcome pregnancy of the two groups were detected after treatment. Results: Compared with the control group ,the cervical tube length level was significantly lower in the experimental group after treatment (P<0.05);the cervical tube length of successful pregnancy underwent cervical conization at 12 weeks , 20 weeks, 28 weeks after pregnancy showed no significant difference (P>0.05), the successful pregnancy rate of experimental group after surgery was lower(P<0.05), the incidence of pregnancy with preterm premature rupture of membranes, umbilical cord around the neck prematurity and cases of term delivery number between experimental and control groups showed no significant difference between two groups(P>0.05). Conclusion: The cervical canal length level of patients with high-grade cervical intraepithelial neoplasia was lower after cervical conization, the successful pregnancy rate was low, the pregnancy cervical tube length and the rate of preterm birth had no difference compared with normal pregnant women.
