Effect of different conization ranges on pregnancy outcomes

Abstract

Purpose: To analyze the influence of different conization on pregnancy outcomes. Methods: The data of 78 women at childbearing age having cervical conization in our hospital from January 2013 till December 2015, was collected and analyzed. The control group comprised of 80 women of childbearing age with matched clinical data, who did not undergo cervical conization. Data on the conization procedure were analyzed and pregnancy and obstetric outcomes were assessed. using the. Comparisons were made using the 2test or the Fisher exact test and Student T-test as appropriate. Results: Cold knife cervical conization prolonged the time to conception in patients. Following the procedure, the incidence of premature delivery and premature rupture of membranes were significantly increased as also the rate of early abortions. The depth and circumference of conization was found to be directly correlated with the rate of premature delivery and premature membrane rupture, but not with fetal growth restriction and macrosomia. Conclusion: The depth and circumference of resection should be based on the type of cervical lesions as well as the prognosis and the future pregnancy plans of the patients.
