Factors affecting obstetric outcomes in patients who underwent cold-knife and loop electrosurgical excision procedure conization due to cervical intraepithelial neoplasia 2 or cervical intraepithelial neoplasia 3

To determine factors affecting obstetric outcomes in pregnancies after conization by loop electrosurgical excision procedure (LEEP) or cold-knife conization (CKC) due to cervical intraepithelial neoplasia. The maternal and clinical characteristics and obstetric outcomes of CKC, LEEP and control groups were evaluated and compared. Risk factors for adverse pregnancy outcomes were evaluated using multiple logistic regression analyses. The incidence of preterm delivery, preterm premature rupture of membranes (PPROM), low APGAR scores, fetal mortality, and late-period spontaneous abortus was highest in patients who underwent CKC (p
