Abstract

OBJECTIVES:

To determine the effect of cervical cerclage on obstetrical complications and perinatal outcomes of patients following conization.

DESIGN:

A retrospective population based cohort study.

SETTING:

Tertiary academic medical center that covers all the deliveries of the region.

POPULATION:

All patients with previous cervical conization who delivered between the years 1994-2011.

METHODS:

A retrospective population based study.

MAIN OUTCOME MEASURES:

The effect of cerclage placement on the rate of preterm birth.

RESULTS:

During the study period there were 109 deliveries of patients following a cervical conization. Cervical cerclage was placed in 22 deliveries that served as the study group and the rest (nā€‰=ā€‰87) served as the comparison group. The rate of early preterm delivery (PTD;ā€‰ <34 weeks) was significantly higher in women who had a cerclage. In a logistic regression model, cerclage was found to be an independent risk factor for early PTD.

CONCLUSION:

Cerclage is an independent risk factor for early PTD In patients who had a conization due to CIN.

KEYWORDS:

Cervical cerclage; cervical intraepithelial neoplasia; conization; early preterm birth
