Étude cas-témoin des conséquences obstétricales de la conisation

Abstract

Evaluate the obstetrical outcomes in the case of women with a history of conization. Determine the role of the cone length in the obstetrical issue. Retrospective case-control study including the patients (n=39) who had undergone a conization in a university hospital between January 2002and January 2012. The obstetrical outcomes have been compared to those from a control group (n=78). Into the exposed group the obstetrical outcomes has been compared based on the cone length. Thirty-one patients delivered after a conization (39deliveries). The obstetrical outcomes have been significantly increased in the exposed group: preterm delivery before 37weeks gestation (25.6% vs 7.7%, P=0.01), before 32weeks gestation (15.4% vs 1.3%, P=0.005) and between 28weeks gestation (10.2% vs 0%, P=0.01), premature onset of labor before 32weeks gestation (12.8% vs 1.3%, P=0.01) and before 28weeks gestation (12.8% vs 0%, P=0.01) and preterm premature rupture of membranes before 37weeks gestation (20.5% vs 1.3%, P<0.001). There was no significant difference for a length cone more than 1.5cm. Our study showed that a history of conization is an obstetrical risk factor to consider in the management of a subsequent pregnancy.
