Obstetric outcomes after cervical loop electrosurgical excision procedure.

OBJECTIVES

This study aimed to investigate whether a history of loop electrosurgical excision procedure (i.e., conisation) affects obstetric and neonatal outcomes.

METHODS

A retrospective cohort study was carried out in Västernorrland county, Sweden. 57 nulliparous women with singleton pregnancies and previous conisation were compared with 100 age-matched pregnant controls without history of conisation.

RESULTS

There was significantly lower gestational age by delivery (p = 0.036), however, the premature delivery rate was not different. Caesarean section was also less frequent (OR: 0.29, 95% CI: 0.081-1.04, p = 0.047) in the conisation group than those in the control group. There were no differences in neonatal outcomes.

CONCLUSIONS

Previous conisation does not affect the risk of prematurity or cervical dilatation during the first stage of labour. Women with history of conisation had a lower rate of caesarean section, and lower gestational age by delivery.
