Depth of cervical cone removed by loop electrosurgical excision procedure and subsequent risk of spontaneous preterm delivery.

Objective: To investigate the association between cone depth of the loop electrosurgical excision procedure (LEEP) of the cervix and subsequent risk of spontaneous preterm delivery.

Methods: The study included all deliveries in Denmark over a 9-year period, 1997-2005, with information obtained from various public health registries. Of the 552,678 singleton deliveries included in the study, 19,049 were preterm and 8,180 were subsequent to LEEP.

Loop electrosurgical excision of the cervix and risk for spontaneous preterm delivery in twin pregnancies.

Objective: To investigate the association between three cervical procedures (biopsy with no treatment, ablation, and loop electrosurgical excision procedure [LEEP]) and subsequent spontaneous preterm delivery in twin pregnancies using population-based data from various nationwide registries.

Methods: : The study population consisted of all twin deliveries in Denmark during a 9-year period, 1997-2005. Information on the deliveries, including cervical procedures, was obtained from various national registries.

Loop electrosurgical excision of the cervix and subsequent risk for spontaneous preterm delivery: a population-based study of singleton deliveries during a 9-year period.

Objective: Our aim was to assess the association between loop electrosurgical excision procedure (LEEP) and the subsequent risk for spontaneous preterm delivery, with the use of population-based data from various nationwide registries.

Study Design: The study population consisted of all singleton deliveries in Denmark during a 9-year period, 1997-2005. Information on the deliveries that included different cervical procedures was obtained from various national registries.
