Loop electrosurgical excision procedure of the cervix and time of deliveryin subsequent pregnancy

Objective: To study the effect of the loop electrosurgical excision procedu re (LEEP) on gestational age at delivery in the subsequent pregnancy. Metho d: Identification of women with LEEP. Chart analysis and inquiry into gesta tional age at the subsequent delivery. Exclusion of first trimester abortio ns, multiple gestations, cold knife conizations and women over 40 years dur ing LEEP. For comparison, 40 weeks was used as the mean date of delivery in a normal population. Wilcoxon signed rank test was used and P < 0.05 was c onsidered significant. Result: Fifty-six women delivered after LEEP. Seven delivered preterm of whom three were induced and one had a history of prete rm delivery. Deliveries prior to 32 weeks of gestation did not occur. Mean gestational age at delivery was 39 2/7 weeks (95%CI: 38 5/7-39 6/7) which i s significantly earlier (P = 0.03) than the hypothetical 40 weeks. Conclusi on: After LEEP, deliveries prior to 32 weeks did not occur. Gestational age at delivery was only 5 days earlier than expected. LEEP cannot be consider ed a risk for early preterm delivery.
