Trends in Attempted Vaginal Delivery among Pregnancies Complicated by Gastroschisis, 2014 to 2020

Abstract

Objective Gastroschisis is a full-thickness congenital defect of the abdominal wall through which intestines and other organs may herniate. In a prior analysis, attempted vaginal delivery with fetal gastroschisis appeared to increase through 2013, although cesarean delivery remained common. The objective of this analysis was to update current trends in attempted vaginal birth among pregnancies complicated by gastroschisis. Study Design We performed an updated cross-sectional analysis of live births from 2014 and 2020 using data from the U.S. National Vital Statistics System and evaluated trends in attempted vaginal deliveries among births with gastroschisis. Trends were evaluated using joinpoint regression. We constructed logistic regression models to evaluate the association between demographic and clinical variables and attempted vaginal delivery in the setting of gastroschisis. Results Among 5,355 deliveries with gastroschisis meeting inclusion criteria, attempted vaginal delivery increased significantly from 68.9% to 75.1%, an average annual percent change of 1.7% (95% confidence interval [CI], 0.8–2.5). Among gastroschisis-complicated pregnancies, patients 35 to 39 years old (adjusted odds ratio [aOR], 0.53; 95% CI, 0.37–0.79) and Hispanic race/ethnicity (aOR, 0.69; 95% CI, 0.58–0.62) were at lower likelihood of attempted vaginal delivery in adjusted analyses. Conclusion These findings suggest that vaginal delivery continues to increase in the setting of gastroschisis. Further reduction of surgical delivery for this fetal defect may be possible. Key Points
