Abstract

Purpose

To examine the effect of bariatric surgery (BS) on obstetric and neonatal outcomes in patients with polycystic ovary syndrome (PCOS).

Methods

A retrospective population-based cohort study utilizing the Healthcare Cost and Utilization Project Nationwide Inpatient Sample database, including women who delivered in the third trimester or had a maternal death in the USA (2004–2014). We compared obstetric and neonatal outcomes between groups in three analyses: (1) Primary analysis—women with an ICD-9 PCOS diagnosis who underwent BS compared to pregnant PCOS patients without BS. (2) Sub-group analysis—PCOS women with BS compared to obese PCOS women (body mass index (BMI) ≥ 30 kg/m2) without BS. (3) Women with and without PCOS who underwent BS.

Result

In the primary analysis, pregnant PCOS women who underwent BS (N = 141), compared to pregnant PCOS women without BS (N = 14,741), were less likely to develop pregnancy-induced hypertension (PIH) (9.2% vs. 16.2%, respectively, aOR 0.39, 95% CI 0.21–0.72) and gestational diabetes mellitus (GDM) (9.9% vs. 18.8, aOR 0.40, 95% CI 0.23–0.70). In the sub-group analysis, PCOS women with BS, compared to obese PCOS women without BS (N = 3231), were less likely to develop gestational hypertension, preeclampsia, and preeclampsia or eclampsia superimposed on hypertension (P < 0.05). Lastly, PCOS patients with BS had a higher cesarean section rate when compared to non-PCOS patients with BS (N = 9197) (61.7% vs. 49.2%, aOR 1.48, 95% CI 1.05–2.09), with otherwise comparable obstetric and neonatal outcomes.

Conclusions

BS in PCOS patients was associated with reduced risks for GDM and PIH when compared to PCOS controls without BS and reduced risk for gestational hypertension, preeclampsia, and preeclampsia or eclampsia superimposed on hypertension when compared to obese PCOS controls without BS. Moreover, BS was associated with reduced inherent pregnancy risks of PCOS, almost equating them to those of non-PCOS counterparts.
