Patterns of Bariatric Surgeries among U.S. Women Diagnosed with Polycystic Ovarian Syndrome

Background: To examine patterns and outcomes of bariatric surgeries, including Roux-en-Y gastric bypass (RYGB), laparoscopic sleeve gastrectomy (LSG) and laparoscopic adjustable gastric banding (LAGB), among women diagnosed with polycystic ovarian syndrome (PCOS). Materials and Methods: Retrospective cohort study using 1998-2011 Nationwide Inpatient Sample data. A total of 52,668 hospital discharge records met eligibility criteria among PCOS women, 18-49 years. Of those, 17,759 had an obesity/overweight diagnosis and 4310 underwent bariatric surgery. Furthermore, 3086 underwent RYGB (n = 2411), LSG (n = 126), or LAGB (n = 549), and were compared to 78,931 non-PCOS controls. Multiple regression models were constructed to examine patient- and hospital-level predictors of obesity/overweight and bariatric surgery, as well as type of bariatric surgery (RYGB, LSG, or LAGB) as a predictor of in-hospital outcomes and PCOS status. Results: The prevalence of obesity/overweight (≈34%) among women diagnosed with PCOS, and of bariatric surgery (≈24%) among women diagnosed with PCOS and obese/overweight varied by patient- and hospital-level characteristics. Women having PCOS and overweight/obesity, who underwent LSG or LAGB, had shorter hospital stay, reduced hospital charges, and better disposition at discharge compared to those who underwent RYGB. PCOS cases and non-PCOS controls experienced similar treatment selection and in-hospital outcomes after bariatric surgery. Also, PCOS cases and non-PCOS controls experienced similar in-hospital outcomes after undergoing RYGB, LSG, or LAGB. Conclusions: Compared to RYGB, LSG and LAGB resulted in improved in-hospital outcomes among obese/overweight PCOS and non-PCOS patients. Further research is needed to examine health care disparities in the context of PCOS, obesity/overweight, and bariatric surgery.
