Impact of Roux-en-Y gastric bypass and sleeve gastrectomy on fetal growth and relationship with maternal nutritional status.

摘要: Abstract Background There is a lack of evidence on whether sleeve gastrectomy (SG), which induces fewer nutritional deficiencies than Roux-en-Y gastric bypass (RYGB), also affects fetal growth (FG). Objectives To compare neonatal outcomes after RYGB and SG to assess the impact maternal alterations FG both procedures. Setting University Hospital, France. Methods Women with singleton pregnancies who had at least 1 evaluation in our institution between 2004 2017 were included. was assessed birth weight (BW) BW-Z score (adjusted for sex term), defined according standard pregnancy-specific norms. Results During study period 123 included, 77 46 SG. Weight loss higher (45.6 ± 12.4 versus 39.5 13.7 kg, P = .02), but mean before pregnancy gain during similar. Mean BW (3026 677 3162 712 g), Z-score incidence small gestational age (24% 19%) not significantly different number second trimester similar (2.2 1.5 2.1 1.2 specific norms), affected parameters differed Urinary urea (R = .285, P = .04) positively correlated In contrast, serum iron negatively associated Z-score. Conclusion restriction occurs RYGB. bariatric surgery protein supply status.
