Pregnancy after 24 Postoperative Months of Roux-En-Y Gastric Bypass Presents Risk of Pregnancy Complications Similar to Pregnancy within the First Postoperative Year
Background: To assess the influence of the time interval between pregnancy and the Roux-en-Y gastric bypass (RYGB) on maternal-infant complications. Methods: This is an analytical, longitudinal and retrospective study comprising 42 pregnant women who had previously undergone RYGB, subdivided according to the time interval between pregnancy and bariatric surgery: ≤12 months (G1), >12 and <24 months (G2) and ≥24 months (G3). Anthropometric variables of mothers, newborns and information on pregnancy complications were collected. Results: G1 was the group more likely to develop urinary tract infection, dumping syndrome and inadequacy of birth weight than G2. Pregnancy complications were similar and >80.0% both in the first 12 months and after 24 months of the RYGB and the smallest percentages occurred in the time interval of 12–24 months after it. In addition, the percentage of neonatal complications was the highest in G1 when compared to the other times studied. Conclusion: Our findings indicate less predisposition to maternal-infant complications in pregnancies occurring in the time interval of >12 and <24 months and suggest that pregnancy after 24 months can be as harmful as pregnancies occurring before the first 12 postoperative months, since a great catabolism occurs at this time as it has been shown in the literature.
