Abstract

Introduction Pregnancy in women submitted to bariatric surgery is increasing. Recommendations for surveillance of these pregnancies have been suggested, but an adequate time interval from surgery to conception, to avoid perinatal negative outcomes, is still controversial.Material and methods Medical records of pregnancies in women with previous bariatric surgery were retrieved and outcomes were assessed according to three different time thresholds (12, 18 and 24 months). The association between time from surgery to conception and the presence of adverse outcomes was analysed.Results Eighty-six pregnancies were assessed. Weight gain was higher (p = 0.014) and more adequate (p = 0.041) when pregnancy occurred more than 12 months after surgery. Foetal growth percentile was lower when pregnancy was achieved before 24 months following surgery (p = 0.021). No differences among groups were found in other assessed outcomes (BMI, gestational age at delivery, type of delivery, gestational diabetes, pregnancy hypertensive disease, anaemia, preterm delivery, foetal weight, foetal growth restriction, Apgar score, admission to neonatal intensive unit) in all considered thresholds. No association between time from surgery to conception and the presence of adverse outcomes was found.Conclusion Despite differences found in maternal weight gain and foetal growth percentile, our study does not support the recommendation to delay pregnancy based on a fixed deadline. Other factors, including a more individualised approach, need to be considered.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
