چکیده
Objective: To analyze the obstetric and neonatal outcomes in pregnancies after Roux-en-Y Gastric Bypass (RYGB) compared with matched control pregnancies. Methodology: A cross-sectional study of the analytical type with pregnant women matched by age and pre-pregnancy body mass index (BMI) was carried out. Group 1 (G1) comprised 60 pregnant women who did not previously undergo RYGB and Group 2 (G2) 30 pregnant women who previously underwent RYGB. Results: In G1 mean age was 29.2 ± 4.9 and mean pre-pregnancy BMI was 26.3 ± 3.34 G2. In G2 was 30.3 ± 4.4 and 27.4 ± 3.3, respectively. In relation to gestational intercurrences, 36.7% of pregnant women in G2 showed urinary tract infection (UTI) (p<0.001), 76.7% anemia (p<0.001). Both in G1 and G2, NBs were classified as having appropriate birth weight. As regards, the gestational age at birth, 88.3% of NBs in G1 and 96.5% in G2 were considered born at term. Among the NBs in G1, a total of 81.7% was classified as AGA NBs, 10% as LGA NBs and 8.3% as SGA NBs. In G2, 72.4% were classified as AGA NBs and 24.1% as SGA NBs, (p=0.036). Conclusion: No compromise of perinatal outcomes was observed. However, it was observed the significantly higher prevalence of anemia and UTI in G2 and Due to decreased the incidence of macrosomia, the chances of normal birth (NB) increases after RYGB. Neonatal outcomes and course of pregnancy improve, if conception occurs minimum 18 months after surgery.
