Perinatal Outcomes and the Influence of Maternal Characteristics After Roux-en-Y Gastric Bypass Surgery.
Journal of Women's Health 2017 January
OBJECTIVE: Assess the perinatal outcomes and identify what maternal characteristics can influence them in women who had undergone Roux-en-Y gastric bypass (RYGB).
MATERIALS AND METHODS: Analytical, prospective, and longitudinal study with pregnant adult women.
INCLUSION CRITERIA: chronological age >20 years; singleton pregnancy; RYGB surgery before pregnancy.
EXCLUSION CRITERIA: prior malabsorptive or restrictive surgeries; malabsorption syndrome. Data analysis was performed using SPSS statistics software, version 17.
RESULTS: Thirty pregnant women with 30.22 ± 4.38 years, the interval between surgery and the date of last menstrual period was 17.7 ± 9.07 months. The average prepregnancy body mass index was characterized as overweight (27.36 ± 3.26 kg/m2 ), total gestational weight gain was 7.68 ± 3.73 kg. The most common pregnancy complications were anemia (73.3%), urinary tract infection (33.4%), and dumping syndrome (33.4%). As for newborns, 58% were male, with a mean of 39.28 ± 0.84 weeks, 90% were classified as appropriate for gestational age, and 93.4% were born at term with adequate weight (39.28 ± 0.84 weeks and 3128.79 ± 271.49 g). Positive and significant correlation was observed between gestational weekly gain in the first trimester and birth weight (r = 0.42, p = 0.024) and between gestational weekly gain in the second trimester and birth weight (r = 0.48, p = 0.008).
CONCLUSIONS: Despite the completion of RYGB, in general, there was no apparent fetal compromise when considering the analysis of the variables proposed by this study.
