title: [Impact of bariatric surgery on obstetric prognosis].
abstract: OBJECTIVE
  Assessment of pregnancy outcomes after bariatric surgery and analysis of follow-up particularities of such pregnancies.
  
  
  METHODS
  A retrospective study of 63 post-bariatric surgery pregnancies compared to 259 pregnancies of obese un-operated patients. Pregnancy outcomes, neonatal datas, delay influence between surgery and pregnancy beginning, bariatric surgery type and gastric banding (GB) loosening consequences were analysed.
  
  
  RESULTS
  In the surgical brand were developed less gestational diabetes (DG) (P=0,05), deliveries were more often normal (P=0,004) and births shown less macrosomias and small for gestational age newborns (P=0,04). Neonatal state was improved among operated patients: less Apgar scores less than 7 at 1 minute (P=0,05) and less cord blood pH less than 7,2 (P=0,03). They gained more weight during the pregnancy (P=0,0003) and only 53% had a nutritional management and assessment. Patients with GB loosening gained more weight (P=0,0003). Lastly, there were no difference due to the different bariatric surgery techniques or nutritional follow-up in the pregnancy course and neonatal state.
  
  
  CONCLUSIONS
  Bariatric surgery improves obstetric and neonatal prognosis. Improvements have to be developed in the multidisciplinary follow-up in order to avoid nutritional deficiencies or important weight gain pregnancy in case of GB.
