abstract

  • BACKGROUND: Bariatric surgery is performed mostly on obese women of reproductive age. Many authors have studied pregnancy outcomes after bariatric surgery. Only a small number of studies have analyzed the impact of maternity on the results of bariatric surgery. OBJECTIVES: To study the effect of pregnancy on long-term outcomes of bariatric surgery. SETTING: Lille University Hospital. METHODS: A retrospective study was conducted on 591 women aged 18 to 42 years who had undergone laparoscopic adjustable gastric band (LAGB) surgery or laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery between 1996 and 2012. A comparison of the results after a 5-year follow-up was performed between patients who became pregnant after their bariatric surgery (pregnant group, n = 84) and postoperative nonpregnant women (nonpregnant group, n = 507). RESULTS: At the 5-year visit, 84.8% patients were seen. The preoperative body mass index (BMI) was the same in the 2 groups (pregnant group: 47.8±6.9 kg/m(2); nonpregnant group: 47.5±7.2 kg/m(2); P = .755). The percentage of excess weight loss (%EWL) was lower in the pregnant group at 2 years (pregnant group = 45.9±24.6%; nonpregnant group = 56.9±28.6%, P = .002) but was similar at 5 years (47.7±27.7% versus 49.9±28.9%, P = .644). The decrease in co-morbidities was similar after 5 years. The gestational weight gain (GWG) was higher when the band was deflated during pregnancy (GWG =+12.7±10.5 kg) compared to the band without fluid removal (GWG =+4.9±7 kg) or laparoscopic Roux-en-Y gastric bypass (GWG =+4.4±1.1 kg) (P< .05). CONCLUSIONS: Pregnancy after bariatric surgery slows down postoperative weight loss but does not affect weight results at 5-year follow-up.
