title: Pregnancy after laparoscopic bariatric surgery: comparative study of adjustable gastric banding and Roux-en-Y gastric bypass.
abstract: BACKGROUND
  Approximately 80% of patients undergoing bariatric surgery are women, and about one half of these are of reproductive age. The purpose of the present study was to compare laparoscopic adjustable gastric banding (LAGB) and laparoscopic Roux-en-Y gastric bypass (LRYGB) in a series of morbidly obese women with respect to maternal and neonatal outcomes at a university hospital in France.
  
  
  METHODS
  From January 2004 to December 2008, the data from women who had undergone LAGB or LRYGB at our center and were pregnant were collected, including age, parity, gravidity, weight, body mass index (BMI) before surgery and at scheduled intervals after surgery (1, 3, 6, 12, and 18 mo and yearly thereafter), interval from surgery to conception, weight and BMI at conception, weight and weight gain during pregnancy, weight and BMI at 2 weeks after pregnancy, complications during pregnancy, gestational age, method of delivery, fetal birth weight, and fetal outcome.
  
  
  RESULTS
  There were 42 pregnancies in 36 women, 22 in women who had undergone LAGB and 20 who had undergone LRYGB. The LAGB and LRYGB groups were comparable for all analyzed variables, except that the preoperative weight and BMI were greater in the LRYGB group. No differences in weight or BMI were found at conception or after pregnancy. No difference was found between the 2 groups in terms of obstetric complications or neonatal outcomes. A high frequency of cesarean deliveries was necessary in both groups.
  
  
  CONCLUSIONS
  The results of the present study have shown that no significant difference exists in the obstetric and birth outcomes between women who have undergone LRYGB and those who have undergone LAGB.
