Abstract

BACKGROUND:

Laparoscopic adjustable gastric banding (LAGB) is a proven method for weight reduction. Less is known about pregnancies in patients after LAGB.

METHODS:

Information was gathered, through database and survey, on women who underwent LAGB at NYU Medical Center between 2001 and 2008 then became pregnant.

RESULTS:

Pregnancy occurred in 133 women, resulting in 112 babies, including six sets of twins. The average pre-pregnancy body mass index (BMI) was 32.7. Average weight gain was 11.5 kg, but was higher for those with pre-pregnancy BMI <30.0 compared to BMI >30.0 (16.4 vs 8.6 kg). Of singleton pregnancies, 89% were carried to full term, with cesarean section in 45%. Those with pre-pregnancy BMI <30.0 had a lower rate of cesarean section (35.71%), but it was not statistically significant (p = 0.55). Average birth weight was 3,268.6 g. Eight percent of babies from singleton pregnancies were low birth weight (<2,500 g), and seven percent were high birth weight (>4,000 g). Average Apgar scores at 1 and 5 min were 8.89 and 9.17. Four percent of patients developed gestational diabetes, and 5% developed pre-eclampsia. Band adjustments were performed in 71% of patients. Weight gain was higher in those who had their bands loosened in the first trimester (p = 0.063). Three patients had intrapartum band slips; one required surgery during pregnancy.

CONCLUSIONS:

LAGB is tolerable in pregnancy with rare intrapartum band slips. Weight gain is less in those with higher pre-pregnancy BMI and those who had their bands filled or not adjusted. Babies born to these mothers are as healthy as the general population.
