OBJECTIVE: This prospective study sought to examine the outcomes of 79 consecutive first pregnancies (> 20 weeks of gestation) in women following laparoscopic adjustable gastric banding (LAGB) for severe obesity.
METHODS: The 79 women are from a cohort of 1,382 consecutive patients. The prospectively collected data from 79 first pregnancies has been compared with these patients' previous penultimate pregnancies (n= 40), obstetric histories from matched severely obese subjects (n = 79), and community outcomes.
RESULTS: The mean maternal weight gain was 9.6 ± 9.0 kg, compared with 14.4 ± 9.7 kg for the 40 penultimate pregnancies of women in this group (P < .001). There was no difference in birth weights: 3,397 g compared with 3,350 g for preband pregnancies, and these were consistent with normal community birth weights. The incidence of pregnancy-induced hypertension (10%) and gestational diabetes (6.3%) were comparable with community levels (12% and 5.5%) and lower than the obese cohort (38% and 19%) and these patients' penultimate pregnancies (45% and 15%). Monitoring and, if necessary, band adjustments during pregnancy provided more favorable maternal weight outcomes (P = .027). Neonatal outcomes, including stillbirths, preterm deliveries, low birth weight, and high birth weight, were consistent with community values. One woman developed anemia during pregnancy.
CONCLUSION: Pregnancy outcomes after LAGB are consistent with general community outcomes rather than outcomes from severely obese women. The adjustability of the LAGB assists in achieving these outcomes. Adjustability is appealing because it allows adaptation to the altered requirements of pregnancy.
