Pregnancy after adjustable gastric banding

Area of Science:

• Bariatric Surgery
• Reproductive Health
• Maternal-Fetal Medicine

Background:

• Obesity is a significant risk factor for pregnancy complications.
• Adjustable gastric banding is a surgical treatment for obesity.
• Understanding pregnancy outcomes after gastric banding is crucial for patient counseling.

Purpose of the Study:

• To determine the outcomes of pregnancies in obese women who underwent surgical placement of an adjustable gastric band.
• To evaluate fetal and neonatal outcomes in this patient population.

Main Methods:

• Two clinical trials involving 359 obese women of reproductive potential were analyzed.
• Data on 23 pregnancies resulting from conception in 20 women were collected.
• Information was gathered via medical records and direct patient contact.

Main Results:

• Eighteen of 23 pregnancies resulted in full-term deliveries, with 14 vaginal and 4 cesarean births.
• Mean birth weight was 3676 g; five women experienced weight loss during pregnancy without adverse effects.
• Gastric band adjustments for nausea/vomiting were sometimes associated with excessive weight gain.

Conclusions:

• Pregnancies following adjustable gastric banding in morbidly obese women were largely uncomplicated.
• Band adjustments for symptoms can impact weight management; prophylactic adjustments may lead to excessive gain.
• Effective contraception counseling is vital for obese women undergoing gastric banding due to potential unexpected pregnancies.
