Deflation of gastric band balloon in pregnancy for improving outcomes

In line with the rise in the prevalence of obesity, an increasing number of women of childbearing age are undergoing laparoscopic adjustable gastric banding (LAGB), resulting in an increasing number of pregnancies with a band in place. Currently, there is no consensus on optimal band management in pregnancy. Some clinicians advocate leaving the band balloon inflated to reduce gestational weight gain and associated adverse perinatal outcomes. However, there are concerns that maintaining balloon inflation during pregnancy might increase the risk of band complications and adversely affect fetal development and/or growth as a result of reduced nutritional intake.

To compare maternal and perinatal outcomes for elective gastric band balloon deflation versus intention to maintain balloon inflation during pregnancy.

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 September 2012) and the Web of Science database (1940 to September 2012).

Randomised-controlled trials comparing elective deflation of the gastric band balloon with intention to maintain balloon inflation in pregnant women who have undergone LAGB.

Two review authors independently assessed studies for inclusion.

No studies met the criteria for inclusion in the review.

To date no randomised controlled trials exist that compare elective deflation of the gastric band balloon in pregnancy versus intention to maintain balloon inflation. Further research is needed to define the optimum management of the gastric band balloon in pregnancy.
