Laparoscopic Adjustable Gastric Banding (LAGB) is a safe and effective treatment for obesity. A strong evidence links weight loss with improved fertility outcomes and reduced gestational complications in subsequent pregnancies. Our aim is to describe the impact of LAGB on maternal and neonatal outcomes.


Data were collected retrospectively from the database of our University Center for the Multicentric Treatment of Severe Obesity. From January 2006 to December 2011, 438 patients underwent LAGB. Of these, 140 women of reproductive age (18-46 years old) were included in our study. The following parameters were registered during follow-up: number of pregnancies, delivery and miscarriage, time from LAGB to pregnancy, band adjustments, weight gain during pregnancy, gestational and obstetrical complications (gestational diabetes mellitus, hypertensive disorders, prolonged labor), mode of delivery, neonatal birth weight and complications (low birth weight, IUGR, prematurity, macrosomy).


We registered 26 pregnancies with a total of 22 babies born and 4 miscarriages. The mean time from LAGB to pregnancy was 15.8 months. Band adjustments were performed in 100% of patients during the first trimester; the average weight gain at the end of pregnancy was 14.66 kg. None presented gestational or obstetrical complications. One patient presented band slippage, which required surgery, and one patient presented iron-deficiency anemia. 100% of deliveries were by cesarean section. No perinatal complications or malformations were recorded, and the average baby weight was 3027 g.


LAGB is a safe procedure, well tolerated during pregnancy and without negative implications on both the mother and the baby. According to our experience and recent studies, band loosening should be reserved to symptomatic patients to avoid unhealthy weight gain.
