The use of intragastric balloons (IGB) for the treatment of obesity has been increasing significantly, with data confirming its effectiveness with low complication rates. Adjustable balloons are not widely available for use in all countries, including the USA. In this video, we demonstrate a unique technique in which a conventional nonadjustable balloon is modified to an adjustable balloon to improve weight loss.


A 35-year-old woman with a BMI of 36.1 kg/m2 (84.4 kg) who had failed prior medical therapy for obesity presented for IGB placement. After discussion with the patient, including risks and benefits, a conventional IGB modified to a novel adjustable IGB was placed.


In this primary experience, we describe the use of a conventional IGB modified to an adjustable balloon. First, during balloon placement, an initial 500 ml of saline was instilled. At one-month follow-up, the patient only experienced 3.67%TBWL; thus, the balloon was adjusted with the addition of 160 ml of saline through the newly created modification catheter. At a 2-month follow-up, a second adjustment was performed with the addition of 180 ml, for a total of 840 ml. At 4 months, patient experienced 10% TBWL and decreased in BMI by 3.6 kg/m2. No adverse events were reported.


The transformation of a nonadjustable balloon into an adjustable balloon is feasible and effective in weight loss. This technique may be an alternative in cases where adjustable balloon is not available. Further studies are warranted to confirm the safety and efficacy of this novel device.
