Introduction: The aim of this study was to analyze the effect
of the Heliosphere® BAG in terms of early weight reduction and
trend of weight at a distance of 18 months after removal.
Methods: Between November 2006 and November 2010,
45 patients underwent the placement of endoscopic intragastric
air-filled balloon. All patients were selected by a multidisciplinary
team according to international guidelines. At 18 months after
removal, weight control was performed by telephone questionnaire.
Results: 32 patients completed the 6-month stay of the balloon
and showed a mean weight reduction of 12 Kg with a reduction
in BMI of about 5 points. 15 were contacted by telephone 18
months after device removal: the mean basal BMI was 40.62 kg/
m2 and mean weight was 113.37 Kg. The mean BMI at the end of
6 months was 35.75 kg/m2 and the mean weight was 99.75 kg; the
BMI at 18 months after removal was 37.28 kg/m2 and the mean
weight was 103.56 kg. No technical problems were recorded at balloon
insertion and removal.
Conclusion: Heliosphere® BAG showed good weight loss in
the short term. In patients with 18 months follow-up, we observed
a minimal weight increase (a mean of 4 kg). This device, within
a few months after removal, may reduce surgical and anesthesiological
risks for bariatric or other elective surgery. Moreover
Heliosphere® BAG with dietary support can offer a potential benefit
in the long-term treatment of obesity.
