Short and long-term results of air-filled intragastric balloon in obese patients

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.
