ABSTRACT
INTRODUCTION: Obesity is an expanding public health problem, resulting in more than half a billion adults worldwide. Intragastric balloon (IGB) placement is a weight loss alternative for obese patients with an inadequate weight loss response to diet and exercise. The aim of this study is to examine the efficacy and safety of the single-chamber fluid-filled IGB for weight loss and compare its results across different age groups. METHODS: We performed a database review of 239 consecutive patients from two outpatient GI clinics who underwent placement of an IGB. Our final analysis composed of 239 IGB placements in 232 patients (mean age, 44.5 ± 10.3 years; 67% female; baseline BMI 42.0 ± 9.0). Efficacy outcomes included the percentage of the total (%TWL) and excess weight loss (%EWL). Safety outcomes were measured as the number of patients who required early IGB removal (before 6 months). RESULTS: %TWL at 3 months was 10.1% and 14.4% at 6 months. Overall, 92%, 74%, and 47% of patients lost 5%, 10%, and 15% of total weight at 6 months, respectively. %EWL was 22.1% and 30.7% at 3 and 6 months post-IGB placement, respectively. The balloon was safely removed at six months after placement in most patients, whereas in 13.0% of cases early removal was performed at an average of 12.0 weeks after placement (range, 2 days-23 weeks). CONCLUSION: The use of a single-chamber fluid-filled IGB is successful in inducing a significant amount of weight loss in almost three-fourths of patients six months after its placement. This beneficial effect is seen across different BMI ranges and age groups at a similar level. IGBs should be considered an effective and safe alternative for obese patients who fail lifestyle interventions and conservative measures, fulfilling the unmet needs of many who are unwilling or unable to undergo bariatric surgery.
