RESUMO
BACKGROUND: Obesity is the most common chronic disease in the United States today. Additional therapies are needed to improve obesity treatment. OBJECTIVE: A swallowable, gas-filled intragastric balloon system was approved for the treatment of obesity by Food and Drug Administration in September 2016 and commercialization started January 2017. A registry was made available to physicians to capture evidence of safety and effectiveness with use. SETTING: United States private clinics, surgery centers, and hospitals. METHODS: This study is a retrospective analysis of a prospective registry of patients with body mass index (BMI) ≥25 kg/m2 that initiated therapy in the first year. Data on demographics, procedural timing, weight loss, adverse events, and device deficiencies were captured. RESULTS: The final analysis comprised 1343 patients across 108 treating physicians (mean age 45.7 ± 10.8 yr, 78.6% female, baseline BMI of 35.4 ± 5.4 kg/m2). Nonserious and serious adverse events were reported in 14.2% and .15% of patients, respectively. There were 7 balloon deflations, none caused obstruction. Weight loss in the indicated use (BMI 30-40 kg/m2) was 9.7 ± 6.1 kg and 10.0 ± 6.1% total body weight loss (TBWL). Weight loss in other BMI categories was 8.2 ± 5.6 kg or 10.3 ± 7.0% total body weight loss for BMI 25 to 29.9 kg/m2 and 11.6 ± 7.8 kg or percent total body weight loss 9.3 ± 6.0 for BMI >40 kg/m2. CONCLUSIONS: This swallowable gas-filled intragastric balloon system is safe and effective at inducing weight loss and offers physicians another tool for patients whose obesity has been resistant to noninvasive treatments.
