Intragastric Balloons for Overweight Populations-1 Year Post Removal

Abstract

Background: Endoscopic balloons have been used for years to treat obese seeking weight loss. This study evaluated the safety and effectiveness of our lifestyle modification program.

Methods: Retrospective analysis of prospectively collected data from patients who underwent End-ball® (Endalis) intragastric balloon insertion with a multidisciplinary follow-up program. Demographic data, weight loss complications, and satisfaction rates were assessed.

Results: In total, 114 overweight/obese individuals from July 2012 to December 2015 were included. Mean age 36.5 years (72% females). Initial body mass index (BMI) was 33.5 kg/m². Twelve early removals (10.52%) due to intolerance (n = 7), dissatisfaction (n = 4), and esophagitis (n = 1); 102 patients completed the program. BMI reduction ranged 5.5-6.4 at balloon removal and 4.1 1-year post removal. Average excess BMI loss (EBMIL) was 46-48% at balloon removal and 39.1% after 1 year; 75% of participants maintained > 60% of their weight loss 1 year after removal. EBMIL was 17 and 48% when initial BMI > 35 and ≤ 35 kg/m², respectively. At removal, 80% of patients were satisfied with the process.

Conclusion: The End-ball® program resulted in significant weight loss that continued for 1 year after balloon removal, with minimal complications. When treating overweight/obese populations, the main principles of the balloon insertion process should be no complications, high safety, and significant effectiveness. The process was most beneficial in the overweight and class I obese populations since average BMI was 33 and the class II obese had less weight loss and can possibly prevent future bariatric surgery.
