Intragastric Balloons for Overweight Populations-1 Year Post Removal

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.

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.

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.

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.
