Background: Bariatric surgery has been shown to be the most efficient modality to treat morbid obesity. Unlike morbid obese, the overweight and obese population are more prevalent with limited surgical options. Gastric balloon has emerged to tackle the gap in the options for the overweight and obese population. The new swallowable both fluid filled and air filled balloons are newly introduce in the treatment options.The Obalon needed endoscopic extraction at three months while the Ellipse ballon required no extraction since it will empty the fluid after four months from insertion. We present our results for the weight loss for both fluid filled (Ellipse, Allurion Technologies Inc) 550 ml balloon for four month and air filled Obalon (Obalon Therapeutics, Inc) two balloons of 250 ml for three weeks.
Objectives: To compare the weight loss of fluid filled Ellipse balloon for four months with two air filled obalon at time of extraction at three months.
Methods: A retrospective study of 75 patients (34 Ellipse and 41 Obalon) who presented to our clinic seeking management for obesity. Data were collected in a period of 24 months and consent forms were obtained. Obalon final weight obtained at 3 months extraction visit and Ellipse patients’ weight obtained at 4 months visit at the clinic.
Results: Patients were studied over a period of 24 months. There were no statistical differences between the Ellipse and Obalon patients in term of Age, Gender and initial BMI. The % excess body weight loss (%EBWL) for the Ellipse and Obalon were 49.3% and 31.5% respectively (p<0.001). The % total body weight loss (%TBWL) was 9.6% and 7.1% respectively (p<0.001).
Conclusion: The fluid filled Ellipse balloon showed statistically more weight loss at the end of the treatment in comparison with the air filled( two balloons) Obalon. The study will continue to reach a larger sample and also to compare the newly introduced three balloons Obalon.
