ECO 2023 181 Data of patients treated with a combination of the Allurion balloon program and Saxenda® retrospectively analyzed from 3 international multidisciplinary obesity centers. Treatment started with the Allurion balloon, and later Saxenda® was added. All patients were followed for at least 6 months. 2331 total patients with a BMI ≥ 27kg/m 2 received the swallowable IGB programme. Of these 181 (7.7%) received this combination therapy 145F / 36M Mean baseline weight: 94.8 ± 21kg Mean baseline BMI: 33.7 ± 6.2kg/m 2 After 4 months of balloon treatment, WL, %TBWL, %EWL and BMIL were 13.1 ± 7kg, 13.9 ± 7.7%, 74.3 ± 57.1% and 4.5 ± 1.4kg/m2 respectively. Saxenda® therapy added between week 4-16 after balloon placement. Average duration of drug treatment 4.1 ± 2.2 months. Total length of combined treatment was: 7.76 ± 2.1 months Main reasons for adding Saxenda®: unsatisfactory weight loss 52.6%, reduction of balloon induced satiety 29%, to further boost weight loss in successful patients 16%. At the end of the treatment with Saxenda® WL, %TBWL, %EWL and BMIL were 18.1 ± 12.1 kg, 18.7 ± 12%, 99.4 ± 84.9% and 6.4 ± 5.9kg/m 2 respectively. The Allurion balloon program delivers excellent weight loss in patients with overweight and obesity. In case of suboptimal adherence with the program and for patients that are aiming to further boost the results of treatment, the combination with the GLP1 agonist, Saxenda®, is safe and effective in improving results.

Reported IGB 'shifted mindset', including control of overeating and increased self- efficacy for behavior change. Data suggests variation in perceived behavioral control amongst patients – for some awareness and self-efficacy was low Enhancing self-efficacy and perceived behavioral control appears necessary to impact outcomes in IGB patients. Further research will explore this relationship and identify methods to support this cognitive shift more universally.

No complications The main finding of the present study was a significant BMI reduction and Metabolic syndrome remission rate within 4 months of treatment instead of 6 months, as happens in other balloons Genco, A., Ernesti, I., Ienca, R., Casella, G., Mariani, S., Francomano, D., Soricelli, E., Lorenzo, M., & Monti, M.

No complication during balloon passage. 37 normal stool excretion, 1 endoscopic removal. The results of this study on 38 consecutive patients demonstrate that the Allurion ™ Balloon is safe, effective, and very well accepted by patients.

No SAEs, all AEs were expected and normal These results demonstrate clinically significant weight loss with the Allurion Program, the first procedureless gastric balloon. The weight loss was similar to that seen in previous studies of endoscopically placed balloons. In addition, Allurion therapy led to improvements in waist circumference, several metabolic parameters, and overall quality of life. Raftopoulos, I., & Giannakou, A. (2017).

V. (2021). Cost-effectiveness of procedure- less intragastric balloon therapy as substitute or complement to bariatric surgery. PloS one, 16(7), e0254063. https://doi.org/10.1371/journal.pone .0254063 NA Practice economics Cost effectiveness comparison of procedureless intragastric balloons (PIGB), gastric bypass/sleeve gastrectomy, Gastric balloon as a bridge to gastric bypass/sleeve gastrectomy and no treatment. NA Gastric balloon as a bridge to bariatric surgery is less costly and more effective than bariatric surgery alone as it helps to achieve a lower post-operative BMI. Of the six strategies, PIGB as a bridge to sleeve gastrectomy is the most cost-effective. While PIGB alone is not cost- effective compared with bariatric surgery, it is cost-effective compared with no treatment. PIGB can yield cost savings and improve health outcomes if used as a bridge to bariatric surgery and is cost-effective as a stand-alone treatment for patients lacking access or unwilling to undergo surgery
