Background: Intragastric balloons (IGBs) have been used to bridge the obesity treatment gap with the benefits of being minimally invasive but still required endoscopy. The Elipse IGB is a swallowable balloon that is spontaneously excreted at ∼16 weeks. However, studies are limited by small sample sizes. The authors aim to assess clinically relevant endpoints, namely weight loss outcomes, metabolic profile, balloon tolerability, and adverse events. Methods: A literature search was performed from several databases from inception to July 2020. The pooled means and proportions of our data were analyzed using a random effects model. Results: Seven studies involving 2152 patients met our eligibility criteria and were included. The mean baseline body mass index ranged from 32.1 to 38.6. The pooled mean difference (MD) in body mass index was 0.88 [confidence interval (CI): 0.58-1.18, I2=98%]. Total body weight loss was 12% (CI: 10.1-14.3, I2=94%) and excess body weight loss was 49.1% (CI: 30.6-67.5, I2=97%). The MD in waist circumference was 0.89 (CI: 0.72-1.05, I2=53%). MD in triglyceride level was 0.66 (CI: 0.21-1.1, I2=96%). Pooled early deflation rate was 1.8% (CI: 0.6-5.1, I2=74%). Our study also showed that the Elipse balloon was associated with less adverse events when compared with other IGBs. Conclusions: This meta-analysis demonstrates that the Elipse intragastric balloon is a safe, effective, and tolerable device for weight loss and obesity with a minimal side effect profile.
