Purpose of review Endoscopic bariatric therapy (EBT) is a rapidly developing area that has now seen FDA approval of six endoscopic bariatric devices and procedures and there are a number of other novel EBTs progressing through various stages of development with newly published findings. This paper aims to assist readers in either selecting an appropriate therapy for their patient or deciding to incorporate these therapies into their practice. This paper provides an updated review of the available data on EBTs, both FDA approved and not, with a particular focus on effectiveness and safety, as well as guidance for discussing with your patient the decision to use endoscopic therapies. Findings The authors of a large meta-analysis of Orbera concluded its ideal balloon volume to be 600-650 mL. AspireAssist has had favorable effectiveness and safety data published in a large RCT. A large study of endoscopic sleeve gastroplasty has published findings at up to 24 months showing promising durability. Elipse, a swallowed intragastric balloon not requiring endoscopy for either insertion or removal, has had early favorable results published. A magnet-based system for creation of a gastrojejunostomy has published favorable findings from its pilot study. Summary EBTs are safe and effective therapies for weight loss when used in conjunction with lifestyle changes and fill an important gap in the management of obesity. There are now six FDA-approved EBTs available and several more in ongoing trials with favorable early findings. More study is needed to understand the role of EBTs used in combination or in sequence with medications and bariatric surgery.
