Overview of bariatric and metabolic endoscopy interventions.

The rise of endoscopic techniques allowing weight loss offers an attractive alternative to surgical interventions in Western countries where the obesity epidemic has risen dramatically. Endoscopists are well positioned to manage obesity given their broad-based medical knowledge, understanding of gastrointestinal physiology, and training in endoscopic technique. The field of bariatric and metabolic endoscopy has permitted the development of several efficacious and safe technologies. This review focuses on techniques and devices used for endoscopic management of obesity, as well as the fundamental justifications to offer those therapies to obese patients.
