Abstract:

Obesity has emerged as a major global public health challenge, accompanied by a significant rise in obesity-related comorbidities. Although conventional bariatric surgery achieves reliable outcomes, its invasiveness, potential risks, and irreversible anatomical alterations have limited widespread application. With the rapid advancement of digestive endoscopy, endoscopic bariatric therapies are increasingly recognized as minimally invasive alternatives that combine safety and efficacy. This review summarized the current progress and clinical applications of various endoscopic bariatric techniques, including intragastric balloons, endoscopic sleeve gastroplasty, and primary obesity surgery endoluminal procedures that reduced gastric volume via space-occupying, or suture and anastomosis technology achieved by oral devices. In addition, aspiration therapy, which removes gastric contents, and innovative methods such as duodenal-jejunal bypass liners and duodenal mucosal resurfacing that mimic surgical bypass or induce mucosal remodeling were discussed. Endoscopic bariatric technologies showed promising prospects and were expected to become an important component of comprehensive obesity management.
