      Background and aims: Obesity with type-2 diabetes is a global challenge. Lifestyle interventions have limited effect for most patients. Bariatric surgery is highly effective, but resource-demanding, invasive and associated with serious complications. Recently, a new intragastric balloon was introduced, not requiring endoscopy for placement or removal (Elipse™, Allurion Inc., Natick, MA). The balloon ...

We aimed to compare the effect of bariatric surgery and comprehensive lifestyle intervention on type 2 diabetes and obesityrelated cardiovascular risk factors. Design: One-year controlled clinical trial (ClinicalTrials.gov identifier NCT00273104). Methods: Morbidly obese subjects (19–66 years, mean (S.D.) body mass ...

      Background and aim - Bariatric surgery is the most effective treatment for obesity but is invasive and associated with serious complications. Endoscopic sleeve gastroplasty (ESG) is a less invasive weight loss procedure to reduce the stomach volume by full-thickness sutures. ESG has been adopted in many countries, but implementation at Scandinavian centres has not yet been documented. We performed ...
