[Implementation of endoscopic sleeve gastroplasty in Sweden]

Obesity is a growing health problem and challenge to the health care systems in the western world. Available treatment is limited to lifestyle modifications, cognitive therapy, drugs and bariatric surgery. On one hand, lifestyle changes and pharmacological treatment have very limited long-term effects on obesity. On the other hand, bariatric surgery is effective to maintain long-term weigh reduction but is associated with complications and reaches less than 2 % of patients with indication for surgery. Thus, there is a gap in the management of patients with obesity, and endoscopic bariatric therapies might fill that gap by providing effective, repeatable and reversible alternatives for selected patients with obesity. This article introduces endoscopic methods to achieve weight loss with special focus on endoscopic sleeve gastroplasty (ESG). Data in the literature demonstrates that ESG is effective in reducing total and excessive body weight up to two years after the procedure as well as reducing obesity-related co-morbidity. The challenge is that ESG requires advanced endoscopic skills and is not yet available at many centres. A structured training program is needed to disseminate ESG and offer selected patients with obesity an alternative to bariatric surgery in Europe.
