[Endoscopic treatment of obesity and complications following bariatric surgery]

The prevalence of obesity in the population has been increasing for many years. Due to associated comorbidities the treatment of obesity is becoming more important. Conservative treatment alone is often unsuccessful, particularly in cases of severe obesity. In these cases, multimodal therapy in specialized treatment units is warranted. Between conservative treatment and bariatric surgery, interventional endoscopic treatment options also play an increasing role. Nowadays, implantation of gastric balloons and duodenojejunal bypass liners (EndoBarrier) are the most often used endoscopic options. A further typical application of endoscopy in the treatment of obesity is the management of complications after bariatric surgery, such as stenosis and insufficiency. This article gives an overview on the currently available endoscopic options associated with treatment of obesity.
