Emerging technology: endoluminal treatment of obesity.
BACKGROUND
Bariatric surgery remains the most effective treatment for the management of obesity. Endoluminal interventions offer the potential for an ambulatory weight loss procedure that may be safer and more cost-effective compared with current laparoscopic approaches.


OBJECTIVE
We review the currently available endoluminal techniques for obesity that have been presented or discussed in public forums and meetings, focusing on those with published trials.


METHODS
Literature review.


RESULTS
Human trials of endoluminal treatments of obesity are primarily limited to restrictive interventions, including intragastric balloons, transoral gastroplasty, and endoluminal vertical gastroplasty. Currently, the duodenojejunal bypass sleeve is the only endoluminal device that has been studied in humans that promotes weight loss through malabsorption. Early results of these technologies are promising, but long-term data are lacking.


CONCLUSIONS
Endoluminal treatments for obesity have promise, and recent technological advances have been astounding. However, these interventions will need to be held to the same standards of current operative techniques. Each device will need to be scrutinized within clinical trials to determine its safety, efficacy, and durability.
