Duodenal-jejunal bypass liner
From Wikipedia, the free encyclopedia
A duodenal-jejunal bypass liner, commonly called an EndoBarrier, is an implantable medical device in the form of a thin flexible 60 cm-long tube that creates a physical barrier between ingested food and the duodenum/proximal jejunum. The duodenal-jejunal bypass liner prevents the interaction of food with enzymes and hormones in the proximal intestine to treat type 2 diabetes and obesity. The duodenal-jejunal bypass liner is delivered endoscopically and has been tested on the morbidly obese (those with a body mass index [BMI] greater than 40) as well as obese patients with a BMI less than 40, particularly those with difficult-to-manage type 2 diabetes. Despite a handful of serious adverse events such as gastrointestinal bleeding, abdominal pain, and device migration — all resolved with device removal — initial clinical trials have produced promising results in the treatment's ability to improve weight loss and glucose homeostasis outcomes.[1][2]
