Introduction: Morbid obesity, which affects over 15 million people, is a major health concern for the United States. Surgical therapy is the most effective means of weight loss. A less costly, truly minimally invasive procedure would be a valuable adjunct in the treatment of morbid obesity.

Methods: The EndoBarrierTM (GI Dynamics, Inc) duodenal-jejunal bypass sleeve is a totally endoscopic delivered device designed to produce weight loss by altering metabolic pathways and restricting absorption. It is comprised of a selfexpanding nitinol anchor, an impermeable, fluoropolymer sleeve, and two retrieval drawstrings. The coaxial, catheter-based delivery system is introduced into the duodenal bulb over a guide wire and deployed utilizing fluoroscopy. Proximally placed barbs penetrate into the muscularis propria and allow for anchor stabilization within the proximal jejunum. Upon deployment, a bolus of dilute contrast confirms the device is in the correct position. A duodenal-jejunal bypass is created as chyme passes through the inside of the impermeable EndobarrierTM, while bile and pancreatic enzymes pass outside the sleeve and mix with the chyme at its distal end.

Conclusion: This video describes the first placement and retrieval of a duodenal-jejunal bypass sleeve within the United States. The EndobarrierTM may offer the morbidly obese population a new totally endoscopic method of weight loss that requires no operative intervention, minimizes cost, and speeds post-procedure recovery. A randomized, single-blind, placebo-controlled, FDA trial evaluating the deployment, efficacy, and removal of the EndoBarrierTM is underway.
