endoluminal sleeve

endoluminal sleeve

,

ELS.

A flexible tube attached to the inside of the duodenum to block the absorption of nutrients by the proximal small intestine. It prevents the modification of consumed foods by bile and pancreatic enzymes (a process that normally takes place in the duodenum) and delivers unprocessed nutrients to the jejunum. It is used in bariatric surgery.

The researchers implanted the device, called an endoluminal sleeve, in eight rats that had been brought up on a high-fat diet, resulting in obesity and mild diabetes.
With a view to determining whether the endoluminal sleeve could prevent obesity, the research team implanted the device in rats genetically prone to rapid weight gain but lean since they had been brought up on a low-fat diet.
While both groups gained weight during the postsurgical period, most of the rats receiving the endoluminal sleeve ate less than the control rats and weighed 12 percent less four weeks after the procedure.
