New research from King’s College London has found that a newly tested medical device, called Sleeveballoon, mimics the effects of traditional bariatric surgery in rodents and produces impressive results on body weight, fatty liver and diabetes control.
Sleeveballoon is a device that combines a balloon with a connected sleeve, which covers the initial parts of the small intestine. It is inserted into the stomach and bowel during minimally invasive surgery under general anesthetic.
How was the Study Conducted?
In the study, researchers compared the effects of the Sleeveballoon and traditional bariatric surgery on 30 rodents fed with a high-fat diet, achieving very similar results.
Results were also compared to sham-operated rats, with the new device reducing food intake by 60% and resulting in a 57% reduction in fat mass.
The effect on diabetes was similarly impressive with blood glucose levels dropping by 65%.
“Gastric bypass surgery is a highly effective treatment of obesity and Type 2 diabetes. However, very few eligible patients, only around 1%, are offered surgery and some also prefer less invasive approaches,” said lead author, professor Geltrude Mingrone from King’s College London.
Mingrone’s team found that the metabolic effects of the Sleeveballoon device are similar to those of the gastric bypass but have distinct advantages over the traditional method.
In both, insulin sensitivity and heart function improved. However, while gastric bypass causes a rapid rise in post food blood glucose levels which can cause hypoglycemia, the Sleeveballoon induces a slowing down of digestion which has a steadying effect on blood sugar levels.
“This helps control appetite and hunger, keeping the person fuller for longer and substantially reduces weight,” Mingrone said.
The device should be removed after 6 to 12 months, and the team is eager to test the device in say more research is needed to manage this process and avoid reversal of the positive effects on obesity and diabetes.
“About two billion adults, or 30% of the world’s population, live with overweight or obesity according to the World Health Organization,” points out Mingrone.
“At present, 500 million people suffer from Type 2 diabetes and about two billion people have fatty liver disease. We hope that our discovery will be tested in humans soon and revolutionize the way we tackle this epidemic,” she added.
The research has been published in EBioMedicine.
