During the treatment, which is intended for mildly to moderately obese people, an interventional radiologist inserts a needle through a patient's back. With live images from a CT scan, they are able to guide the instrument to the nerve, located at the base of the esophagus, to emit argon gas to numb it.
They tested their methods on 10 subjects with a body mass index between 30 and 37, and examined them for 90 days. During the follow-up period, they found that all the subjects had a decreased appetite. Furthermore, they had an overall average body weight loss of 3.6 percent and an average body mass index decline of 14 percent.
Now they are recruiting more individuals to undergo the process for a larger clinical trial.
“We are trying to help people succeed with their own attempts to lose weight,” Prologo said.
