And patients can recover in just a couple days versus two weeks or more for gastric bypass surgery.
But the clinical trial's results aren't quite as good as gastric bypass patients'. They had about the same result as the gastric band without the cutting.
One thing no one knows is exactly how much this surgery would cost. Doctors assume the maker of the device used will probably charge about what it costs now for a gastric band procedure, which is about $13,000 to $20,000.
Eventually it would probably be covered by insurance and the hope is to make it an outpatient procedure.
Doctors are excited to see how these patients do after a couple of years since it usually takes longer than a year after a stomach stapling to lose all the weight patient's are going to lose.
Aside from being less invasive, Phillips said that this technique has the added possibility of helping those who are not yet morbidly obese, but who are on their way. These people would not have been able to opt for full-blown surgery, as the benefits that they would reap would not be enough to justify the downsides of surgery.
"This could be available to a huge selection of people earlier, while they are en route to morbid obesity," he said.
As for Gomez-Guerrero, she hopes to slim down to about 160 pounds and be a size nine or 10 because "it's much more comfortable than being a size 20, 24."
Thanks to the surgery Gomez-Guerrero has a healthier outlook on life and wants to celebrate it by doing something she could have never done before.
"I started running and I think I would like to do a marathon," she said. "I truly want to do it."
