A new type of obesity surgery currently being tested is incision-free, entering through the mouth and throat to snap staples in the patient’s stomach.

The scar-free procedure, in which a tube is inserted through the mouth, is designed to help patients feel full more quickly.

Doctors say the preliminary results from patients in the U.S. and Europe look promising.

Following the procedure, obese European patients have lost an average of 45 percent of their body weight in 18 months, according to BlackAmericaWeb.com. If the research continues to go as planned, the device’s developers intend to seek federal approval.

So far, surgeons believe the results are slightly better than typical results from traditional stomach stapling.

“ is still very new, so long term results are as yet unavailable,” Dr. Elliot Goodman of the Beth Israel Medical Center wrote in a posting on medhelp.org. “However, if the promise of the incision free surgical procedure of reduced complications and faster recovery times holds true, incision free surgery could significantly expand the number of patients who are able to undergo weight loss surgery.”

Many patients have viewed the procedure as a better option over conventional stomach stapling.

“When I found out it was going to be oral, through your mouth, I was like, ‘Wow, that’s kind of different, Liliana Gomez, one of the first Americans to have the surgery, told BlackAmericaWeb.com.

Following her procedure in August, Gomez has shed 40 pounds and went from a size 22 to 16.

According to medical experts, surgery should be the last resort in weight-loss, but the demand still remains high. The American Society for Metabolic & Bariatric Surgery predicts that over 200,000 Americans will have traditional obesity surgeries this year.
