Doctors are currently working on a cutting-edge type of obesity surgery that does not require any cuts in the abdomen. It is performed by feeding a tube about the thickness of a garden hose down the throat in order to snap staples into the stomach.
This preliminary, scar-free method fabricates a more slender passage that slows the movement of food as it goes from the top of the stomach to the bottom part of the stomach. This helps patients feel fuller faster, so they end up eating less.
Doctors are happy with the encouraging experimental results so far from 200 patients in the U.S. and 100 in Europe.
Dr. Gregg Nishi, a Cedars-Sinai Medical Center surgeon in Los Angeles, said that an average of around 45 percent body weight has been lost from obese European patients, after only 18 months. He talked about the studies this week during a conference for digestive disease specialists in Chicago. Currently the procedure is only being performed in studies. The enrollment for this new study has just recently ended.
Nishi indicated that the results up to this point are moderately better than the usual stomach stapling method. One of the risks is perforation of the esophagus, which actually occurred in a patient at one of the centers. Apart from that, he said that there are no other complications.
An administrative coordinator at Cedars-Sinai, Lillian Gomez, was one of the first Americans to have the new scar-less surgery last year. She was going to have the surgery that is usually performed, until she learned that doctors at her hospital were experimenting with the innovative technique.
Gomez had her surgery in August and has lost 40 pounds since then, going from a size 22 to a size 16. She is still obese according to body mass index standards, but she has reduced the size of her meals by more than half and still feels full. She is confident that she will continue to lose weight.
This new scar-free surgery is part of a medical progression to conduct surgery through body openings instead of making incisions. The goal is to reduce recovery time and decrease the risks for infection.
Initially, Gomez had thought about getting a gastric bypass operation, which is a more complex and invasive procedure that raises the risk for malnutrition, because it repositions where the stomach attaches to the intestines. There is another popular weight-loss surgery option in which an adjustable band is applied to the top part of the stomach to help the patient feel fuller faster.
Although surgery is usually a last resort option for obese patients, more than 200,000 Americans are predicted to undergo the conventional types of obese surgery this year, according to the American Society for Metabolic & Bariatric Surgery.
