European doctors have developed a new procedure meant to combat obesity -- inserting a balloon into the stomach.
In the Stomach for Half a Year
A round silicon balloon, about half a liter in volume, is inserted down the patient's throat and filled with saline solution. It remains there for six months, after which it is deflated and removed.
Being Tested for U.S. Use
Initial tests for use of the balloon technique in the United States are being conducted in Louisville, Kentucky, but the procedure has not yet been approved for widespread use.
