New methods offer alternatives for patients undergoing obesi...( a small silicone band placed around th...),Health

a small silicone band placed around the upper section of the stomach; Vertical Gastrectomy (VG), during which 90-95 percent of the stomach is removed, leaving a small, thin, tube-like stomach approximately two ounces in size; Roux-en-Y Gastric Bypass (RGB), which restricts food intake by separating a small portion of the stomach with a line of staples; and Duodenal Switch (DS), which removes a large portion of the stomach to lower the capacity to store food and rearranges the small intestine to inhibit the absorption of calories.

More than half of the participants received the RGB operation, while 22, 19 and 8 percent received the BAND, VG and DS operations, respectively. The operation times were shortest for the BAND and VG procedures (both under two hours), versus RGB and DC, which both required more than two hours. After one year of follow-up, patients in the VG group showed the greatest weight loss (133 pounds) compared to those who received RGB (118 pounds), DC (114 pounds) and BAND (70 pounds). This data suggests that the best bariatric operation for patients older than 50 years of age is vertical gastrectomy because it achieves the greatest weight loss results with the shortest operative time and the least number of complications.

"Bariatric surgery is not cosmetic, particularly in older patients. In many cases, it is the last option for patients whose obesity puts them at risk for serious health complications and even death," said Paul T. Cirangle, M.D., a study investigator from California Pacific Medical Center. "It is important for us to know, especially as these surgeries become more prevalent, which operation is best for each patient."
