(Reuters Health) - People who have weight-loss surgery for extreme obesity may lose more weight with an older operation known as Roux-en-Y gastric bypass than with a newer sleeve gastrectomy procedure, a small U.S. study suggests.

Not really new... reports and studies have shown RNY has a slightly higher set of numbers than the sleeve for a while now in regards to losses and % kept off after X time has past.

"patients who had sleeve gastrectomy operations between 2006 and 2009, before this type of weight-loss operation was widely accepted "

I wonder if a that time sleeves were larger than they are now, because the procedure was newer?

Even the RNY has had changes since it's inception, but mainly due to improvements in medical equipment. I'm sure those same changes effected the sleeve as well.

I think this is pretty old news as others have said.

When I entered the program, I knew up front that RNY loses more than VSG by percentages over time. But the research is showing that over an 18month time frame, the loss percentages are very very close for both surgeries.

@FluffyChix, I agree all the research I've done this past year showed the same thing. Hence why I chose the sleeve over the other options.
