A new study reported in JAMA Surgery investigates the long-term durability of weight loss after bariatric surgery. Led by Dr. Matther L. Maciejewski from the Durham Veterans Affairs Medical Center in Durham, NC, the researchers used data on mostly (over 73 percent) male veterans from the federal Veterans Administration. Participants' BMIs on average ranged from 43 to 48, putting them in the extremely obese category. They underwent one of 3 types of bariatric surgery: about 1800 had Roux-en-Y gastric bypass (RYGB); about 250 had adjustable gastric banding (AGB); about 380 had Sleeve gastrectomy (SG); and about 5300 served as weight-matched non-operated controls. The men in each group averaged between 52 and 53 years old.

Four years post-surgery, all the different surgeries resulted in a loss of initial body weights: 28 percent in the RYGB group, 11 percent in the AGB group, and 18 percent in the SG group, indicating a substantially larger loss with RYGB.

By the 10th year post-surgery, the RYGB group lost 21 percent more of their baseline weight than did the non-surgical control group: a difference that was statistically significant — the RYGB group had lost nearly 29 percent of their initial body weight at that time, while the control group lost only about 7 percent.

What about the sleeve and banding it wasn't worth mentioning? How much did they lose?

Everything I've read says to date sleeve weight loss is below rny but it wouldn't have been around long enough for longitudinal studies. Band has up to 50% failure and revision rate at 10 years so that may be why it wasn't included with such a small band sample.
