A new matched-paired study published online in Archives of Surgery found that both
Roux-en-Y gastric bypass and
gastric band bariatric procedures have excellent weight loss outcomes at six years. The findings indicated that gastric bypass patients lost 78.5 percent of their excess weight after six years, and gastric banding patients lost 64.8 percent. For the study, researchers conducted a matched-pair analysis of 221 patients who received a gastric bypass versus 221 patients who received a gastric band procedure in 1998 through 2005. Their analysis indicated that, on average, maximal weight loss was achieved 18 months after a gastric bypass procedure, while maximum weight loss was achieved on average 36 months after gastric banding. At the six year mark, both groups had experienced significant reductions in Body Mass Index (BMI), with just 2.4 percent of the Roux-en-Y group having a BMI greater than 40, and 13.8 percent of the gastric banding group. Both groups also reported improved quality of life. The bypass group saw better improvements in lipid profiles and fasting glucose levels, but there were significantly more early complications after Roux-en-Y (17.2%) than after gastric banding (5.4%). This is not surprising being that Roux-en-Y is more complex surgically, requiring both a longer operative time and longer hospital stay.
