what is an rny procedure?
The Roux-en-Y gastric bypass (RYGB) is the most commonly performed bariatric procedure in the US. However, the long-term failure rate after RYGB is 20 to 35 percent.[1] Particularly in superobese patients (BMIâ¥50Kg/m2), this failure rate can be as high as 40 to 60 percent, depending on how failure is defined.[2]
