Failure of Roux and Y gastric bypass
Failure of Roux and Y gastric bypass (RYGB) is as high as 25%, it means that every forth patient is not loosing enough weight or gaining weight back. This number can reach 50% for patients with a BMI of 50 or more. Recent data showed that only Duodenal Switch (DS) is a successful revisional surgery for patient with past RYGB. Revision to DS can give a patient a chance to achieve BMI of 26 and loose 90 % of excess weight. These results are much better than original RYGB.For comparison data from MBSC showed that RYGB to RYGB revision is much less effective than primary operation with only 43 % of EWL. Many bariatric surgeons blamed patient for failed surgery but the fact is that surgery should be blamed for patient failure.
