In a recent review article  published in the September 2015- Volume 42:10 of General Surgery News,  the surgical outcomes of different procedures were summarized. There were evaluated based on a number of measures, including re-operation rates. So interesting to note that the re-operation rate of the duodenal switch is the lowest of all surgical procedures.

Adjustable gastric banding had the highest reported re-operation rate. To be noted is the longer the time lapse the higher the need for re-operation for the band.
