Technical Considerations of Duodenal Switch and Its Variants

Most modern bariatric operations are now based upon the performance of a gastric restriction procedure, responsible for the short-term weight loss, and a gastrointestinal bypass, which should warrant the maintenance of weight loss over time. But due to concerns of nutritional deficiencies, the more malabsorptive operations have declined in numbers with the restrictive varieties becoming more popular [1]. But there still remains a definite role for more malabsorption even as we try to become more conservative in the choice of procedure. This is applicable, more so in super obese patients and in patients with a severe metabolic syndrome [2].
