Over the last few years, a less invasive version of the traditional duodenal switch (DS) has become an option for many patients.
Faster surgery and reduced risk: Modified duodenal switch
By having one connection instead of two, the surgery is performed more quickly and with less risk of leaks, thereby decreasing the risk of surgery. Furthermore, in the ModDS procedure, we only bypass about 50% of the small intestine — whereas in the traditional DS, 85% to 90% of the small intestine is bypassed. This helps to avoid the main risks of the traditional DS procedure, which are debilitating malnutrition and diarrhea. Both of these are very uncommon in the ModDS procedure. Although the traditional DS led to massive weight loss, a significant number of patients suffered persistent vitamin or protein malnutrition despite taking all the proper supplementation.
