Long alimentary limb duodenal switch (LADS): a short-term prospective randomized trial

At 12 months, weight loss was lesser in the long alimentary limb group. There was however no difference in the remission of co-morbidities and higher levels of vitamin D, manganese, and copper. Gastrointestinal adverse effects and the need for pancreatic enzymes were less with similarly excellent quality of life at 12 months. Longer follow-up is necessary to evaluate long-term weight loss and nutritional deficiencies.
