This book provides extensive information on the duodenal switch and all of its derivatives. The number of procedures performed is progressively increasing, as cases of obesity are on the rise and patients' body mass index (BMI) is getting higher. It discusses all the techniques involved in the duodenal switch procedure and its derivatives used in the primary and revision situations. Readers will learn what the procedure can offer not only in terms of weight loss, but also its potential with regard to metabolic diseases, since some data indicates that the duodenal switch may lead to rapid resolution of diabetes and other comorbidities.

The most important information on the duodenal switch is gathered in a single volume and includes its benefits for metabolic diseases. This book will give healthcare professionals new confidence with regard to this procedure and may serve as a reference guide not only for the bariatric community (surgeons, PA, ARNP, nutritionists) but also for teaching new residents and fellows.
