What is Duodenal Switch, aka DS




In this procedure, the surgeon removes about 80 percent of the stomach, forming a thin sleeve-like stomach. The valve that releases food to the small intestine remains (duodenal switch) along with a limited portion of the small intestine that normally connects to the stomach (duodenum). The surgery bypasses the majority of the intestine by connecting the end portion of the intestine to the duodenum near the stomach (biliopancreatic diversion). This weight-loss surgery is effective but has more risks, such as malnutrition and vitamin deficiencies, and requires close monitoring.


This is a procedure that is nice in the sense that the first half of the surgery is a Vertical Sleeve Gastrectomy and the second half is the DS, or bypassing of intestine. There is no concern for dilating a stoma as in Gastric Bypass and the long term weight loss is the best of all surgical procedures. The thing about WLS is that the less the risk, the less the weight loss. The greater the risk in surgery the greater the weight loss. This is the greatest risk of all surgery types for malnutrition and various vitamin deficiencies yet it provides the best long term weight loss stats. It does not have "more" complications than Gastric Bypass but if complications occur, the complications are greater in nature.


By the time you have this procedure you will not absorb 80% of fat, 50% of protein, and about 40% of complex carbs. A high fat diet is not only permissible with this surgery type, it is necessary.


One down side to this surgery types more-so than other surgery types is that if you consume a great deal of white carbs such as flour, sugar, rice, or pasta you will have gas that is not pleasant to the nose. This happens with RNY as well but not to the same degree.


Not all surgeons can do this surgery type. It requires a skill as well as an art, much experience is necessary to perform this particular surgery safely and effectively. 


Advantages of this surgery:


1) Best weight loss and best long term weight loss stats of all surgery types.

2) Not only the ability but the necessity for the patient to consume a very high fat, high protein, low carb diet.

3) A more normal stomach than bypass, there is no pouch and no stoma.

4) For Type II diabetics this surgery provides a 97% reversal of diabetes.  As a matter of fact, doctors in Europe are doing this surgery in normal size adults to treat uncontrolled diabetes.


Three disadvantages of this surgery:


1) Highest risk surgery type when using inexperienced surgeons.

2) Highest risk for vitamin and mineral deficiencies.

3) Not appropriate for vegetarians or vegans or those unable to comply with a high fat diet.
