Duodenal Switch Surgery
The primary advantage of duodenal switch (DS) surgery is that it combines intake restriction with substantial calorie malabsorption results in a very high percentage of excess weight loss for super morbidly obese individuals, with a very low risk of significant weight regain.
About Duodenal Switch Surgery
The restrictive part of the duodenal switch procedure is achieved via partial gastrectomy (removal of part of the stomach), which reduces the size of the stomach. Similar to a gastric sleeve.
The duodenal switch keeps the pyloric valve between stomach and small intestine intact.
The malabsorptive component of the duodenal switch procedure is achieved by rearranging the small intestine so as to separate the flow of food from the flow of bile and pancreatic juices. Reducing the amount of bile and pancreatic juices the food comes in contact with reduces the amount of food that is digested and decreases absorption of some calories and nutrients.
Further down the digestive tract, the separated portions of the small intestine are rejoined; food and digestive juices begin to mix, and calories and nutrients are absorbed along the short length of the small intestine prior to the junction with the colon.
Duodenal Switch Surgery
- Averages 80-85% excess weight loss*
- Combination of the Sleeve and Bypass
- Minimal to no weight regain, even 15-20 years after the procedure*
- More vitamin requirements
- Causes more gas than Bypass
- Usually reserved for patient with BMI of 50 or greater
- Can be done with a BMI lower than 50, depending on insurance
Possible Risks and Complications of DS Surgery
All surgical procedures involve a degree of risk, however this must be balanced against the significant risks associated with severe obesity. Some of the surgical risks or complications for this procedure are: perforation involving small bowel, duodenum, or stomach causing a leak, infection, abscess, deep vein thrombosis (blood clot), and pulmonary emboli (blood clot traveling to the lungs). Longer-term risks include hernia and bowel obstruction. Malnutrition is a preventable risk after Duodenal Switch with adequate protein and vitamin supplementation.
