TraditionalDuodenal Switch
The traditional duodenal switch (DS), like the gastric bypass (RYGB) and the ModDS, is both a malabsorptive and restrictive surgery.
What is traditional duodenal switch weight loss surgery?
The combination of malabsorption and restriction makes the traditional DS, ModDS surgery, and RYGB extremely effective at enabling patients to lose weight and keep it off. Patients can lose more weight with bariatric surgeries that have both restrictive and malabsorptive components.
Traditional duodenal switch:
Is it right for me?
The traditional DS procedure was first done in 1986. In this procedure, over 90% of the small intestine was bypassed, which produced excellent weight loss results — but it came with a significant risk of long-term complications. Most of the studies showed that such risk to be over 30%. Because of this high complication rate, very few surgeons in the United States perform this surgery, and it now represents less than 5% of all weight loss surgeries done in the country today.
Traditional duodenal switch vs. modified duodenal switch
There are two main differences between the traditional DS and the ModDS:
- The biggest difference between these two procedures is that the ModDS only bypasses 50% to 60% of the small intestine, which results in a significantly reduced rate of diarrhea, malnutrition, and vitamin deficiencies while maintaining the same excellent weight loss.
- The second major difference is that the ModDS does not involve the second anastomosis (connection of bowel) downstream. This second connection was intended to divert bile to the bowel further downstream and prevent bile from refluxing back into the stomach. However, with the pylorus intact (a valve that prevents bile from going into the stomach), this second connection is considered unnecessary by many surgeons.
Risks of traditional duodenal switch surgery
Further, this second connection, like the gastric bypass, increases the risk for life-threatening small bowel obstructions from internal hernias.
This is almost never encountered with the ModDS procedure. Although the traditional DS provides for excellent weight loss, itdoes come with increased risk.
Our approach at Roller Weight Loss
