What is Duodenal Switch Surgery?

Duodenal switch surgery, also known as biliopancreatic diversion with duodenal switch (BPD-DS), is a highly effective and complex weight loss procedure designed for individuals with a body mass index (BMI) above 40 or those suffering from obesity-related health issues. This procedure combines restrictive and malabsorptive techniques to promote significant weight loss and improve overall health.

The duodenal switch procedure is an outpatient bariatric surgery performed under general anesthesia. It comprises two stages: the sleeve gastrectomy and the intestinal switch or bypass of the upper half of the small intestines.

Duodenal switch surgery can be performed using a minimally invasive laparoscopic technique. Beltre Bariatrics uses the less invasive laparoscopic method, involving small “keyhole” incisions and the use of small tools to access the surgical site. This results in reduced scarring and faster recovery compared to open surgery.

How Duodenal Switch Surgery Works

The duodenal switch procedure works by removing a portion of the stomach, creating a smaller stomach pouch, and limiting the amount of food one can eat at one time. This restrictive aspect helps control one’s food intake and promotes satiety with smaller portions.

The other aspect of the surgery involves rerouting a section of the small intestine, allowing food to bypass a significant portion of the digestive tract. As a result, fewer calories and nutrients are absorbed from your food, leading to additional weight loss.

In recent years, the BPD-DS procedure has evolved, with the emergence of a modified technique known as SADI-S (Single Anastomosis Duodeno-Ileal Bypass with Sleeve Gastrectomy), also referred to as the Loop Duodenal Switch.

SADI-S is the most commonly performed variation of the traditional duodenal switch surgery. In this modified procedure, the surgeon creates a single anastomosis, bypassing a portion of the small intestine and connecting the duodenum to the ileum or lower half of the small intestines. By streamlining the surgical process, SADI-S offers potential benefits such as reduced operative time and improved surgical outcomes. As with any surgical decision, the BPD-DS procedure, whether traditional or SADI-S, should be thoroughly discussed and evaluated with Dr. Beltre to determine the most appropriate option for you based on your unique needs and medical condition.

Recovery & Results After Duodenal Switch

Following duodenal switch surgery, our caring team will closely monitor your recovery and provide detailed post-operative instructions. While individual results may vary, many patients experience significant and sustained weight loss after the procedure, leading to improved quality of life and reduced obesity-related health issues.

The amount of weight you can expect to lose with duodenal switch surgery can vary depending on factors such as starting weight, adherence to post-operative guidelines, and lifestyle changes.

On average, patients can expect to lose significant weight with this procedure. Most patients experience a weight loss of 80% of their excess body weight within 24 months after duodenal switch surgery. However, it’s important to note that individual results may vary, and long-term success depends on maintaining a healthy lifestyle, including regular exercise and a balanced diet after the surgery.

FAQs About Duodenal Switch

Are you curious about the duodenal switch surgery? Get answers to commonly asked questions right here.

Is duodenal switch surgery reversible?

While technically possible, reversal is a complex and risky procedure, so thoroughly discussing the decision with Dr. Beltre beforehand is essential.

What is the expected recovery time after duodenal switch surgery?

Recovery times may vary, but most patients can resume normal activities within 2 to 3 weeks.

Will I need to follow a special diet after the procedure?

Yes, our nutritionists will provide you with a customized diet plan to ensure proper healing and weight loss success.

Are there any potential risks or complications associated with duodenal switch surgery?

Like any major surgical procedure, duodenal switch surgery carries certain risks and potential complications. Some common concerns include malnutrition or nutritional deficiencies due to reduced nutrient absorption, the need for supplements to ensure adequate vitamin and mineral intake, and the possibility of experiencing dumping syndrome, a condition characterized by rapid gastric emptying leading to nausea, weakness, and diarrhea. Proper post-operative care, regular follow-ups with the healthcare professionals at Beltre Bariatrics, and adherence to dietary guidelines can help minimize these risks and optimize the long-term success of the duodenal switch procedure.

What is the difference between duodenal switch, roux-en-y gastric bypass, and gastric sleeve procedures?

Duodenal switch, gastric bypass, and gastric sleeve procedures are effective weight loss surgeries, but their approach and outcomes differ.

The duodenal switch involves restrictive and malabsorptive techniques, reducing stomach size and rerouting a portion of the small intestine. Gastric bypass surgery creates a smaller stomach pouch and directly connects it to the small intestine, bypassing a section of the stomach. On the other hand, the gastric sleeve procedure involves removing a large portion of the stomach to create a smaller, banana-shaped stomach. Each procedure offers unique benefits and considerations, and the choice of surgery depends on individual factors, such as BMI, health conditions, and weight loss goals.
