Duodenal Switch

Is excessive weight putting your health at risk? Has weight loss been a constant struggle? We may have the solution!

Duodenal switch surgery can help patients lose a significant amount of weight and keep it off for years to come.

Drs. Sergio A. Del Hoyo and Christian O. Ramirez in Puerto Vallarta, Mexico, can help transform your life through a duodenal switch.

How Does Duodenal Switch Surgery Work? It Restricts Food Consumption and Caloric Absorption

Duodenal switch surgery,  also known as a biliopancreatic diversion and biliopancreatic diversion with duodenal switch (BPD/DS), shrinks the size of your stomach to reduce the amount of food you can eat and bypasses a large portion of the small intestine to minimize the number of calories your body absorbs. In other words, this type of weight loss surgery is both restrictive and malabsorptive. 

Why Bariatrics Health Mexico? How Medical Tourism Can Save You Thousands

Medical tourism is a consistently growing industry. People from the U.S. and Canada are discovering they can have life-changing weight loss surgery for a fraction of the price in a popular destination. Many patients come early to vacation with family or friends before their procedure. 

Apart from dramatic savings, patients choose Bariatrics Health Mexico in Puerto Vallarta because of our quality of care, highly trained bariatric surgeons, and pristine, safe facilities.

Duodenal switch is performed laparoscopically and takes around three hours to complete. The patient will stay two nights in the hospital. This bariatric surgery has two steps, which can be completed during one procedure for patients who are not high-risk.

Step One: Gastric Sleeve

The first step of the duodenal switch is to perform sleeve gastrectomy. During a duodenal switch, however, our surgeon removes slightly less of your stomach than they would during a gastric sleeve procedure. By reducing the size of your stomach, the calories you can consume will be restricted.

Step Two: Intestinal Bypass

The second step of duodenal switch surgery is to bypass your small intestine. There are two ways to perform this part of the surgery, through the biliopancreatic diversion (the original) or the SADI-s, or loop procedure. Each version will bypass a large portion of your small intestine, restricting the number of calories your body absorbs.


The Modern Duodenal Switch

SADI-S procedure

SADI-S, or the loop duodenal switch, is similar to the biliopancreatic diversion in that it still divides your small intestine near the duodenum and then reattaches the lower portion to the top, bypassing a large section of the intestine. However, there are two key differences in these procedures.

Intestinal Bypass

During the traditional duodenal switch, around 80-90% of your small intestine is bypassed compared to 50-60% in the SADI-S procedure.

Simplified Process

Unlike the original method that attaches your small intestine in two places, SADI-S loops your small intestine, allowing it to reconnect in one location.


Gastric Bypass vs. Duodenal Switch What Is the Difference?

Duodenal switch surgery is similar to gastric bypass, or the Roux-en-Y method, in that both reduce your stomach size and bypass your small intestine. However, gastric bypass focuses more on restriction, while duodenal switch focuses more on malabsorption. During the Roux-en-Y procedure, your stomach size is reduced by about 70-80%, and about 30% of your small intestine is bypassed. During duodenal switch surgery, your stomach size is reduced by around 60-70%, and about 75% of your small intestine is bypassed.

Our Puerto Vallarta team can help you determine the best procedure for your needs during your consultation.
