The SIPS Technique SADI-S vs. BPD-DS

/

SIPS stands for stomach intestinal pylorus sparing. This is a variation on the traditional duodenal switch (BPD-DS) known as single anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) or single loop DS. SADI-S maintains more of the small intestine, and transects it at one point rather than two. Dr. St. Laurent performs SIPS/SADI-S because it reduces the risk of complications.

Duodenal Switch Explained by Dr. St. Laurent

Dr. St. Laurent presents a detailed overview of a laparoscopic loop duodenal switch procedure. Through an incision on the left side of the patient, Dr. St. Laurent dissects the lower portion of the stomach before dividing the duodenum to achieve duodeno-ileal anastomosis. After inserting a Jackson Pratt drain on the lower border of the stomach to remove any leftover abdominal irrigation, the abdomen is closed with sutures. We can provide more information about this bariatric surgery option during your visit to our Houston area practice.

Risks and Benefits of Duodenal Switch Surgery

Risks of SADI-S

Common risks after duodenal switch surgery include acid reflux (GERD), gallstones, and loose bowel movements. Because of the nature of the surgery, there is also an increased risk of malnutrition and vitamin deficiencies. Since our Houston area practice performs SADI-S rather than BDP-DS, patients are less likely to experience nutritional deficiencies from malabsorption.

Benefits of SADI-S

Loop duodenal switch surgery provides more dramatic weight loss results than other bariatric surgery procedures. It may also be a better option than gastric bypass for morbidly obese patients. For people who have attempted a different bariatric option in the past with lacking results, that procedure can likely be converted into a duodenal switch to promote additional weight loss.

Candidates for Duodenal Switch Surgery

BMI of 50 or Higher

A duodenal switch is ideal for people with a BMI of 50 or higher, which is the Class 3/severe obesity range. The bariatric procedure will typically help these patients lose a substantial amount of their excess weight.

BMI of 45 with Obesity Comorbidities

Duodenal switch may also be recommended for patients with a BMI of 45 or greater with comorbidities. These health conditions include type 2 diabetes, high blood pressure, and sleep apnea.

Revision Bariatric Surgery

If a LAP-BAND®, sleeve gastrectomy, or gastric bypass was ineffective, it can be converted into a SADI-S. This revision bariatric surgery option is common for failed gastric sleeve and gastric bypass procedures.

Healthy Enough to Undergo the Procedure

While SIPS has a lower risk of complications than BPD-DS, it is still a complex surgical procedure. Patients should be in good health and able to undergo surgery without unnecessary risk of complications.

How Do We Determine Duodenal Switch Pricing?

The cost of duodenal switch surgery varies by patient since each procedure is personalized to their needs. During a consultation at our Houston area practice, we can provide a breakdown of the various costs involved and discuss the different factors that affect the price of your surgery.

The Surgeon Matters

One significant cost factor is the choice of surgeon. Although there are other bariatric surgeons who offer lower prices, the cost of undergoing treatment with a highly skilled and respected surgeon like Dr. St. Laurent ensures you will receive the highest standards of care as well as ongoing support.

Insurance and Financing

If we find that your insurance will not cover the full cost of SIPS/SADI-S, we can review available financing options that will make the procedure more affordable.

Here's a look at how duodenal switch surgery works...

The Surgical Process

A loop duodenal switch may be what you need to shed excess weight and address serious health concerns. 

Here is a simplified step-by-step look at the loop duodenal switch process:

A loop duodenal switch may be what you need to shed excess weight and address serious health concerns. 

Initial Consultation

During your initial visit to our Houston area practice, we will review your medical history and go over your weight loss goals. We can answer any questions you have, and compare duodenal switch to gastric bypass and other weight loss surgery options. We want you to feel confident and informed about your health decisions.

Administering Anesthesia

Loop duodenal switch surgery is performed using general anesthesia and local anesthetic. This ensures patients are not conscious during the bariatric procedure and feel no pain.

Laparoscopic Incisions

Dr. St. Laurent is a skilled laparoscopic surgeon. Laparoscopic surgery uses precise instruments that are inserted into the abdomen through small incisions. This leads to less scarring, fewer risks during the procedure, and faster healing times than open surgery.

Adjusting the Stomach
and Intestine

With the incisions made, Dr. St. Laurent first performs a gastric sleeve to reduce the size of the patient's stomach. Next, he will reroute the gastrointestinal tract to bypass about half of the small intestine.

Completing the Procedure

With all adjustments to the stomach and intestine completed, sutures are placed to prevent gastric leak and post-operative hernia.

Recovery What to Expect after Duodenal Switch

After the Procedure

Patients are monitored after surgery to ensure no immediate complications are present. We will provide detailed instructions on how to manage discomfort and other surgical side effects.

Changes to Your Diet

As with other bariatric surgeries, patients will have a transitional diet while they recover. Starting with liquids, they will slowly reintroduce solid foods. We'll work with you to ensure your daily diet is healthy, nutritious, and helps you achieve your weight loss goals.

Returning to Normal Activities

Patients are usually able to return to work after two weeks, with full recovery in about six weeks. Waking is encouraged each day to help promote circulation.

Comparison SADI-S vs. Other Weight Loss Surgeries

Duodenal switch surgery is more complicated than other bariatric procedures. That said, the nature of the SIPS/SADI-S procedure allows it to achieve greater weight loss than gastric bypass or sleeve gastrectomy. The duodenal switch is also a potential revision option after a failed gastric bypass or sleeve gastrectomy.

During the consultation process at our office serving the Houston area, we can assess your current health and review your wellness goals. Dr. St. Laurent can then compare different procedures and their potential outcomes. In some cases, less invasive bariatric techniques may be ideal.

If you would like a general overview of different weight loss surgery options, we created a convenient series of tables that compare surgical procedures, their advantages, the potential complications, and projected weight loss after surgery is completed.
