What is Laparoscopic Duodenal Switch Surgery?

Commonly referred to as a laparoscopic duodenal switch, surgeons perform biliopancreatic diversion with a duodenal switch (BPD/DS). Though, it is a surgical weight loss procedure that uses both restrictive and malabsorptive techniques to facilitate weight loss. Eventually, surgeons typically perform this procedure laparoscopically, giving it the well-known name laparoscopic duodenal switch or LDS.

Furthermore, the duodenal switch is a two-part surgery in which surgeons remove a large portion of the stomach (about 75%). On the contrary, surgeons make it smaller using the same technique as gastric sleeve surgery, and then they alter the digestive system by rerouting the small intestine.

Nonetheless, the surgical combination results in significant weight loss for most patients.  Because the smaller stomach size naturally limits portion control. Moreover, the alterations to the small intestine prevent the body from absorbing all the calories from the food that is consumed, thereby preventing the patient from overeating.

Many times, surgeons perform duodenal switch bariatric surgery as two separate surgeries with a few months in between to reduce risks and prevent long surgical times.

Why consider Laparoscopic Duodenal Switch Surgery?

However, patients who have had gastric sleeve surgery and failed to lose the amount of weight they desired or have experienced weight regain can benefit from undergoing a Bariatric Revision

Moreover, converting gastric sleeve weight loss surgery to a duodenal switch adds the malabsorptive technique to the restrictive technique stopping weight gain and prompting further weight loss.

Historically, BPD-DS surgery has yielded tremendous weight loss and many patients have experienced remission or elimination of many serious, and even life-threatening, weight-related medical conditions after duodenal switch weight loss surgery.

Regardless, losing weight through duodenal switch surgery can lower the risks of many serious conditions including:

How Much Weight Can I Lose with the Procedure?

Nonetheless, patients who have had duodenal switch surgery often lose between 65% and 80% of their excess body weight during the first 12 months.

In addition, the formula determines how much excess weight an individual is carrying. FInally, it is calculated by subtracting their ideal weight or goal weight from their current weight.

For Example:

A patient who currently weighs 325 pounds. Whereas, weight is 150 pounds has 175 pounds of excess weight. In reality, if they were to lose 70% of their excess weight (approximately 122 pounds). They would reduce their current weight from 325 to about 202 pounds.

Despite this, patients can lose additional weight or maintain their weight loss by persevering with their healthy low-calorie diet, ongoing exercise plans, and continued behavior modification. Although, most patients will reach their goal weight after 24 months.

BMI (body mass index) of 40 or higher.

A BMI of 35 or higher and suffering from serious weight-related health issues, such as uncontrolled diabetes (Type 2).

Have had previous unsuccessful bariatric procedures.

meanwhile, patients who are considering duodenal switch surgery must be committed to making permanent changes in their lifestyle including diet and exercise. In fact, they must also be dedicated to lifelong participation in follow-up care and utilization of support systems.

How much does Duodenal Switch Surgery cost?

In reality, the average cost of duodenal switch surgery in the United States is between $21,000 and $29,000. In fact, insurance may cover Duodenal Switch (DS) surgery, offsetting the amount paid by the patient. At the same time, the use of FAS HSA, or other resources may help reduce patient out-of-pocket responsibility.

While comparing costs associated with the duodenal switch procedure. Indeed, keep in mind that most quotes are not all-inclusive, and they do not include many necessary fees. For instance, the quote you receive may not include the fee for anesthesia, the operating room, or the surgical facility.

When will I start seeing Results from the Procedure?

Typically, patients lose weight rapidly following duodenal switch surgery. Despite this fact, patients see the most dramatic loss of their excess weight in the first three months. Even so, many patients report losses of between 40 and 90 pounds by 90 days post-op.

Even though it may seem, that weight loss speed may vary by patient. That being said, it depends on whether the surgery was completed in one surgical session or split into two procedures.

However, duodenal surgery helps patients lose a tremendous amount of weight for the following reasons:

How long will the Results from Duodenal Switch Surgery last?

Granted, results of duodenal switch surgery are expected to last a lifetime provided that the patient continues to maintain their commitment to practice and implement the necessary lifestyle changes like diet and exercise.

With this in mind, the surgery is meant to be used as a tool to help the patient achieve their weight loss goal but long-term success requires ongoing patient dedication.

Are there any Risks Associated with Duodenal Switch Surgery?

In the final analysis, most duodenal switch side effects are mild and can be controlled or corrected. However, duodenal switch, like any surgical procedure, has associated risks. Still, some possible risks include:

  • Infection.
  • Excessive Bleeding.
  • Breathing or Lung Issues.
  • Gastrointestinal System Leaks.
  • Deep Vein Thrombosis or Blood Clots.
  • Negative Reaction to General Anesthesia.

Some rare, but long-term, side effects of duodenal switch surgery include:

  • Ulcers.
  • Hernias.
  • Gallstones.
  • Malnutrition.
  • Bowels Obstruction.
  • Stomach Perforation.
  • Hypoglycemia or Low Blood Sugar.
  • Dumping Syndrome – Diarrhea, Nausea, or Vomiting.

Is Laparoscopic Duodenal Switch Surgery Reversible?

Duodenal switch surgery is considered permanent. However, a portion of the procedure may be reversed in certain cases.

Since the surgeon removes a portion of the stomach during the “gastric sleeve” portion of the surgery there is no way to reverse this. Yet still, it is possible, in some cases, to reverse the alterations to the small intestine for patients who experience digestive issues after duodenal switch surgery.

How do I Know if Duodenal Switch Surgery is Right for Me?

Patients who suffer from severe obesity are normally good candidates for duodenal switch surgery. Equally important, a consultation with a bariatric surgeon is an excellent way to learn more about different weight loss procedures.  Furthermore, determine if traditional duodenal switch surgery or the SADI-S technique may be the best option for you.

Traditional Laparoscopic Duodenal Switch Surgery vs. SADI-S

As a matter of fact, traditional duodenal switch surgery alters two portions of the small intestine. However, there is a modified duodenal switch (loop duodenal switch) or SADI-S that alters only one portion of the small intestine. In fact, the SADI-S Technique has been found to reduce the chances of patient malnutrition which can be a long-term side effect of duodenal switch surgery.

How Long is the Recovery from Duodenal Switch Surgery?

Duodenal switch recovery will vary for each patient and will depend on many factors, accordingly. In addition to the technique used for the duodenal switch procedure. Therefore, the general health of the patient and any complications that may arise are important factors too. 

Overall, this is a more difficult surgery and takes longer to perform than most other bariatric weight-loss procedures which makes the duodenal switch recovery time significantly longer as well.

Afterward, many individuals experience pain for about a week to ten days which can be managed with pain medication that the surgeon will prescribe. The sites where the incisions were made may also be swollen and tender for about a week.

Additionally, it is important to follow all of the aftercare directions provided by the surgeon to mitigate the risks of infection or other complications. No matter how these instructions will also detail any activity restrictions patients must adhere to as they recover to prevent any damage to the surgical sites.
