Why Select SADI-S or Duodenal Switch Surgery?

The SADI-s procedure and duodenal switch surgery in Tijuana offer more significant modification of the intestines than Roux-en-Y bypass to allow for greater malabsorption, so patients absorb fewer calories from the food they consume. When compared with gastric sleeve or gastric bypass, SADI-s and duodenal switch surgery also offer a better chance of controlling diabetes, in addition to more significant weight loss. Additionally, duodenal switch patients have a lower risk of developing ulcers than those who undergo gastric bypass.

SADI-S and Duodenal Switch Surgery in Tijuana

Duodenal switch surgery and its newer variant, SADI-s surgery, are two of the most effective bariatric procedures for super-obese patients struggling to lose massive amounts of excess weight. 

These bariatric procedures have restrictive and malabsorptive elements taken from gastric sleeve and RNY gastric bypass to promote significant weight loss and resolve obesity-related health problems like type II diabetes, high blood pressure, high cholesterol, and other metabolic disorders. Undergoing one of these procedures in Tijuana, Mexico, is a safe and economical way to get back on the road to health.

Understanding Duodenal Switch and SADI-S Surgery

To make an informed decision about which type of bariatric surgery is best for your needs, you should understand what each procedure involves. As with Roux-en-Y weight loss surgery, duodenal switch and SADI-s involve anastomoses. An anastomosis occurs when two pieces of the intestine or a section of the stomach and intestine are joined together. Duodeno-ileal refers to the two areas connected during weight loss surgery. The duodenum is the first part of the small intestine, while the lower portion is called the ileum.

I had my surgery almost a week ago. I was totally blown away by the level of care and professionalism that I’ve been given, from the very beginning of this journey. Martha Mejia was my initial contact and turned out to be my constant source of encouragement, information, and support. Dr. Garcia is second to none. I could not have been in better hands. I think the whole medical staff came to my room to check on me and to give me information about my surgery and recovery. The nursing staff and technicians monitored me continuously. I had misgivings about undertaking a surgery like this after age 65, but it was the right decision because I found the right team.

How Does a Duodenal Switch Procedure Work?

Duodenal switch surgery was developed as an improvement on a procedure called biliopancreatic diversion (BPD), which is why you may see this obesity surgery referred to as DS-BPD. The original surgery divided the patient's stomach in half horizontally and rerouted the digestive system. Because the amount of the small intestine bypassed was extremely long, many patients suffered extreme malnutrition and dumping syndrome. The duodenal switch was developed to alleviate the adverse side effects of BPD.

Instead of sectioning off the stomach horizontally, duodenal switch surgery reduces the stomach by about 75%, shaping it into a slightly larger gastric sleeve. The smaller pouch limits stomach capacity, while intestinal rerouting is less severe to allow food to remain longer in the digestive tract. These modifications reduce dumping syndrome and malnutrition side effects.

Sometimes surgeons perform duodenal surgery in two separate steps when weight loss patients have an extremely high body mass index (BMI) to reduce the risks involved and shorten surgical time.

  • Step one: Gastric sleeve surgery to reduce stomach size and promote initial weight loss.
  • Step two: After two to three months, a second surgery alters the digestive system to reduce the amount of time ingested food stays in the body, with fewer calories absorbed.

Duodenal switch bariatric surgery in Tijuana leads to dramatic weight loss and remission of many obesity-related health issues. However, because of its complexity and risks, doctors developed a modified variation called the Single Anastomosis Duodeno-ileal Bypass With Sleeve Gastrectomy, commonly called SADI-s.

How Does SADI-S Surgery Work?

SADI-s is a further variation, also known as single-loop duodenal switch or Stomach Intestinal Pylorus Sparing (SIPS) surgery. Its purpose is to reduce other risks and complications duodenal switch surgery presents through only one anastomosis. It's also less invasive than a bypass with sleeve gastrectomy or duodenal switch surgery. 

The malabsorptive portion reroutes part of the small intestine, creating two separate pathways and one common channel. The shorter digestive loop of the two pathways allows food to flow from the stomach to the common channel.

The longer pathway, the biliopancreatic loop, carries bile from the liver to the common channel. 

This diversion limits the time that food mixes with digestive juices and reduces the number of calories a patient’s body absorbs, resulting in increased weight loss. Some patients may also have their gallbladder removed during this bariatric procedure, as many patients who lose significant amounts of excess weight require gallbladder removal at a future date to avoid gallstones.

Dr. Fernando Garcia – A Visionary Leader in the Field of Bariatric Surgery

Dr. Garcia is a veteran bariatric surgeon who has performed over 15,000 successful procedures during his decade-plus career in medicine. Known for his skill, precision, and cutting-edge techniques, he is also often praised for his genuinely compassionate bedside manner and his unwavering dedication to his patients’ well-being and success.

As a provider who has himself transversed the weight loss journey, Dr. Garcia knows firsthand how frustrating and daunting the process can be. He has put great effort and time into creating a comprehensive weight loss program that goes far beyond surgery and incorporates ongoing support groups, nutritional counseling, and extensive email follow-up. Dr. Garcia believes that every patient is entitled to live their best life, free from health concerns and reduced self-esteem associated with obesity. 

Dr. Fernando García obtained his Licensed Physician Degree from the prestigious Universidad Michoacana de San Nicolás de Hidalgo before going on to complete his residency in General Surgery at Hospital General (General Hospital), endorsed by Universidad Autónoma de Baja California (UABC). As a professor of Advanced Laparoscopic Surgery at Universidad Autonoma de Baja California, Dr. Garcia continues to educate generations to come with his innovative techniques. Additionally, he has been on staff at the Instituto Mexicano del Seguro Social for over a decade. 

What Differentiates Dr. Garcia’s Surgical Approach?

When it comes to SADI-s, Dr. Garcia’s approach is a blend of time-tested methods and innovative techniques that he has refined over the years. He uses minimally invasive laparoscopic methods, leading to less postoperative discomfort and a quicker recovery. His cutting-edge techniques also result in smaller incisions, which enhances the final aesthetics of any surgery. 

When it comes to the duodenal switch aspect of the SADI-s, Dr. Garcia’s technique ensures an optimal balance between effective weight loss and nutrient absorption, tailored to each patient's specific needs. The closure methods he employs are designed for both durability and minimal scarring. 

Furthermore, at the Tijuana Bariatric Center, we believe in a comprehensive post-surgical regimen. This includes tailored dietary plans and physical therapy routines to assist patients in their recovery and weight loss journey. This unique combination of tried-and-true practices, personalized care, and an unwavering commitment to excellence in bariatric surgery is what differentiates our practice’s approach to the SADI-s procedure. 

In the Doctor’s Own Words

Having performed a variety of procedures, SADI-s stands out for its innovative approach to weight loss and metabolic balance. What I personally admire most about SADI-s is its combination of sleeve gastrectomy's restriction with the intestinal rerouting's benefits. This harmonious blend ensures effective weight loss while minimizing potential nutrient deficiencies. Each SADI-s procedure is a testament to the adaptability of modern bariatric surgery to meet individual needs. 

Beyond the technical aspects, it's the transformative journey of my patients that truly inspires me. To witness their health revitalize, their energy levels soar, and their confidence bloom is nothing short of awe-inspiring. It's a poignant reminder of why I dedicated myself to this field and the mission of Tijuana Bariatric Center. The SADI-s procedure is more than just an operation; it's a beacon of hope for many, offering them a chance at a renewed, healthier life, and I feel deeply honored to be a part of that journey.

Benefits of Duodenal Switch Surgery

Approximately 99% of those with type II diabetes or high cholesterol, 92% with obstructive sleep apnea, and 83% with hypertension enter remission or are cured following bariatric surgery. Other conditions that can experience significant improvement or resolution include*:

  • Asthma/breathing issues
  • Dyslipidemia
  • Arthritis
  • Headaches and migraines
  • Infertility/PCOS syndrome
  • GERD and acid reflux
  • Heart disease
  • Back and joint pain

Benefits of SADI-S Surgery

Traditional duodenal switch surgery bypasses a much larger portion of the small intestine, leading to persistent malabsorption of vitamins, minerals, and even protein in some individuals. For a small percentage of patients, these deficiencies are only partially corrected using oral replacement supplements, leading to long-term difficulties. 

SADI-s preserves approximately ten feet of the small intestine’s absorptive length instead of the two to five feet from duodenal switch weight loss surgery.
One of the biggest pluses of this bariatric procedure is that once healed, patients can eat “near normal” meals, albeit in smaller portions, than those who undergo a purely restrictive Roux-en-Y bypass, resulting in greater patient satisfaction. Because the small intestine is not divided into two segments in SADI-s, fewer complications occur, including the risk of leaking potentially harmful matter into the peritoneum. The possibility of intestinal entrapment in the space between the intestinal segments is also reduced. Fewer connections translate into a possibly shorter procedure, making it easier to perform in a single session while reducing the chance of hemorrhage and infection.

Preservation of the pylorus, the outlet of the stomach that allows food to pass into the small intestine for digestion, is a significant benefit, as it prevents control of solid emptying while also preventing partially digested food and digestive juices from reentering the stomach.

Other advantages include:

  • Faster recovery, with many patients returning to work a week after surgery
  • Less hunger through the removal of the portion of the stomach that produces ghrelin, the hunger hormone
  • Rapid weight loss with patients losing up to 40 lbs. in the first months and continuing to lose up to 90% of excess weight within six to eight months
  • Regulates sugar levels

Similarities Between Duodenal Switch Surgery and SADI-S

Both techniques are performed through laparoscopic surgery, but some weight loss patients may occasionally require open surgery for various reasons. This decision usually occurs during pre-op consultations. Surgeons can perform both operations in two stages, which is needed to help patients with the highest body mass index achieve sufficient excess weight loss to make the second part of the procedure safer.

The risk of malnutrition remains present with both bariatric procedures, although the single anastomosis duodeno ileal bypass procedure lessens that risk. Patients must follow strict vitamin and mineral supplementation for the rest of their lives.

Differences Between Duodenal Switch Surgery and SADI-S

The Y-shape connection in duodenal switch surgery prevents bile from getting into the
stomach, avoiding stomach discomfort and irritation. It also results in selective fat and nutrient absorption not present in SADI-S because of the multiple channels. The single ileal bypass with sleeve procedure (SIPS) has a reduced operating time of about 30 minutes and a reduced risk of post-surgical complications because of the single intestinal connection. SADI-s preserves approximately ten feet of absorption in the intestines instead of two to five feet associated with traditional duodenal switch surgery.

Shared Benefits

SADI-s and duodenal switch patients experience the following shared benefits:

  • Dramatic long-term weight loss
  • A longer-lasting feeling of fullness
  • Better portion control
  • Less absorption of calories

As patients lose weight, they will realize a significant decrease or resolution of obesity-related diseases, including obstructive sleep apnea, joint pain, etc.

Am I a Good Candidate for Duodenal Switch or SADI-S Surgery?

Duodenal switch surgery or SADI-s isn't for everyone. Your doctor may recommend one of these procedures if you have super morbid obesity and need to achieve excess weight loss greater than patients typically achieve with other surgeries. These weight loss surgeries are usually recommended only after attempting to lose weight by improving diet and exercise habits. 

You'll likely undergo an extensive screening process to see if you qualify. Qualifications include being willing to make permanent changes, including committing to a healthy diet before and after surgery to prevent weight regain. 

These surgical procedures are also performed to reduce your risk of potentially life-threatening metabolic diseases. They are particularly effective for diabetic patients to reduce the problems assisted with insulin-dependent type II diabetes.

To be a good candidate for SADI-s or duodenal switch surgery, you must have a BMI greater than 40 or a body mass index in the 35-39.9 range accompanied by hypertension, type II diabetes, sleep apnea, fatty liver disease, or hyperlipidemia. Many prospective patients have a BMI higher than 50. Typically, you will be 100 pounds or more above your ideal weight.

Are There Any Safety Concerns With the SADI-s Procedure?

Duodenal switch patients should remain aware that this weight loss procedure has drawbacks. As with any surgery, you can expect the following risks:

  • Internal bleeding
  • Infection
  • Blood clots in your legs that can move to the lungs
  • Hernia
  • Death

Because stomach size is reduced, certain foods can cause excessive gas that you may be unable to control. Additionally, patients must augment their diet with vitamins and minerals to prevent poor nutrition. If you follow a proper post-op diet and have realistic expectations, you can manage these potential disadvantages and achieve long-term weight loss.

What Risks are Associated with the Procedure?

The following is a list of potential risks and how Tijuana Bariatric Center responds to each. Our highest priority is to ensure a safe, stress-free surgical journey for each patient. 

  • Risk #1: Surgical complications – As with all surgeries, there's a risk of infection, blood clots, bleeding, and leakage at the surgical site.
    How we address this: Our seasoned medical team uses the latest cutting-edge surgical techniques to minimize these risks. Additionally, we have rigorous post-op care and monitoring to catch and address potential complications early.
  • Risk #2: Nutritional deficiencies – The bypassed segment of the intestine in SADI-s can lead to reduced absorption of certain vitamins and minerals.
    How we address this: We emphasize postoperative nutrition, ensuring patients are on a balanced diet supplemented with essential vitamins and minerals. Regular monitoring of nutrient levels is also conducted.
  • Risk #3: Digestive discomfort – Some patients might experience symptoms like reflux or dumping syndrome post-SADI-s.
    How we address this: Our team provides dietary guidelines to prevent these issues and if needed, prescribes medications to manage symptoms.
  • Risk #4: Cosmetic concerns – Post-surgery scars from the incisions can be a concern for many. Additionally, after substantial weight loss, sagging or excess skin can become evident.
    How we address this: We utilize minimally invasive surgical methods, leading to smaller scars that are less noticeable. With time and proper care, these scars tend to diminish. When it comes to dealing with sagging skin, we guide patients toward the appropriate skin-tightening exercises and skincare recommendations. If necessary, we can refer patients to plastic surgeons for further aesthetic revision.
  • Risk #5: Hair thinning – Rapid weight loss can sometimes lead to temporary hair thinning.
    How we address this: Hair thinning is often temporary and can be counteracted with specific nutritional supplements and a balanced diet. 


Our priority is ensuring our patients feel heard, understood, and reassured. We address all concerns with transparency, providing thorough education and resources to ensure both their safety and satisfaction throughout the SADI-s journey.

Which Procedures Complement SADI-S?

Following a SADI-s procedure, it's not uncommon for patients to contemplate additional treatments to further refine their new silhouette and address the nuances of their weight loss journey. 

Body contouring options such as tummy tucks, arm lifts, and thigh lifts are increasingly popular for remedying the sagging skin that can accompany dramatic weight loss. Given the impact of weight fluctuations on the chest, treatments like breast lift, breast augmentation, or breast reduction can be pivotal in restoring balance and proportion. 

For those grappling with a pronounced skin apron over the groin area, a panniculectomy becomes a go-to solution. Moreover, as the face mirrors weight changes, procedures like facelifts, neck lifts, or blepharoplasty can be invaluable in regaining a refreshed and youthful visage. To further hone the body's contours, liposuction can target those lingering, stubborn fat pockets. 
Should there be concerns or unsatisfactory results with the initial SADI-s, bariatric revision surgeries might be on the table. Beyond the realm of surgeries, the importance of nutritional and psychological counseling can't be stressed enough, ensuring sustained weight management and emotional well-being. 

As always, before taking any next steps, engaging in insightful consultations with both bariatric and plastic surgery specialists is the key to tailored, optimal post-SADI-s care.
