Biliopancreatic Diversion with Duodenal Switch (BPD/DS)
The Duodenal Switch, or Biliopancreatic Diversion with Duodenal Switch (BPD/DS), is a powerful bariatric and metabolic surgery that combines two methods of popular weight loss procedures; the sleeve gastrectomy and the RNY gastric bypass. The BPD/DS is performed in two stages; restricting the stomach size and rerouting the small bowel.
Duodenal Switch Surgery is a viable option for morbidly obese patients who have significant weight to lose, typically with a BMI of 45+. It is one of the most aggressive obesity treatments among all weight-loss surgical procedures with sustainable long-term weight loss results and reversal of comorbidities.
BPD/DS (and its variations SADi-S and SIPS) is a complex procedure that only a handful of surgeons are capable of. With our leading surgical team, we believe that Mexico Bariatric Center® is the company with more duodenal switch patients across all of America.

How Duodenal Switch Surgery Works
Duodenal Switch (DS) surgery utilizes both restriction and malabsorption mechanisms to yield significant weight loss. This is done by combining aspects of the gastric sleeve and RNY gastric bypass procedures.
Similar to gastric sleeve surgery, 70% of the stomach is removed, bringing about a quicker feeling of fullness and satiety. This also reduces the production of the Grehlin, the hunger hormone. Subsequently, the small intestines are rerouted to decrease the body’s fat absorption by nearly 80% and significantly diminish calorie intake.

Duodenal Switch Weight Loss Timeline
Patients are expected to lose on average 78% of their excess body mass because of two weight-loss components working together. On average patients experience losing 1/2 pound to 1 pound per day for the first 3 months after duodenal switch surgery. Weight loss typically slows down between 6 to 9 months and maximizes at 12 to 18 months postoperatively.
Average Expected Weight Loss1
- 3 months: 35% excess weight loss*
- 6 months: 55% excess weight loss*
- 12 months: 75% excess weight loss*
- 18 months: 80% excess weight loss*
In 2 years by following the proper post-op diet, exercise, and taking bariatric vitamins, patients can shed all of their excess weight. For super-obese patients, skin removal may be needed to reach their ideal weight.

Pros and Cons of Duodenal Switch Surgery
The BPD/DS can yield substantial excess weight loss, in many cases 150 pounds or more. It reduces your stomach’s capacity and detours fat and calorie absorption achieved by intestinal reconfiguration. Extreme weight loss is followed by many years of weight maintenance compared to any other bariatric operation.
An estimated 98% of patients with type II diabetes, 70% of patients with high blood pressure, and 75% of patients with high cholesterol are in remission or even cured after the surgery.[3]
The duodenal switch surgery additionally improves and cures more obesity-related health issues long term, even better than gastric bypass or vertical sleeve gastrectomy. Some of these comorbidities include type 2 diabetes, stroke, high blood pressure, heart disease, sleep apnea, depression, and many more. Another significant benefit of the duodenal switch procedure is the preservation of the pyloric valve – leaving the bile and pancreatic fluid intact. This prevents marginal ulcers and dumping syndrome experienced by patients with Roux-en-Y gastric bypass.
Surgical Steps of the DS Procedure
The Duodenal Switch BPD DS / SADI-s procedures take over 3 hours from start to finish. The operation time depends on the patient’s BMI, pre-op diet, and the surgeon’s skills as well as experience. Patients’ healing is rather fast, and patients can return to work after two to four weeks following the surgery in Mexico. Mexico Bariatric Center keeps the patients 3 nights in the hospital for safer recovery.
These are the specific steps the surgeons use to ensure the highest level of safety and results for patients. After the patient is placed on the surgical table with the face-up and the arms spread apart. This procedure is performed in two stages: First, the gastric volume reduction similar to sleeve gastrectomy to lose weight (about 60 to 80 lbs); Second, rerouting the intestines creates two pathways and a common channel to induce malabsorption and therefore additional weight loss.
The digestive loop is the pathway for food to travel from the stomach to the common channel. The biliopancreatic loop takes bile from the liver and the pancreatic enzymes to the common channel. Food digestion occurs when the switched intestines meet in the common channel. That is where food and digestive juices get mixed before it enters the large intestine.
Duodenal switch is so powerful that 98% of patients with type II diabetes are “cured” after surgery.

Cost of Duodenal Switch Surgery in Mexico
The duodenal switch surgery is the most expensive procedure and far more complicated which only a small percentage of surgeons have the expertise to perform. In the U.S., the duodenal switch out-of-pocket costs are between $24,000 to $32,500.
The cost of duodenal switch surgery in Tijuana, Mexico, however, is considerably less expensive than the U.S. and Canadian counterparts. Mexico Bariatric Center is proud to be one of the few select centers in Mexico to offer duodenal switch surgery starting at $9,600 $6,695.
Single Anastomosis Duodenal Switch (SADi-S)
Single Anastomosis Duodenal Switch (Single Anastomosis Duodeno–ileal Bypass with Sleeve Gastrectomy, SADI-S) is a new type of DS surgery that uses a single anastomosis (reconnection process).
In Single Anastomosis DS, there is only one surgical connection between the stomach and the small intestines, as opposed to two in the classical DS. This new procedure is showing promising results.
+ The total length of the small intestines varies from patient to patient, averaging about 6 meters, or 20 feet long.
Duodenal Switch Surgical Procedure: Open vs. Laparoscopic
Duodenal Switch surgery can be performed open or laparoscopically. In open (traditional) duodenal switch, a long incision is made in the abdomen area. Open bariatric procedures are no longer performed by surgeons in the U.S. and Mexico.
Laparoscopic surgery is a modern surgical technique that helps faster healing, less trauma to the body and fewer complications. In the laparoscopic duodenal switch procedure, also called Minimally Invasive Surgery (MIS), five small incisions are made in the abdomen.
