What is Single Anastomosis Duodenal Switch (SADI)?
Despite the fact that it results in significant weight loss, Duodenal switch surgery (DS) is less commonly known than gastric sleeve or gastric bypass, which may be in part because it is a more complex surgery. Additionally, the traditional approach to duodenal switch, also called biliopancreatic diversion with duodenal switch, sometimes resulted in unfavorable side effects. However, Single Anastomosis Duodenal Switch, sometimes called SADI-S or “Loop DS” is a safer, more modern approach to duodenal switch surgery that minimizes the risk of

complications.
During duodenal switch surgery, a portion of the stomach is removed, similar to a sleeve gastrectomy procedure. Then, the surgeon divides the duodenum, which is part of the small intestine, and reroutes it to the lower intestine. The main difference between SADI and traditional DS surgery, is that the intestines are rerouted at a single connection spot instead of two connection spots.
How Does Duodenal Switch Work?
Single Anastomosis Duodenal Switch surgery promotes weight loss in three ways:
- Restriction: the size of the stomach is reduced to limit the amount of food you can eat
- Malabsorption: The digestive system is rerouted so that fewer calories are absorbed in the intestine
- Hormonal: the body’s production of ghrelin, the “hunger hormone” is reduced so you feel fewer food cravings
Am I a Good Candidate for Bariatric Surgery?
A bariatric procedure may be right for you if you have tried to lose weight through diet and exercise, but your efforts have been unsuccessful or you have not been able to maintain long-term weight loss. While, in general, bariatric surgery candidates have a body mass index (BMI) higher than 40 or a BMI of 35 or more along with obesity-related medical conditions, duodenal switch surgery is often reserved for patients with a BMI above 50. One thing that all candidates have in common is a willingness to commit to new habits and a healthier lifestyle. The experts at NWWC can explain your options and help determine the best weight loss procedure for you.

What to Expect From Duodenal Switch Surgery
Preparing for Duodenal Switch Surgery
The first step is to schedule a consultation appointment with one of our bariatric surgeons. We will review your medical history, discuss your goals, and examine you in order to determine if you are a candidate. If duodenal switch surgery is right for you, we will give you detailed pre-surgical instructions.
Your Duodenal Switch Surgery
We perform most of our bariatric procedures at Sound Surgeons, which is our specialized and fully accredited surgical center. Our surgeons use laparoscopic techniques, so you will have smaller incisions and an easier recovery. Duodenal switch surgery is typically an outpatient procedure performed with general anesthesia.
Recovery After Duodenal Switch Surgery
We will schedule follow-up appointments to monitor your progress and healing after your duodenal switch procedure. You will need to take at least one full week off of work and you will need to refrain from strenuous activities for several weeks. We will advise you on lifestyle changes and you’ll receive support from our dietitian on your post-procedure diet. Since duodenal switch is a malabsorptive procedure, we may also recommend dietary supplementation to ensure you get the calcium, vitamins and nutrients you need.

Frequently Asked Questions About Duodenal Switch Surgery
Will insurance cover duodenal switch surgery?
Many insurance plans offer coverage for patients who are candidates for duodenal switch. Contact our insurance verification team to learn more.
What is the difference between gastric bypass and duodenal switch?
Both duodenal switch and gastric bypass, also known as roux-en-y gastric bypass, are effective weight loss surgeries. The primary difference is that in a gastric bypass procedure, the intestines are rerouted, leaving a small gastric pouch for food; in a duodenal switch procedure, a portion of the stomach is removed and the intestines are rerouted. A DS procedure is sometimes compared to having both a gastric sleeve and gastric bypass together.
What are the potential risks of duodenal switch surgery?
Any surgical procedure carries some risk of side effects or complications. You can minimize your risks by choosing an experienced, board-certified surgeon and following all post-surgery instructions. The most common risks of duodenal switch surgery include bleeding, infection or anesthesia risks during surgery. Many long-term risks, such as “dumping syndrome” are significantly reduced with the SADI approach.
