What is Single Anastomosis Duodenal-Ileal Bypass?
Single Anastomosis Duodenal-Ileal Bypass or sometimes referred to as SADI Bypass or SADI-S (Single Anastomosis Duodenal Ileal bypass with sleeve) is basically an upgraded version of the Duodenal Switch Surgery.
It combines both restrictive and malabsorptive measures, which offers significant weight loss potential. It is often used for very obese individuals because it offers one of the most aggressive weight loss results provided by Bariatric Surgery.
The American Society for Metabolic and Bariatric Surgery has recently changed SADI to an approved weight loss surgery from its previous category of investigational. This procedure involves a combination of Gastric Sleeve with an aggressive Gastric Bypass of the small intestine. Unlike the duodenal switch, which consists of two intestinal bypass routes, the SADI surgery only contains one which reduces the time in surgery as well as risks.
How does SADI Bypass work?
SADI surgery can be combined into one surgical procedure or two separate surgeries depending on the patient. Patients that are very obese often benefit from having the first stage of surgery and then waiting several months until they have the second stage of the surgery. This allows the patient time to lose a substantial amount of weight between surgeries which lowers risk factors.
- The first stage of the surgery is gastric sleeve surgery which significantly reduces the size of the stomach. Using a laparoscopy the surgeon accesses the stomach via several small abdominal incisions and removes about 80-85% of the lower portion of the stomach leaving it resembling a small banana. The smaller stomach will help the patient with portion control going forward and also reduce the production of the hormone ghrelin which sends hunger signals to the body.
- The second stage of the surgery takes a portion of our small intestine and re-routes it to bypass about 3/4 of the digestive system. This significantly restricts the number of calories that the body can absorb from any food ingested. This also restricts the absorption of vitamins and nutrients that the body critically needs to remain healthy and function so daily supplements will be critical after SADI surgery.
Why consider Single Anastomosis Duodenal-Ileal Bypass?
- Uses only one bypass.
- Reduced risk for complications.
- Reduced risk of dumping syndrome.
- Yields significant weight-loss results.
- Proven to reduce or eliminate type 2 diabetes.
- Alleviates many obesity-related comorbidities.
- Can be used to modify an existing bariatric surgery for additional weight loss or address weight regain.
How much Weight can I lose with SADI?
- The weight loss after SADI surgery tends to be rapid and significant.
- After SADI surgery, patients can lose between 80-90% or more of their excess weight between a year and eighteen months post-surgery.
- The first 3 months immediately after surgery patients will see the most weight loss.
- The closest comparison in bariatric procedures would be to a gastric sleeve or gastric bypass, which offers a loss of 65-85% of excess weight.
Who is a Candidate for SADI?
Are there any Risks Associated with SADI?
Any type of surgery involves some risks. With SADI surgery, risks may include:
SADI is non-reversible.
SADI is an excellent surgery for some individuals but is aggressive, so it may not be for everyone. To learn more about SADI surgery or find out which weight loss surgery would be best for you, please call us today to set up a consultation.
At IBI HealthCare Institute, we offer both surgical and non-surgical weight loss procedures and would be happy to help guide you as you navigate through the topic of bariatric weight loss.
How long will the Results last?
The results of SADI surgery are expected to be long-lasting based on the patient following and committing to a new lifestyle, including diet and exercise.
It is also important that patients who have SADI surgery remain faithful in taking all their additional supplements.
This will ensure they remain healthy and can maintain their weight loss results. Patients who utilize their support systems to the fullest are known to have the best results.
When will I start seeing Results?
Patients who have SADI surgery see dramatic results in the first 3 months. In addition to rapid weight loss, many patients have experienced their obesity-related health issues like type 2 diabetes going into remission, no longer requiring medication.
The amount of weight loss and associated timeline will be greatly influenced by the patient’s willingness to follow all postoperative dietary restrictions and exercise programs. Usually, 12 months after surgery patients have reached or are very close to their target weight.
