SADI Bariatric Surgery in Knoxville, TN

The Single Anastomosis Duodeno-Ileostomy, or SADI, is the most recent weight loss procedure to be endorsed by the American Society for Metabolic and Bariatric Surgery (ASMBS).

It is often referred to as a simpler version of the Biliary Pancreatic Diversion with Duodenal Switch procedure that includes only one bowel connection. The latter treatment has proven to be a very effective surgical weight loss option for many patients; however, the procedure is known for its complexity.

Advantages

According to the ASMBS, some of the advantages & disadvantages of SADI include:

  • Effective for long-term weight loss and improvement or resolutions of Type 2 Diabetes
  • Faster and more simple to perform than gastric bypass or BPD-DS procedures.
  • Excellent option for those who have previously had a sleeve gastrectomy and are seeking increased weight loss

Disadvantages

  • Vitamins and mineral absorption is less than with the sleeve gastrectomy
  • Newer procedure without long-term outcome data
  • Can worsen or prompt the development of acid reflux
  • Potential for looser and increased bowel movements

Dr. Williams explains the differences between the BPD/DS (Biliary Pancreatic Diversion with Duodenal Switch) and the SADI (Single Anastomosis Duodeno-Ilesotmy procedures.

Procedure

There are two stages to this particular procedure: first, a sleeve gastrectomy will be performed, which will remove a significant portion of the stomach and reshape the remaining portion. After this stage, the duodenum is separated beyond the pylorus and the lower portion of the intestine (ileum) is anastomosed (connected) to the duodenum.

The main difference between SADI and other types of duodenal switch operations is that there is only one anastomosis as opposed to two. This allows nutrients to pass through one common loop, which may result in less fat soluble vitamin deficiencies and fewer possible side effects such as diarrhea.

The SADI procedure offers good weight loss as well as less hunger, increased fullness, blood sugar control and diabetes improvement or resolution.

Recovery

The SADI surgery typically takes only about an hour to complete and many patients often need to spend no more than one or two nights in the hospital. Most individuals are able to return to normal daily routines after approximately two to four weeks.

Many patients who undergo SADI procedure lose significant amounts of weight and reduce serious risks to their overall health.

SADI Surgery FAQs

What is the SADI weight loss procedure?

SADI, or Single Anastomosis Duodeno-Ileostomy, is a modern bariatric surgery that combines a sleeve gastrectomy with a single-loop intestinal bypass. It is the most recent weight loss procedure endorsed by the American Society for Metabolic and Bariatric Surgery (ASMBS) as an effective metabolic treatment.

How much weight can patients expect to lose with SADI?

Many patients experience significant and sustained weight loss following SADI by combining stomach restriction with calorie malabsorption. In addition to weight loss, the procedure offers powerful blood sugar control and high rates of diabetes improvement or resolution.

What are the main health benefits of SADI surgery?

Beyond substantial weight loss, SADI is highly effective at resolving obesity-related conditions, particularly Type 2 Diabetes. Patients also benefit from increased feelings of fullness and decreased hunger due to the hormonal changes triggered by the surgery.

Is SADI a restrictive or malabsorptive procedure?

SADI is both; it is restrictive because the sleeve gastrectomy reduces the stomach’s size to limit food intake, and it is malabsorptive because the intestinal bypass shortens the path food travels. This combination allows for rapid weight loss and significant metabolic improvements.

What is the recovery time for SADI surgery?

The surgery typically takes about one hour to complete, and most patients spend just one or two nights in the hospital. Most individuals can return to their normal daily routines and sedentary work within approximately two to four weeks.
