SINGLE ANASTOMOSIS DUODENAL SWITCH WITH SLEEVE GASTRECTOMY

The Laparoscopic Single Anastomosis Duodenal Switch with Sleeve Gastrectomy (SADI-S) was officially approved by the American Society of Bariatric and Metabolic Surgeons as a primary bariatric weight loss operation in late 2019.  Since then, Dr. Chiasson has embraced this operation as the ideal procedure for both his heaviest patients and those with severe diabetes.  Given his extensive experience with this procedure, he now serves as an Educational Consultant for Ethicon Endo-surgery teaching surgeons from around the country to perform the SADI-S procedure.

What is the Single Anastomosis Duodenal Switch with Sleeve Gastrectomy?

The Single Anastomosis Duodenal Switch with Sleeve Gastrectomy is a Minimally Invasive surgical procedure.  This operation is performed using a laparoscopic technique.  Seven small incisions are made that allow for the placement of a camera and instruments.  Roughly 80% of the stomach is permanently removed with this operation.  In addition, roughly 65% of the small intestines are bypassed.  The operation is the most complex procedure that I offer my patients.

 

How does the Single Anastomosis Duodenal Switch with Sleeve Gastrectomy work?  

The Single Anastomosis Duodenal Switch with Sleeve Gastrectomy works by three different mechanisms.  First, the Sleeve Gastrectomy limits the amount of food that one can eat.  Second, by removing the outer portion of the stomach, the ghrelin hormone is reduced.  This hormone is associated with feeling hunger.  Thus, not only can the patient not eat as much, but they also generally lose their appetite.  Third, less of the nutrients are absorbed due to bypassing the small intestine.

 

What should you expect after Single Anastomosis Duodenal Switch with Sleeve Gastrectomy?

The Single Anastomosis Duodenal Switch with Sleeve Gastrectomy is generally performed as an in-patient procedure for all patients.  The procedure is performed under general anesthesia.  It takes about two hours.  I use the latest pain control techniques to avoid pain following surgery.  In general, roughly 50% of patients are discharged the morning following their surgery.  The remainder are generally discharged the following day.  Despite having a more complex operation, our patients often have very little discomfort. The majority of patients return to normal activities and work within a few weeks.

 

Advantages of the Single Anastomosis Duodenal Switch with Sleeve Gastrectomy?

The Single Anastomosis Duodenal Switch with Sleeve Gastrectomy is the best weight loss operation for my heaviest patients and those with severe metabolic syndrome.  Thus, it has a significant impact on the associated medical conditions such as high blood pressure, hyperlipidemia, Fatty Liver Disease, type II diabetes, and coronary artery disease. 

 

How much weight loss is associated with the Single Anastomosis Duodenal Switch with Sleeve Gastrectomy?

The Single Anastomosis Duodenal Switch with Sleeve Gastrectomy has been extensively evaluated.  On average, patients who have this procedure will lose about 40-45% of their total body weight.
