Single Anastomosis Duodeno-Ileostomy (SADI)


The Single Anastomosis Duodeno-Ileostomy, or SADI, is only recommended as part of an investigational or experimental protocol.

It is often referred to as a simpler version of the Biliary Pancreatic Diversion with Duodenal Switch procedure. 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.

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.

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.
