Single Anastomosis Duodeno-ileostomy with Sleeve (SADI-S), also known as SADI-S is the newest weight loss procedure. SADI-S is a modification of the traditional duodenal switch (DS), bypassing less of the intestines. The procedure combines a sleeved stomach and attaches a medium-length bypass. Weight loss is 75% of excess weight and the absorption of vitamins and protein after surgery improved.

Single Anastomosis Duodeno-ileostomy with Sleeve can be compared to a Duodenal Switch procedure, but SADI-S only has a single connection with the small intestine. Since it involves a longer common channel, this reduces the risk of malabsorption.

SADI-S lessens the appetite and the small intestine’s ability to absorb calories. It also improves metabolic hormones and health conditions.

Ideal Candidates

The best candidates for Single Anastomosis Duodeno-ileostomy with Sleeve are those battling morbid obesity. It is ideal for those who want a better weight-loss method than a gastric bypass and sleeve.

Among its benefits are better long-term weight loss, diabetes treatment, lower chance of weight regain, less acid reflux, and reduced risk of stomach ulcer than those provided by bypass and sleeve.

Single Anastomosis Duodeno-Ileostomy with Sleeve Consultation

At your consultation with our bariatric specialists, you may need to bring imaging or lab results required by our doctors to gauge suitability for the procedure. You also need to be mentally prepared before deciding to go through with the surgery or not.

The consultation is meant to prepare you for your responsibilities after the SADI-S, including post-surgery care and lifestyle changes. Don’t hesitate to ask questions or discuss your concerns about the surgery.

The Procedure

First, the bariatric specialist will perform a sleeve gastrectomy, removing a large part of the stomach and modifying the shape of the remaining part. The doctor then separates the duodenum from the pylorus before the ileum is connected to the duodenum.

SADI-S distinguishes itself from other duodenal switch procedures because it only involves one anastomosis instead of the usual two. It directs nutrients through a single loop, which reduces the chance of vitamin deficiency and diarrhea.

The Recovery Process

You only need to spend an hour on the table while the specialist performs the Single Anastomosis Duodeno-ileostomy with Sleeve. Patients often only need a night or two at the hospital. They can return to their regular routines after 2-4 weeks.
