(Single Anastomosis Duodeno-Ileal Bypass with Sleeve)
The SADI-S is a restrictive and malabsorptive operation typically reserved
for patients with severe obesity or obesity-related illnesses. This means
we will surgically restrict the amount of food you can ingest. We will
significantly bypass the small intestine so fewer calories are absorbed.
This results in significant weight loss, but also an increased risk of
nutritional deficiencies.
The operation begins with the restrictive portion of the procedure. Using
a surgical stapler, the surgeon divides the stomach into two parts, the
“sleeve” and the “remaining stomach.” The sleeve
is your new stomach and is about the size of a banana. The new and smaller
stomach will restrict the amount of food that can be eaten. The remaining
stomach will be removed and discarded during the surgery.
Next, the surgeon will perform the malabsorptive portion of the procedure.
The surgeon will divide the first part of the small intestine just below
the stomach. Then the surgeon will measure a few feet from the end of
the small intestine and connect this part of the small intestine to the
stomach. The SADI-S bypasses a sizable portion of the small intestine,
creating considerable malabsorption.
Food will travel from the mouth into the sleeve. Since the new sleeve is
small, you should feel full sooner than you had in the past. The food
will then continue into the intestine, and digestion will occur.
After a SADI-S, you can expect to stay 2–3 nights in the hospital.
You will also need to follow a special diet to allow for healing and to
avoid complications. In about two months, most patients return to a regular
healthy eating plan. Because the new sleeve is so small and a sizable
portion of the intestine has been bypassed, certain vitamins and minerals
can no longer be absorbed like they once were. Therefore, vitamin and
mineral supplements are essential for the rest of your life.
