How it works
A duodenal switch combines a gastric sleeve with a bypass of a large part of the small intestine. There are two versions. The traditional duodenal switch (BPD-DS) uses two intestinal connections, and SADI-S uses one. Renew performs SADI-S, not the traditional BPD-DS.
Two versions of the duodenal switch
In 2020 the ASMBS endorsed SADI-S as a modification of the duodenal switch and found that its outcomes did not differ substantially from BPD-DS. It also advised a cautious approach, because long-term data are still limited (ASMBS updated statement on SADI-S, 2020).
| SADI-S | Traditional BPD-DS | |
|---|---|---|
| Intestinal connections | One | Two |
| Operation time | 70 minutes on average in a matched study | 137 minutes in the same study |
| Total weight lost at 5 years | 36.0% in a multicenter study | 42.1% in the same study |
| Short-term complications | 11.6% in the same study | 11.8% |
| Vitamin and mineral levels | Higher vitamin B12, iron, vitamin E and zinc levels | Lower levels of these nutrients |
| At Renew | $6,899, all-inclusive | Not performed. We perform SADI-S instead. |

What to expect
SADI-S leads to lasting weight loss for most patients. Because it reduces how much you absorb, vitamins and follow-up matter more than after a sleeve or gastric bypass.
SADI-S or gastric bypass? SADI-S reduces absorption more than gastric bypass, and it can worsen reflux or cause new reflux (ASMBS). If you have significant reflux, ask about gastric bypass. Dr. Pérez will recommend an option based on your BMI, reflux and health history.
Am I a candidate?
The 2022 ASMBS and IFSO guidelines recommend bariatric surgery for a BMI of 35 or more and say it should be considered for a BMI of 30 to 34.9 with a metabolic condition such as type 2 diabetes. BMI is only one factor, though.
Recommended regardless of obesity-related conditions.
Considered when you have a metabolic condition, such as type 2 diabetes.
The ASMBS calls SADI-S an excellent option after a sleeve when you want more weight loss. Revisions are a custom quote.
The ASMBS describes SADI-S as highly effective for long-term weight loss and type 2 diabetes remission.
You will take supplements and get lab checks for the rest of your life.
SADI-S can make reflux worse, so another surgery may suit you better.

As with other bariatric surgery: bleeding, infection, blood clots, leaks and reactions to anesthesia.
Looser, more frequent bowel movements and more gas.
Vitamins and minerals aren’t absorbed as well as after a sleeve, so supplements are lifelong.
Liquids first, then soft foods, then regular foods in small portions over up to 3 months. Most people return to normal activities within a month.

SADI-S stands for single anastomosis duodeno-ileal bypass with sleeve gastrectomy. It is a version of the duodenal switch that combines a gastric sleeve with one connection between the duodenum and the lower small intestine (ileum).
SADI-S is a type of duodenal switch. The traditional duodenal switch (BPD-DS) uses two intestinal connections, and SADI-S uses one. The ASMBS endorsed SADI-S in 2020 as a modification of the duodenal switch.
SADI-S uses one intestinal connection instead of two and takes less time to perform. The ASMBS found its outcomes did not differ substantially from BPD-DS. In a five-year multicenter study, BPD-DS patients lost somewhat more weight, and SADI-S patients had better vitamin and mineral levels.
SADI-S at Renew Bariatrics is $6,899 all-inclusive, covering your surgeon, anesthesia, pre-op testing, 2 hospital nights, 1 hotel night, transportation, 1 companion, take-home medications and aftercare. Airfare is not included.
