What is the Single Anastomosis Duodenal Switch? SADI / SIPS Procedure

Deciding which bariatric surgery is right for you is a task that you and your surgeon take very seriously. One procedure to you might consider is the Single Anastomosis Duodenal Switch (abbreviated SADI or SIPS).

Keep reading to learn how this surgery differs from similar weight loss surgeries.

What is a SADI / SIPS Procedure?

Essentially, the goals of bariatric surgery are two fold—to restrict the amount of food you can consume and to reduce the amount of nutrients you absorb.

The Single Anastamosis Duodenal Switch procedure accomplishes both of these goals.

This procedure resembles the standard duodenal switch very closely. Unlike the standard procedure, the single anastomosis duodenal switch procedure transects the intestine at only one point.

This is why the procedure is called a “single.” Just like the standard procedure, your surgeon removes a great portion of your stomach leaving a sleeve.

The amount of food that your stomach can hold will decrease from a quart to about 4-6 ounces. You surgeon will preserve the antrum, this pushes the food through the bottom valve of your stomach.

Likewise, this procedure preserves the pylorus and the nerves that control the stomach. The pylorus is the opening from the stomach into the duodenum.

Thus, the stomach is much smaller but functions essentially like a normal stomach.

Most patients enjoy a relatively normal diet without experiencing the “dumping” syndrome that other bariatric surgeries can cause.

How Does the Single Anastamosis Duodenal Switch Work?

Your stomach function remains mostly the same and half of the small intestine is bypassed. The result is that you will need to eat less food to feel full, and you will absorb fewer calories.

In removing most of your stomach, the procedure reduces the amount of food you can consume eat each meal.single anastomosis duodenal switch

Importantly, removing this part of your stomach affects the area that is responsible for secreting a hormone, ghrelin, that causes you to feel hungry.

Similarly, the loop created by your surgeon allows the food to bypass the top half of the small intestine. This means that the calories and nutrients you can absorb are greatly reduced.

In addition to this, your food lands in the part of your intestine that secretes hunger-reducing hormones quicker. Resulting in a diminished appetite.

All of these factors work to accomplish your weight loss goals.

Studies continue to show that the SIPS procedure is successful. In addition to losing weight, many patients see a vast improvement in their obesity-related conditions, such as Type 2 diabetes, high blood pressure, obstructive sleep apnea, and high cholesterol.

Advantages and Disadvantages of SADI / SIPS Procedure

The Single Anastamosis Duodenal Switch has many advantages, including:

  • Significant weight loss
  • More “normal” diet
  • Low risk of “dumping syndrome”
  • Higher tolerance of medications like aspirin, NSAIDS, etc.
  • Improvement of obesity-related conditions like Type 2 Diabetes
  • Less risk of complications since there’s only one anastomosis (like obstruction, ulcers, etc.)

Some disadvantages of this procedure are:

  • Patients need to be monitored for protein malnutrition, anemia and bone disease for the rest of their lives. Vitamin supplementation is mandatory.
  • Relatively new surgery, so it hasn’t been studied as long as other procedures.
