SADI-S

SINGLE-ANASTOMOSIS DUODENAL BYPASS WITH SLEEVE GASTRECTOMY (SADI-S)

We will start by describing the SADI-S as it is basically a simplified version of the DS. While similar to the DS, the SADI-S is simpler and takes less time to perform as there is only one surgical bowel connection. To start the operation a sleeve gastrectomy is performed, making a smaller tube-shaped stomach. The first part of the small intestine is divided just after the stomach. A loop of intestine is measured 9-10 feet from its end and is then connected to the stomach. This is the only intestinal connection performed in this procedure. When the patient eats, food goes through the pouch and directly into the latter portion of the small intestine. At this point the food mixes with digestive juices from the first part of the small intestine. This allows enough absorption of calories, vitamins and minerals to maintain healthy levels of nutrition. This surgery offers good weight loss along with less hunger, more fullness, blood sugar control and diabetes improvement.

Benefits

• Highly effective for long-term weight loss and remission of type 2 diabetes.
• Simpler and faster to perform (one intestinal connection) than BPD-DS.
• Excellent option for a patient who already had a sleeve gastrectomy and is seeking further weight loss.

Risks

• Rare complications include infection, hernias, ulcers, or bleeding. 
• Over time, some vitamin & minerals may not be well absorbed. It is imperative to follow post-operative guidelines and take the appropriate nutritional supplements to avoid serious health conditions. 
• It is important that you do not take any NSAID medications such as aspirin, ibuprofen, Aleve, Excedrin or Motrin. These medications can cause ulcers. 
• Not all calories are absorbed particularly fat, so the patient has to follow the dietary recommendations or may have increased gas and loose stool. 
• It has only been performed since 2008 regularly so doesn’t have as long term results as the other procedures.
• Can result in new reflux symptoms or can worsen them in 1 out of 10 patients.

Expected Weight Loss After a Bypass 

• You can expect to lose up to 70-85% of excess body weight.
