What is a SADI?

The SADI procedure is a modification of the traditional Duodenal Switch (BPD-DS), which is the most aggressive bariatric surgery offered.  This procedure requires ONLY one connection or anastomosis.

The first step is still performing a sleeve and removing about 70% of the stomach. The second step requires dividing the duodenum, which is then separated and detached from the stomach.  These combined steps provide a smaller stomach and also metabolic re-balancing to reduce appetite. The intestines are then surgically reconnected by making only ONE connection, so that the digestive enzymes combine with consumed food downstream from the small bowel connection. The reduced absorptive area causes a significant portion of food to pass more quickly into the colon and then to be excreted.

What can I expect from a SADI?

The SADI procedure can be performed laparoscopically (minimally invasive) in most cases. Patients usually go home after 1-2 nights in the hospital and go back to work approximately 2 weeks after surgery.

The percentage of weight loss and improvement in obesity-related medical problems is overall better than with Gastric Sleeve or Gastric Bypass. Results vary from patient to patient, but on average patients can lose 80-100% of excess body weight.  Patients can expect to lose more weight with the SADI.

Long-term bariatric follow-up and long-term supplement intake are important for all bariatric operations, but vitamins are especially important with a SADI. Patients who don’t take the right supplements have a significant risk of medically serious conditions due to vitamin deficiency.

As with all bariatric surgeries, it is important to choose a surgeon at a high-volume program with extensive experience in both surgical technique as well as long-term management and support of patients.
