What is SADI Procedure

The SADI (Loop Single Anastomosis Duodenal Ileal Bypass) is a intricate weight-loss surgical procedure that restrains the ability to absorb calories, vitamins and minerals. This procedure is more aggressive and typically recommended to severely obese people who have additional comorbidities. The SADI is a new procedure that is a more simplified version of the duodenal switch. The procedure bypasses about 60-75% of the small intestine and was created in part to help with the side effects seen after a traditional DS.

Weight Loss:

The SADI procedure produces around a loss of about 80% of excess weight and reverses close to 95% of type 2 diabetes cases.

Side Effects & Risks

Side Effects/ Risks:

  • Hernia

Advantages of this procedure:

  • Significant long-term weight loss
  • Lower risk of “dumping syndrome”
  • Significantly helps with resolution of diabetes
  • Only one intestinal anastomosis is made with the SADI instead of two with the DS, which helps to decrease the risk of post-op complications, such as intestinal leakage and also reduces recovery time

There are two components to this procedure:

1. First, the surgeon creates a gastric sleeve.

2. Second, the surgeon divides the intestine a few centimeters past the pylorus. A loop of small intestine is brought up and connected to the stomach. The loop created by the surgeon will allow food to bypass most of the small intestine. Therefore, there will be less absorption of calories.
