Single Anastomosis Duodenal Switch

The Single Anastomosis Duodenal Switch has several names. It can be mentioned as the “SADI” or “SADI-S” or “Loop Duodenal Switch”. It is a modification of the standard Duodenal Switch operation. The main difference with this procedure is that a ‘loop’ of intestine is attached to the duodenum instead of a separate limb of intestine. This avoids the need of creating two bowel connections, hence the name “Single Anastomosis”. The SADI was first performed in Europe, then adopted in the US around 2016. We have been performing the operation since January 2019. In October 2019, the ASMBS classified this operation as an Approved Operation.

The SADI has many possible advantages over the traditional Duodenal Switch. Bowel habits tend to be minimally affected. Vitamin and protein deficiency seem to be less of a risk. Risk of internal hernia is less. At the same time, weight loss and metabolic improvement appears to be close to the Duodenal Switch.

The SADI is advantageous over the Gastric Bypass in terms of: (1) greater weight loss and metabolic improvement, (2) less chance of internal hernia, ulcers, and strictures, and (3) less symptoms of dumping syndrome.

We are the first, and only program in the state to offer this operation. It is an excellent option for patients with Type II Diabetes uncontrolled with medication.
