Single anastomosis duodeno-ileal bypass (SADI)
SADI is a surgery that usually complements the vertical gastrectomy and is done in a second stage. We are talking about a hypoabsorptive surgery. Food will no longer pass through a certain part of the small intestine. There will be about 250 cm left where food can be absorbed. This surgery can be performed in people whose body mass index (BMI) is higher than 50 to begin with or if the associated health problems (diabetes, hypertension, etc.) are important and severe.
The distinctive feature of this procedure is that there is only one anastomosis (connection) and the pylorus is preserved. This can decrease surgical complications and improve comfort after the operation. There is no dumping syndrome with this procedure.
The surgery will take approximately 2 hours.
This is surgery that is performed by laparoscopy (5 or 6 small 1 to 3 cm incisions in the abdomen).
The usual length of hospital stay after surgery is between 24 and 48 hours depending on the health condition.
This surgery can be performed at the same time as the vertical gastrectomy for some patients. (SADI-S)

Complications are rare. To decrease the risk of complications and side effects, it is important to follow the indications and recommendations. It is strongly recommended that you do not smoke, do not drink while eating, limit alcohol consumption and significantly reduce your sugary food intake. Surgery is an effective tool that allows you to lose, on average, 50-60% of excess weight. It will help improve or eliminate many associated health problems (diabetes, hypertension, etc.). You will have better results if this is combined with good eating habits and a varied physical activities program. Taking vitamins and supplements will be necessary after surgery to prevent certain nutritional deficiencies.
