SADI-S is Single Anastomosis Duodeno-Ileal Bypass with Sleeve Gastrectomy. It is a modified duodenal switch. The DS is the most powerful weight loss and metabolic surgery in the world. The SADI-S attempts to simplify the procedure. Instead of Y connection between the various parts of the small bowel (which leads to an increased risk of internal hernias) a loop of small intestine is connected to the duodenum.
The surgeon performs a wide sleeve gastrectomy which is followed by end to side duodenal-ileal connection. It is done by sectioning the initial part of the duodenum down to the gastroduodenal artery and then the duodenum is divided with a stapler. After the surgeon identifies the ileo-cecal, junction, he measures it 250 cm upwards and then the loop is raised up antecolically. An end to side anastomosis is created with the duodenal stump. Therefore, the point where the nutrients are absorbed is at the distal small gut that is around 8 feet long.
The core aim of this surgical procedure is to decrease the length of intestine wherein the nutrients are absorbed in the body. This fresh and innovative surgical procedure is targeted for those who are suffering from TypeII Diabetes and severe obesity.
• It has superior results regarding the weight loss
• It is very effective procedure for reducing cholesterol and triglycerides
• It is a successful procedure in reducing the Type II diabetes.
• It also reduces high blood pressure and sleep apnea.
This procedure is not very popular amongst the patients who are looking forward towards the bariatric treatment of obesity. There is one reason for this: most people do not eat enough proteins (read meat) to justify the procedure. Not eating around 120 grams of protein daily may lead to malnutrition. This procedure is preferred by meat eaters who like to eat bigger volumes.It has a shorter operative time and includes only one anastomosis. It is very useful for the prolonged remission of the Type II diabetes. However, long-term results of SADI-S are not yet available, so do factor that in when you discuss your choice with your surgeon.
