What is Duodenal Switch Surgery?

How Duodenal Switch Surgery Works

The duodenal switch procedure works by creating a smaller stomach pouch by removing a portion of the stomach, limiting the amount of food you can eat at one time. This restrictive aspect helps control your food intake and promotes satiety with smaller portions.

The other aspect of the surgery involves rerouting a section of the small intestine, allowing food to bypass a significant portion of the digestive tract. As a result, fewer calories and nutrients are absorbed from the food you consume, leading to additional weight loss.

In recent years, the BPD-DS procedure has seen an evolution, with the emergence of a modified technique known as SADI-S (Single Anastomosis Duodeno-Ileal Bypass with Sleeve Gastrectomy), also referred to as the Loop Duodenal Switch.

SADI-S is the most commonly performed variation of the traditional duodenal switch surgery. In this modified procedure, the surgeon creates a single anastomosis, bypassing a portion of the small intestine and connecting the duodenum to the ileum. By streamlining the surgical process, SADI-S offers potential benefits such as reduced operative time and improved surgical outcomes. As with any surgical decision, the choice of the BPD-DS procedure, whether traditional or SADI-S, should be thoroughly discussed and evaluated with Dr. Beltre to determine the most appropriate option for you based on your unique needs and medical condition.

The Duodenal Switch Procedure

The duodenal switch procedure is an outpatient bariatric surgery performed under general anesthesia and comprises two stages: the sleeve gastrectomy and the intestinal switch. The initial sleeve gastrectomy stage involves reducing the stomach’s size to promote weight loss. Then, the intestinal switch is performed to reroute the small intestine and create the malabsorptive component of the procedure.

Duodenal switch surgery can be performed using minimally invasive laparoscopic technique. Beltre Bariatrics uses the less invasive laparoscopic method, involving small “keyhole” incisions and the use of small tools to access the surgical site. This results in reduced scarring and faster recovery compared to open surgery.
