(SADI-S / SIPS)

Loop Duodenal Switch

The Loop-Duodenal Switch (SADI-S / SIPS) is a combination of two procedures. First, a sleeve gastrectomy is performed. A joint is then created just below the sleeve gastrectomy, and a significant portion of the small bowel is bypassed. This procedure is effective for weight loss as it is both restrictive and malabsorptive.

Why consider a single anastomosis gastric bypass & key considerations

Minimally invasive surgical technique

Improve chronic disease conditions such as pre-diabetes, high blood pressure and cholesterol

Can help to improve fertility for both females and males

Improve mental health

How is a Loop-Duodenal Switch (SADI-S / SIPS) Performed?

General Anesthesia

You are placed under general anesthesia for a safe and pain-free surgical experience.

Laparoscopic Access

Several small incisions are made in the abdomen.

A laparoscope and surgical instruments are inserted to perform the surgery minimally invasively.

Sleeve Gastrectomy

The first part of the procedure is identical to a gastric sleeve: a large portion of the stomach is removed, leaving a narrow, tube-shaped stomach.

This restricts food intake and reduces hunger hormones (like ghrelin).

Duodenal Division

The first part of the small intestine (the duodenum, just past the stomach) is divided.

Unlike Roux-en-Y, the pyloric valve (which regulates stomach emptying) is preserved, improving digestion and reducing dumping syndrome.

Intestinal Bypass

A loop of the lower small intestine is brought up and connected to the newly divided duodenum.

This bypasses a large portion of the small intestine, reducing calorie and nutrient absorption.

Leak Test and Closure

The connection (anastomosis) is tested for leaks, and the incisions are closed with sutures or staples.
