SADI-S Procedure for Weight Loss

Learn about the SADI-S procedure offered at Vital Surgical Specialists. This minimally invasive surgery helps patients achieve significant weight loss and better manage diabetes.

SADI-S Surgery at Vital Surgical Specialists

Weight loss surgery has evolved significantly over the years, providing patients with more effective and safer options. One such advancement is the SADI-S (Single Anastomosis Duodenal-Ileal bypass with Sleeve Gastrectomy) procedure, a modified version of the traditional duodenal switch surgery. Vital Surgical Specialists is proud to offer this innovative procedure, helping patients achieve their weight loss and health goals with reduced risks and improved outcomes.

Studies show that two years post-SADI-S surgery, patients can lose over 95% of their excess weight, with more than 90% achieving complete remission of diabetes. While long-term data beyond four years is limited, current results indicate that the SADI-S procedure offers similar benefits to the traditional duodenal switch without many of its long-term complications.

What is SADI-S Surgery?

The SADI-S procedure, also known as the modified duodenal switch, loop DS, or SIPS (Single Anastomosis Loop Duodeno-Ileal Bypass with Sleeve Gastrectomy), represents a less invasive approach to weight loss surgery. Unlike the traditional duodenal switch that involves two connections, the SADI-S features a single connection in a loop configuration, simplifying the procedure and reducing associated risks.

The Modified Duodenal Switch

Faster Surgery and Reduced Risk

By creating a single intestinal connection instead of two, the SADI-S surgery is quicker to perform and carries a lower risk of leaks and complications. This design also bypasses only about 50% of the small intestine, compared to the 85-90% bypass in the traditional duodenal switch. Consequently, this approach significantly reduces the chances of malnutrition and chronic diarrhea, which were common issues with the other procedures.

Commitment to Health and Well-being

The SADI-S procedure is a safe and effective option for weight loss and diabetes management. However, it requires a lifelong commitment to taking vitamins and protein supplements. With dedication to a healthy diet and supplementation, patients can enjoy significant health benefits and enhanced quality of life.

Comparing SADI-S to Roux-en-Y Gastric Bypass

The SADI-S procedure offers several benefits over gastric bypass surgery (RYGB), including:

  • Patients can safely take aspirin, NSAIDs, and steroids without the risk of developing marginal ulcers.

  • It is the most effective surgery for diabetes management.

  • It facilitates the greatest weight loss among bariatric procedures.

  • There is a decreased risk of bowel obstructions compared to both traditional DS and RYGB.

How Does SADI-S Surgery Work?

A Dual Approach: Restrictive and Malabsorptive

Like the gastric bypass, the SADI-S procedure combines restrictive and malabsorptive techniques. The stomach is reduced in size to limit food intake (restrictive), and a portion of the small intestine is bypassed to decrease nutrient absorption (malabsorptive). This dual approach makes SADI-S highly effective for sustained weight loss.

SADI-S Surgical Process

Step-by-Step Surgical Process

  1. Sleeve Gastrectomy

    About 80% of the stomach is removed, creating a sleeve-like structure. This limits food intake and induces early satiety.

  2. Intestinal Bypass

    The first portion of the small intestine (duodenum) is divided, and a loop of the small intestine is attached to the duodenum, bypassing roughly half of the small intestine. This limits calorie and fat absorption.

  3. Hospital Stay and Recovery

    The SADI-S procedure typically takes 60-90 minutes, depending on individual factors such as surgical history and anatomy. It is usually performed laparoscopically through small incisions, resulting in a shorter hospital stay, faster recovery, minimal scarring, and less pain. Most patients stay in the hospital for just one night.

Who is a Good Candidate for SADI-S?

Ideal candidates for the SADI-S surgery include individuals who:

  • Have significant weight to lose.

  • Seek the best chance of curing type II diabetes (up to 98% success rate).

  • Are committed to lifelong vitamin and supplement intake.

  • Need to use NSAIDs or steroids.

  • Have a history of smoking or nicotine use.

  • In Canada, there are public options and a few private avenues that are not aways well known to patients and referring doctors. Generally, the public system requires a referral from your primary care provider to a surgeon. There can be a wait to see the primary care provider, a wait to see the surgeon, and then often a long wait to have the surgery. Many Canadians struggle to gain access to surgery due to the long wait times and the lack of a primary care provider to start the process.

    The Canada Health Act prohibits patients from paying for medically necessary care. Physicians that are part of a provincial healthcare insurance plan cannot charge patients for medically necessary care in that province. It is currently possible to have a surgeon from another province perform the surgery and pay the costs of the surgeon, anesthesia, nursing, and related procedure costs directly. It is, therefore, possible to travel to another province within Canada or to another country for private care. Another option is to find a surgeon that has opted out of the public system and can provide private care in your home province. This, of course, is the ideal private avenue as it precludes the need for patients to travel. At Vital, these are the scenarios we try to create for patients.

  • For most people it is about timely access to care. Many of our patients also appreciate a more premium service that caters to their health, personal priorities, and convenience. Some patients don’t like the hospital setting and prefer a higher level of privacy, discretion, and individual consideration. In the private context it is possible to deliver care with more attention to the patient experience pursuing excellence with each patient rather than trying to do as many surgeries as possible with limited resources.

  • Yes, we work with a few financing partners. Many patients simply do the math and see that the income they will lose from lost work while waiting for care in the public system exceeds the cost of the surgery itself. Others value their time and health enough to accept the cost of not waiting. Our financing options can make private surgery accessible to almost any budget. Patients can have the flexibility to pay over a short or long term and finance whatever portion of the surgery they wish.

  • Different provinces have different interpretations of the Canada Health Act. There are differences in terms of what each province deems “medically necessary” and differences in what types of surgery each provincial College permits in private surgical centres. This leads to a shifting landscape and it is always best to check with us to understand how the system works and what options you may have. We are here to help and will always try to direct you to your best option whether it be public or private. Vital is a 100% physician owned company and is duty bound to put patient interests first.

    For BC patients:

    Our surgeons work closely with the Cambie clinic to provide private general surgical services to BC residents in Vancouver. The major advantage to patients is that we come to them instead of making them travel.

    For Alberta Patients:

    You can meet with your surgeon at our clinic in Calgary. We can plan your surgery and deliver your follow up care close to home. We do not charge Alberta patients for consults or follow up appointments as these are publicly insured. We are currently offering private general surgery (hernias, endoscopy, gallbladder removals, and more) for Albertans in Vancouver with Dr. Sean Gregg. If there is sufficient interest, we will start offering private general surgery services in Alberta for Albertans in the second half of 2024. Don’t hesitate to contact us with questions about this program.

    For patients elsewhere in Canada or the US we are able to offer services in Calgary, Vancouver, or Montreal depending on the surgery required and the preference of the patient.
