Duodenal Switch vs. SADI: A Weight Loss Surgery Guide

Duodenal Switch vs SADI

Learn about the techniques and procedures involved in both the duodenal switch vs SADI, including how they function and what makes them different.

Duodenal Switch vs SADI

Both types of bariatric surgeries are designed to aid higher-weight patients in achieving significant weight loss. Additionally, obesity frequently causes co-morbidities such as type 2 diabetes and high blood pressure, which are directly associated with excessive weight.

Moreover, SADI-S, also known as stomach intestinal pylorus sparing surgery (SIPS), is a modified version of the duodenal switch procedure. Finally, to gain a comprehensive understanding of the disparities between these two surgeries, let’s delve deeper into each one.

History of Duodenal Switch Surgery

Duodenal Switch was developed as an improvement on a surgery called biliopancreatic diversion (BPD) so you may see a duodenal switch referred to as DS or DS-BPD.

The biliopancreatic diversion surgery divides the patient’s stomach horizontally, rerouting a section of the digestive system. As a result, this bypassed portion, which is lengthy, often leads to malnutrition and dumping syndrome. Additionally, dumping syndrome symptoms may occur within 10 minutes to 3 hours after eating.

The duodenal switch was created to alleviate the negative side effects of the biliopancreatic diversion.

What is Duodenal Switch Surgery?

The duodenal switch is an improved version of the biliopancreatic diversion. It reduces the stomach by 75% and shapes it into a small sleeve-like pouch, similar to the gastric sleeve. This smaller stomach sleeve limits the amount of food intake and improves digestion. As a result, the duodenal switch minimizes dumping and malnutrition side effects.

Surgeons sometimes perform duodenal surgery in two different steps and break it up into two different surgeries to reduce the risks involved and shorten the surgical time.

  • Step 1 is gastric sleeve surgery (VSG or LGS) to reduce the size of the stomach and then after 2-3 months.

  • The second surgery, Step 2, alters the digestive system to shorten the time food stays in the digestive tract and prevent the body from absorbing all the calories.

At IBI Healthcare Institute, you can perform the two steps at the same time, with no wait time and no additional surgery.

The duodenal switch historically achieved substantial weight loss and resolved obesity-related health problems. However, a new variation called SADI-S has been developed due to the complexity, length, and risks associated with it. Moreover, SADI-S offers a modified approach to achieve similar results.

What Is SADI-S Surgery?

To better understand the Single Anastomosis Duodenal-ileal Bypass with Sleeve Gastrectomy (SADI-S) also called single anastomosis duodenal ileostomy, we will break down a few of the medical terms within the title.

What Is An Anastomosis?

Anastomosis refers to the joining of two sections of the intestines or the stomach and intestine, either through stapling or stitching. However, surgical connections between the spliced intestine or intestines and the stomach pose a risk of leakage.

What Does Duodenal-ileal Mean?

The duodenal-ileal term refers to the connection between the duodenum, the first part of the intestine, and the ileum, the lower portion of the intestine.

SADI-S surgery involves performing gastric sleeve surgery followed by bypassing a portion of the digestive tract. Additionally, this procedure, unlike the DS, only requires one surgical connection and modifies a single section of the intestine using a loop.

The duodenal switch contains 2 anastomoses with a Y-shape alteration to the intestines.

SADI-S reduces potential risks by having only one anastomosis and one digestive tract alteration, minimizing the chance of leaking. The surgery takes less time to perform than a duodenal switch or a gastric bypass.

Duodenal Switch vs SADI: Similarities

Surgeons perform the majority of SADI-S and duodenal switch surgeries laparoscopically and can complete them in two steps if necessary. These surgeries start with a standard sleeve gastrectomy surgery (VSG, LSG, or GS) to control patients’ appetites and prevent overeating.

 High-risk individuals can benefit from a staged approach that begins with the sleeve gastrectomy for initial weight loss, followed by the bypass. If required, surgeons can easily convert a sleeve gastrectomy to a duodenal switch or SADI-S surgery.

Duodenal Switch vs SADI: Differences

The biggest difference between the two procedures is that the duodenal switch alters more of the intestinal tract and splits a portion into a Y formation. It also has two anastomoses posing more risk for post-surgical leaking and is more malabsorptive which can cause malnutrition. Duodenal switch surgery is more complicated and poses more long-term risks.

The SADI-S procedure minimizes risks of leaks or intestinal blockages with its single anastomosis and loop-shaped intestinal alteration. SADI-S is a safer alternative to the duodenal switch as it does not divide the bowels, reducing the risk.

Benefits of Both Duodenal Switch and SADI-S

  • Patients achieve significant weight loss.

  • Feel full longer.

  • Portion control.

  • Fewer calories are absorbed by the digestive system.

  • Long-term weight loss.

Benefits of SADI-S over Duodenal Switch

  • Fewer digestive alterations.

  • Fewer associated risks.

  • Lower complication rate.

  • Fewer associated GI side effects.

  • Less complicated surgery
