Single Anastomosis Duodeno Ileo + Sleeve (SADIS) Weight Loss Surgery Procedure

If you’re struggling with weight loss, there’s a new bariatric surgery that you might want to consider. It’s called the Single Anastomosis Duodeno Ileo + Sleeve (SADIS), or also referred to as the Single Anastomosis Duodenal Switch, and it’s a surgical weight loss procedure that’s gaining popularity around the world.

The SADI-S is a powerful bariatric surgery that can be effective for individuals who have struggled with regaining weight after other bariatric weight loss procedures.

SADIS is a combination of two different bariatric surgeries: the duodenal switch surgery (DS) and the vertical sleeve gastrectomy (gastric sleeve). In this article, we’ll dive into what SADIS is, how it works, and its potential benefits.

Firstly, let’s start with the basics. The duodenal switch is a weight loss surgery that involves removing a portion of the stomach and rerouting the small intestine to decrease the absorption of calories and nutrients. This is a similar concept to the gastric bypass bariatric surgery but differs in that it “bypasses” a larger portion of the small intestines. 

The sleeve gastrectomy, on the other hand, is a procedure that removes a large portion of the stomach, resulting in a smaller stomach size and reduced capacity for food intake.

SADIS combines these two procedures to create a more effective weight loss solution.

The Single Anastomosis Duodenal Switch is performed laparoscopically, meaning it’s minimally invasive and involves making small incisions in the abdomen.

One of the benefits of SADIS is that it’s a one-stage procedure, unlike the traditional duodenal switch, which is a two-stage procedure. This means that patients only need to undergo one surgery, which can reduce the overall risk of complications and shorten the recovery time. Additionally, SADIS has been shown to be effective in helping patients achieve significant weight loss.

According to a study published in the journal Obesity Surgery, patients who underwent SADIS lost an average of 65% of their excess body weight within 12 months of surgery. Another study published in the journal Surgery for Obesity and Related Diseases found that SADIS resulted in greater weight loss and improvement in overall health compared to the sleeve gastrectomy alone.

SADIS has also been shown to have a positive impact on other health conditions, such as type 2 diabetes, high blood pressure, and sleep apnea. In a study published in the journal Diabetes Care, researchers found that SADIS led to significant improvements in blood sugar control in patients with type 2 diabetes.

While SADIS is a promising weight loss solution, it’s important to note that it’s not without risks. As with any surgery, there are potential complications, such as bleeding, infection, and intestinal obstruction. Additionally, SADIS can lead to malabsorption of nutrients, which can result in vitamin and mineral deficiencies. Patients who undergo SADIS will need to take vitamin and mineral supplements for the rest of their lives to prevent deficiencies.

Overall, SADIS is a promising weight loss solution for patients who are struggling with obesity and related health conditions. It’s a one-stage procedure that combines the benefits of the duodenal switch and the sleeve gastrectomy to create a more effective weight loss solution. While there are potential risks and complications associated with the procedure, the benefits, including significant weight loss and improvement in overall health, make it a viable option for many patients.

If you’re considering SADIS, it’s important to talk to your doctor and discuss your options. Your doctor can help you determine if SADIS is right for you and can provide guidance on how to prepare for the surgery and manage your recovery. With the right support and care, SADIS can be a life-changing procedure that helps you achieve your weight loss goals and improve your overall health and wellbeing.
