Single Anastomosis Duodeno-Ileal Bypass (SADI)

Single Anastomosis Duodeno-Ileal Bypass (SADI)
SADI-S surgery is an innovative approach to bariatric weight-loss surgery. Overweight patients who struggle to lose weight can benefit from SADI-S, which stands for Single Anastomosis Duodeno-Ileal (or jejunal) bypass with sleeve gastrectomy. This surgery is minimally invasive and has fewer risks than traditional weight-loss surgery options. It attaches the upper section of the small intestine to the lower section, directly bypassing the middle section so that food absorption is reduced, helping with overall weight loss goals. The procedure also involves a sleeve gastrectomy to reduce the size of the stomach, which further aids digestion and proper nutritional intake without feeling overly full after eating. SADI-S surgery presents an effective way for overweight individuals to reach their long-term weight loss goals with minimal complications safely.

Benefits Of The SADI-S Procedure

The SADI-S procedure is a new technique combining two different bariatric surgeries to help reduce weight and related medical conditions. The benefits of this procedure include significant weight loss due to restriction of food intake and malabsorption, relief or elimination of diabetes, hypertension, sleep apnea, and other associated problems, as well as safety for patients who are considered at high risk for traditional bariatric surgeries. Additionally, the technique’s quicker recovery time, compared to conventional procedures, can reduce the time spent in the hospital and get patients back to their daily activities sooner. With this new combined surgical approach, many more people will have access to the life-changing benefits of weight loss surgery.

How Is The Surgery Performed, And Does It Hurt?

The surgical procedure for SADI-S is a highly specialized and complex operation that uses laparoscopic techniques to give patients with obesity who suffer from type 2 diabetes the best possible chance at long-term health. During the procedure, the surgeon creates a bypass loop of the ileum to the beginning of the jejunum and then reduces the stomach size with a gastric sleeve. The process involves making several tiny incisions to allow access to both organs and can take up to three hours or more to complete. The most common questions regarding this procedure are typically about pain. Fortunately, SADI-S is minimally invasive, so discomfort during surgery and recovery is usually minimal. Patients generally receive general anesthesia for their comfort during surgery, which helps make any pain afterward manageable without additional treatment.

Eligibility Criteria For SADI

​At Nova Bariatrics, we follow a strict assessment protocol to qualify candidates for this surgery.  We examine the condition and evaluate whether or not SADI (Single Anastomosis Duodenal-Ileal Bypass) is the best option for you. The procedure starts off with checking preoperative parameters that include medical history and consultations with our bariatric surgeons to determine your suitability and if the surgery will yield the required outcome. 

You are automatically eligible for this surgery if:

  • Your Body Mass Index (BMI) is 40 or more.
  • BMI is in the range of 35-39.9 kg/m2 with obesity-related comorbidities such as Type 2 diabetes or sleep apnea,
  • Or, you have a BMI of 40 kg/m2 or greater, regardless of any history of obesity-related conditions.
  • We only perform surgeries on those who are 18 years of age or older.

Other than that, you must be set on making a lifelong choice to adjust to a healthier way of life. This means modifying your diet and introducing physical activity to maintain your weight loss post-surgery.

Success Rate Of SADI

Your stomach size is reduced by 80% after this procedure, rerouting a part of the small intestine to the remaining stomach and bypassing about 75% of the digestive system. After we perform SADI surgery on you, expect to lose between 80-90% of your excess weight within the span of 1.5 years, with the most significant shed occurring in the first 3 months. With this procedure, you will not only get rid of excessive weight but also alleviate many obesity-related comorbidities.

Frequently Asked Questions

What is SADI-S surgery?

SADI-S (Single Anastomosis Duodeno-Ileal bypass with Sleeve gastrectomy) is an advanced bariatric procedure that combines a gastric sleeve with a single intestinal bypass. It offers powerful, durable weight loss with a simpler design than the traditional duodenal switch. Dr. Alibhai offers SADI-S to patients who need significant weight loss or revision from a prior sleeve.

Who is a candidate for SADI-S?

SADI-S is typically recommended for patients with a higher BMI, those who need substantial weight loss, or those revising from a previous gastric sleeve that did not achieve enough results. A consultation with Dr. Alibhai at Nova Bariatrics determines whether SADI-S fits your medical needs.

How is SADI-S different from a duodenal switch?

SADI-S uses a single intestinal connection (anastomosis), while the traditional duodenal switch uses two. The single connection makes SADI-S a technically simpler operation with a lower risk of certain complications, while still delivering strong weight loss and metabolic benefits.

How much weight can I lose with SADI-S?

SADI-S produces significant, durable weight loss comparable to the duodenal switch, with many patients losing the majority of their excess body weight. As with all bariatric procedures, results depend on following the post-operative diet, vitamin plan, and follow-up schedule.
