What Is SADI-S Surgery? Single Anastomosis Duodeno-Ileal Bypass Explained

If you have been researching weight loss surgery procedures, you may have heard of a surgery called SADI-S and be curious about what it is. Short for Single Anastomosis Duodeno-Ileal Bypass with Sleeve Gastrectomy, this is one of the most effective bariatric surgeries currently available and is becoming an increasingly popular option. Dr Amjad Umair, a leading bariatric surgeon at Slimthetics, famous for this surgery. ‘It is a combination of a sleeve gastrectomy and an intestinal bypass and provides large and sustainable weight loss to the right candidates. Most people ask this question What Is SADI-S Surgery? Before undergoing this procedure.

Understanding SADI-S Surgery

SADI-S surgery consists of two major stages. First, the surgeon creates a sleeve gastrectomy, which is a tube of a narrow, stomach-sized banana. Next, a joining (anastomosis) is created between the duodenum and a section of the small bowel, bypassing part of the digestive tract. This decreases the stomach’s capacity to hold food and the calories and nutrients absorbed.

The SADI-S surgical procedure involves just a single anastomosis, or connection, between the intestines, which is a much simpler operation than traditional duodenal switch surgery where two intestinal connections are made. This makes the procedure easier, decreases surgical time, decreases the risk of some complications and provides excellent weight loss results.

How Effective Is SADI-S Surgery?

A common question that’s often asked is how much weight will be lost after an 18-month SADI-S surgery. Slimthetics clinical data and patient results demonstrate that at the 18-month mark, patients experience 70-80% excess weight loss from SADI-S surgery. Dr Amjad Umair points out that SADI-S surgery is especially effective for patients with a very high BMI and/or those who have not lost enough weight from other weight loss surgeries such as the gastric sleeve or gastric bypass.

Who Is a Good Candidate for SADI-S Surgery?

Not everyone is an ideal candidate for SADI-S surgery. Dr Amjad Umair usually suggests this process when patients:

  • BMI (body mass index) of 40 or above, or 35 or above if there is a health condition related to obesity.
  • Have tried and failed to achieve desired weight loss through less invasive weight-loss procedures.
  • Are willing to make long-term dietary and lifestyle modifications.
  • Have overall good health to undergo a more complex surgical procedure.

Slimthetics can evaluate SADI-S surgery in depth to ascertain whether it is the most secure and effective treatment for a specific patient.

Benefits of SADI-S Surgery

  1. SADI-S surgery has become increasingly popular among bariatric surgery patients for several reasons:
  2. More weight loss than just sleeve gastrectomy or gastric bypass.
  3. Shorter operative time than traditional duodenal switch surgery, thanks to the single anastomosis.
  4. Better control of obesity-related health problems such as type 2 diabetes, hypertension, and sleep apnea.
  5. Properly preserved pyloric valve function, which limits dumping syndrome, compared with gastric bypass.

What to Expect During Recovery?

Recovery after a SADI-S surgery is similar to other weight loss surgeries in that it also follows a recovery pattern:

  •  Stay in the hospital for 1-2 days after surgery.
  • 2–4 weeks before going back to regular routine.
  • A gradual introduction of food to the diet from liquids to purees to solid foods over a period of weeks.

Vitamin and mineral supplementation for the remainder of the individual’s life to prevent deficiency. Since nutrient absorption is a major part of SADI-S surgery, Slimthetics provides complete nutritional counseling and follow-up to ensure that patients don’t develop any deficiencies and remain healthy.

 Risks and Considerations

SADI-S surgery carries risks similar to any major surgery, including nutritional deficiencies, leakage at the anastomosis site, and the need for lifelong supplementation. That’s why it’s important to have an experienced surgical team. Dr Amjad Umair states that careful patient selection and post-operative monitoring at Slimthetics can minimise these risks and maximise their long-term outcomes.
