What is SADIS Surgery?

SADIS surgery, which stands for “Single Anastomosis Duodeno-Ileal Switch,” is an innovative technique in bariatric surgery.

This revolutionary procedure uses internal anchors to create a kind of “sleeve” around the stomach, helping to control food consumed and promote effective weight loss.

In simpler terms, imagine the stomach becoming a smaller and more controlled pouch that limits the amount of food you can consume, allowing you to feel full with less food.

This, combined with a healthy eating and lifestyle plan, can be a valuable tool for people struggling with overweight and obesity.

Advantages of SADIS Surgery

SADIS offers many advantages over other surgical weight loss treatments, including:

  • More weight loss than sleeve gastrectomy or Roux-en-Y gastric bypass.
  • Greater resolution of diabetes.
  • Potentially fewer ulcers, stenosis, and obstruction of the small intestine.
  • Less blood sugar fluctuations than gastric bypass.
  • Fewer complications than the duodenal switch.
  • Better weight loss outcomes: Compared to gastric bypass and sleeve gastrectomy surgery, SADIS helps you lose more weight. One study reported that patients lost an average of 40 percent of excess weight in the first year after surgery.
  • Lower risk of post-surgical complications: Lower risk of dumping syndrome and diarrhea compared to gastric bypass, lower risk of internal hernia (intestinal obstruction).
  • A second chance for patients who have undergone previous weight loss surgery: SADIS is a safe and effective option for patients who have already undergone bariatric procedures such as sleeve gastrectomy.
Are You a Candidate for SADIS Surgery?
  • The SADIS procedure is primarily recommended when Sleeve Gastrectomy has failed or there has been weight regain during follow-up, in patients with Type 2 Diabetes Mellitus, or if your Body Mass Index (BMI) is greater than 40.
  • However, the SADIS procedure is not suitable for you if you suffer from severe esophageal reflux and Barrett’s esophagus; in this case, Gastric Bypass might be your best option.
  1. Small incisions are made in the abdomen to access the stomach and small.
    intestine. (laparoscopy)
  2. A portion of the stomach is removed, creating a smaller stomach pouch.
  3. The small intestine is rearranged, and a single anastomosis (connection) is
    made between the duodenum and the ileum.
  4. This configuration reduces the length of the intestine involved in nutrient absorption.

The surgery typically takes around 2 to 3 hours.

  • Patients usually stay in the hospital for 1 or 2 days for monitoring.
  • Gradual progression from a liquid diet to solid foods.
  • Follow-up appointments to monitor progress and provide ongoing support.
  • Your surgery includes nutritional and psychological follow-up for a full year after your surgery.

After bariatric surgery, patients must make significant changes in their lifestyle and diet. These changes include:

  • Eating smaller portions.
  • Adopting a balanced and protein-rich diet.
  • Exercising regularly.
  • Following medical and nutritional follow-up recommendations.

It is important to remember that Bariatric Surgery is an effective tool for weight loss, but long-term success depends on the patient’s commitment to a healthy lifestyle.

Consulting with an experienced bariatric surgeon like Dr. Cristobal Garza is essential to understand the procedure and its implications.

Consider this before undergoing Bariatric Surgery:
  • Your must commit to a lifestyle change.
  • The need for long-term medical and nutritional follow-up.
  • The importance of following medical recommendations.
  • This is an irreversible surgery.
  • The patient must be aware of the importance of supplementing with vitamins and B12 for the rest of their life.

Although SADIS surgery is generally safe, there are risks and possible complications, including infection, bleeding, suture leaks, intestinal obstruction, and long-term nutritional issues.

When considering surgery like this, be sure the professional team you choose has the surgical equipment, experience, facilities, and staff to handle any complication if needed.
