What Is Single Anastomosis Sleeve Ileal Bypass?

The Single Anastomosis Sleeve Ileal bypass, also called SASI bypass or just SASI, is a surgery performed laparoscopically on obese individuals to help them lose weight. SASI allows patients to realize the benefits of both gastric sleeve and gastric bypass weight loss surgery without the risk of severe malabsorption. It can be described as taking the best of both surgeries and combining them. SASI surgery can be done as a stand-alone procedure or can be used to modify an existing gastric sleeve surgery.

How Does SASI Bypass Work?

During the surgery, the stomach is reduced to about 75% of its original size. The surgery is performed with the use of a laparoscope where the lower part of the stomach is connected to the lower part of the small intestine and the beginning and middle sections of the small intestine are skipped. This is all completed without having to detach the stomach.

The alteration to the stomach and the intestines after SASI bypass allows the patient to eat only a small portion of food during one sitting and also inhibits the amount of sugar and fat the body can absorb which results in significant weight loss.

Why Consider Anastomosis Sleeve Ileal Bypass?

SASI combines the benefits of gastric sleeve surgery and gastric bypass surgery with fewer associated risks:

  • Patients can experience significant weight loss and reduction of weight-related health issues;
  • The impact on type 2 diabetes and reduction of high cholesterol is greater than with gastric sleeve surgery;
  • There is less of a risk to develop nutritional deficiencies because the duodenum is left intact which is where many of the nutrients are absorbed into the body.

According to the study published in 2019 where 20 obese patients with type 2 diabetes had SASI surgery and all were followed for a year, 75% of the patients experienced complete remission of their type 2 diabetes by the end of the third month following the surgery and 95% after a year.

How Much Weight Can I Lose with SASI?

The weight loss potential with SASI is very significant. This is a fairly recent addition to the bariatric surgery options. However, the results of the study published in 2016 showed an Excess Weight Loss (EWL) of 75% by the 6th month after surgery and EWL of 90% at 12 months. These weight loss results are significantly better than those historically obtained by other weight loss surgeries.

Who Is a Candidate For SASI?

You may be a candidate for single anastomosis sleeve ileal bypass if:

  • Your BMI is higher than 40+ or above 30 and you suffer from an associated weight-related disease, such as diabetes, sleep apnea, or high blood pressure;
  • You have made significant attempts to lose weight using diet, exercise, etc.;
  • You require a revision for a bariatric surgery that failed or did not provide the desired results;
  • You are in overall good health other than obesity-related issues;
  • You are not taking psychiatric medications or have illegal drug dependency problems;
  • You understand expected results and associated commitment;
  • You are not pregnant or planning a pregnancy in the very near future.

Are There Any Risks Associated with SASI?

As with any surgery, there are risks involved. Risks associated with single anastomosis sleeve ileal bypass can include:

  • Risks associated with the use of general anesthesia during surgery;
  • Leaking or bleeding along the staple line;
  • Ulcer formation at join, especially in smokers;
  • Acid/Bile Reflux.

When Will I Start Seeing Results?

Many patients begin to see results right away. The most significant weight loss normally occurs during the first three months. This will depend a large portion upon how well the patient follows the post-operative diet and exercise program.

Many patients also experience obesity-related health issues and diseases begin to be alleviated and possibly in remission between 3 and 12 months after surgery.

How Long Will The Results Last?

The results of bariatric surgery can be long-lasting if the patient is committed and determined to follow the after-surgery diet and exercise program. It also takes a commitment to a completely new way of living, thinking, and eating.

It is important to maintain a close relationship with your bariatric surgeon and complete all follow-up appointments.
