SASI Operation

What is Single Anastomosis Sleeve Ileal Bypass (SASI)

In the SASI operation, a portion of the stomach is removed, as in a sleeve gastrectomy operation than making a connection between the stomach and the small intestine, and thus it combines the gastric sleeve operation with the mini-gastric bypass surgery.

The SASI operation is performed laparoscopically and through small incisions in the abdominal wall.

The stomach is cut and the connection between the stomach and the intestine is made using modern staplers.  A leak test is performed at the end of the operation. In the SASI operation, part of the stomach is removed, which leads to a significant decrease in the amount of food consumed after the operation.

The level of the hunger hormone (Ghrelin) in the blood decreases after the SASI operation, as the part responsible for secreting most of the hormone is removed from the stomach.

In the SASI operation, food is diverted by connecting the new stomach to the small intestine. Thus, part of the food goes to the natural food pathway and the other part goes directly into the intestine via the bypass connection. you can do it with  The best gastric sleeve doctor


What happens after the SASI operation?

You can return to normal life and work after 5 to 7 days.
You can start walking from 30 to 60 minutes a day after you are discharged from the hospital.
Patients can start swimming after two months of the operation.

Does the SASI operation treat health problems related to obesity?

Research has proven that the SASI operation leads to the cure or improvement of many health problems associated with obesity, such as:

  1. Type 2 diabetes: Most studies indicated that the rate of improvement of diabetes after the SASI operation reaches 90% of cases, especially in the first years after the onset of diabetes.
  2. High blood pressure disease
  3. Sleep Apnea
  4. Polycystic ovaries and poor fertility in women
  5. Poor fertility
  6. Fatty liver disease
  7. Depression and psychological problems



What are the conditions for conducting the SASI Operation?

  1. BMI greater than 40 kg/m2
  2. BMI from 35 to 39.9 40 kg/m2 with one of the health problems associated with obesity such as:
    High blood pressure

Type 2 diabetes

  • Sleep Apnea
  • Fatty liver disease
  • High blood lipids

What are the benefits of using Laparoscopy in SASI operation?

1- Pain relief after the operation

2 – Reducing the length of hospital stay
3 – No visible wounds
4 – Faster recovery and return to normal life and work than traditional open surgery


We also use the patient-controlled analgesia painkiller (PCA) device, which prevents pain and makes the patient’s recovery faster after the operation. PCA is a method of pain relief in which the patient controls the amount of pain medicine that is used. When pain relief is needed, the person can receive a preset dose of pain medicine by pressing a button on a computerized pump that is connected to a small tube.

How does the patient get prepared for the operation?

  1. Before surgery, you should provide your doctor with a list of all medications, vitamins, minerals, and herbal or nutritional supplements that you are taking. After surgery, you may have restrictions on eating, drinking, and the medications you can take. 
  2. If you take blood thinners such as Aspirin or Marivan, talk to your doctor before surgery. Since these medicines affect clotting and cause bleeding, you may need to change the routine or the dose of this medicine before the operation. 
  3. If you have diabetes, talk to your doctor for specific instructions on taking or adjusting your medication before and after surgery. 
  4. Smoking of all kinds must be stopped at least two weeks before the operation.
  5. If you have high blood pressure, your blood pressure must be completely controlled before the operation, by regularly taking your medications and measuring blood pressure daily a week before the operation.

How long does the recovery take after the SASI operation?

  • The operation takes about 60 minutes.
  • The patient is discharged from the hospital 24 hours after the operation.
  • All patients are encouraged to walk as early as 3-4 hours after the operation.
  • Most patients return to work and/or school one to four weeks after the operation.
  • Fatigue is common in the first two weeks due to the decrease in calorie intake in the liquid diet phase. However, the majority of patients do not feel hungry during this phase of the diet. 
  • The energy level improves rapidly after the introduction of the soft diet, which takes about two weeks after surgery. 
  • We sometimes allow patients to work from home 2-3 days a week after surgery.
  • You can start walking from 30 to 60 minutes a day after pain relief. Patients can exercise two months after the operation.
