Synopsis

The SASI bypass can be a stand-alone procedure or done as a revision after a sleeve gastrectomy to promote additional weight loss or treat gastric reflux.

SASI surgery is a bariatric procedure that combines two weight loss surgeries: sleeve gastrectomy and intestinal bypass. It involves removing a portion of the stomach to create a smaller, sleeve-shaped stomach and rerouting the digestive system to help patients lose weight.

SASI surgery is a bariatric procedure that combines two weight loss surgeries: sleeve gastrectomy and gastric bypass. It involves removing a portion of the stomach to create a smaller, sleeve-shaped stomach and rerouting the digestive system to help patients lose weight.

SASI Bypass Benefits

Benefits of SASI bypass: 

Reduced stomach volume and reroutes 80% of ingested food that triggers changes intestinal hormone secretion. These changes help reduce feelings of hunger, promote fullness, facilitating weight loss without the usual pangs of hunger or food-related stress associated with traditional diet patterns.

The decreased stomach volume results in a longer-lasting sense of fullness. Meal size will be decreased and must be consumed slowly. Although stomach capacity may slightly increase over several months, it never returns to its prior size. Eating too much or too quickly can lead to stomach discomfort.

Because a large amount of food bypasses the small intestine, not all of it undergoes digestion and absorption, especially fats. When food directly reaches the middle part of the small intestine, the feeling of fullness is intense, curbing appetite and influencing food choices.

SASI Bypass Procedure

The SASI surgery involves a two-step process.

Traditional Sleeve

Initially, a traditional sleeve operation is performed, which entails the removal of approximately 80% of the stomach lengthwise, leaving behind a banana-shaped tube with a capacity of around 100-150ml. The larger portion of the stomach is completely removed from the abdominal cavity.

Anastomosis

Then, a new connection, called an anastomosis, is created between the remaining gastric tube and the middle segment of the small intestine. This change enables food to follow two directions: the natural route through the pylorus and the duodenum, and a direct path through the newly created connection to the middle portion of the small intestine.

Research has indicated that approximately 80% of ingested food bypasses the small intestine and enters the lower small intestine directly following the surgery, while the remaining 20% follows the normal digestive route.

How is this different from other procedures?

Unlike conventional bypass procedures like roux-en-y, gastric bypass and mini bypass, which divert food entirely away from the duodenum and the initial part of the small intestine, the SASI surgery maintains stimulation of all segments of the intestines by ingested food. 

This intricate procedure has many benefits,

Including the reduction of vitamin and micronutrient deficiencies and the minimization of the risk of bacterial overgrowth in the bypassed section of the intestine.

Importantly, this surgery is performed using laparoscopic techniques, similar to other bariatric surgeries.

Typically, individuals with a BMI of 40 or higher, or those with a BMI of 35 or higher with significant obesity-related health issues, may be considered candidates for bariatric surgery.

Candidates often need to demonstrate that they have made previous attempts to lose weight through diet, exercise, and other non-surgical methods without long-term success.

SASI bypass can also be an option for those who have previously had a sleeve gastrectomy. 

If you have obesity-related health conditions such as type 2 diabetes, sleep apnea, high blood pressure, or heart disease, you may be considered a candidate for weight loss surgery.
Candidates should be willing to make significant lifestyle changes, including dietary modifications and regular exercise, both before and after surgery.
Many healthcare providers require candidates to undergo a psychological evaluation to assess their readiness for the emotional and behavioral changes that come with bariatric surgery.
Your age, overall health, and any medical conditions may also be considered when determining candidacy.
Candidates should have a clear understanding of the risks, benefits, and potential outcomes of the surgery and provide informed consent.
Ultimately, the decision to undergo any bariatric surgery should be made with the help of an experienced bariatric surgeon who can evaluate your individual circumstances, discuss your goals, and assess whether the procedure is appropriate for you. They will consider your medical history, current health status, and other factors to make an informed recommendation.

FAQ

FAQ .

How Does Surgery Work?
In this procedure, the surgeon first performs a sleeve gastrectomy by removing a significant portion of the stomach, reducing its size. Then, they reroute the small intestine to connect to the smaller stomach pouch, bypassing a portion of the small intestine. This reduces the amount of food that can be eaten and absorbed, leading to weight loss.
Is the SASI Reversible?
The surgical alterations to the stomach and digestive system are intended to be permanent. Reversing the procedure is typically complex and not commonly done.
What Are the Benefits of SASI Surgery?
The SASI can lead to significant and sustained weight loss, which can improve or resolve obesity-related health conditions such as diabetes, sleep apnea, and high blood pressure.
What Are the Risks and Complications?
Like all surgical procedures, the SASI carries risks, including infection, bleeding, and adverse reactions to anesthesia. Specific complications can include dumping syndrome, nutritional deficiencies, and gastrointestinal issues.
How Long Is the Recovery Period?
Recovery time varies, but most patients can expect to spend a few days in the hospital after surgery. Full recovery and adjustment to new dietary habits typically take several weeks to months.
Will I Need to Follow a Special Diet After Surgery?
Yes, you will need to follow a specific diet plan after surgery. Initially, you'll consume a liquid or pureed diet before gradually transitioning to solid foods. You'll also need to take vitamins and supplements to prevent nutritional deficiencies.
What Lifestyle Changes Are Required After Surgery?
Commitment to a healthier lifestyle is crucial for long-term success. You'll need to make permanent changes to your diet, exercise regularly, and attend follow-up appointments with your healthcare team.
Will My Insurance Cover SASI Bypass Surgery?
Coverage varies by insurance plan and location. Some insurance providers cover bariatric surgery if specific criteria are met. It's essential to contact your insurance company and verify your coverage.
