SASI bypass surgery is a bariatric procedure that combines a sleeve gastrectomy with a gastric bypass to further reinforce the effects of the weight loss procedure. This way, it combines the advantages of restrictive and malabsorptive operations to maintain the effects of weight loss for longer periods of time. Furthermore, it not only helps you maintain weight at a manageable level but also improves digestive health.
Unlike conventional procedures, the surgery will first target volume reduction of the stomach and then combine it with a strategic intestinal connection. The resulting digestive pathway limits nutrient and calorie absorption in the body, so only essentials are absorbed. It’s also important to note that traditional gastric bypass completely reroutes food away from the first part of the small intestine, where most vitamins and minerals are absorbed. This is why bypass patients need to rely on supplements to get their necessary nutrients. However, with the SASI bypass, you have two pathways for food, in which a partial food stream bypasses the small intestine while the remainder continues on the original path.
We perform the procedure at our state-of-the-art clinic in Medellin using advanced laparoscopic techniques. For this, the patient is administered general anesthesia. The procedure typically takes 3 hours to complete, after which the patient is kept at the hospital under observation for the next 48 hours. Want to learn more about the procedure?

SASI is a weight loss procedure designed to help individuals who are obese or suffering from obesity-related health concerns. It is also aimed at patients who have unsuccessfully attempted other weight loss methods. Here are some requirements that are typically evaluated to determine if you are an ideal patient for the procedure:
These are only general requirements. However, it is always best to consult a specialist to determine if this procedure is right for you.

If you have been approved as a candidate for the procedure, you will be assigned your surgery date. On the day of surgery, you will arrive at the clinic accompanied by a support person. Additionally, you will be recommended to observe an 8-hour fast before your procedure. You will be greeted by Dr. Adolfo Uribe and our specialized surgical team within the operating room.
Once the anesthesia has taken effect, Dr. Uribe and the surgical team will perform your surgery using a minimally invasive laparoscopic procedure. Five small incisions, each measuring 0.5 cm, will be surgically placed along the abdominal cavity. Prior to this, the surgical field will be inflated with medical-grade carbon dioxide gas to ensure sufficient space for the precise manipulation of the internal tissue and muscle.
Then, using the LigaSure vessel-sealing scalpel, the surgeon will cut through the tissue. This advanced equipment allows for minimal bleeding and promotes a safer procedure. The surgical team will mobilize the left portion of the stomach so it can be moved to the side. The first step is to cut down the stomach size. The exact dimensions of the new, reduced stomach are determined by inserting a guide tube through the esophagus into the stomach.
Next, the surgical stapler, a type of surgical scissors, is used to grasp the stomach and apply the predetermined division line along it. Following this, Dr. Uribe and his surgical assistant place sutures directly and precisely.
The next step of the surgery involves repositioning the small intestine. From the midpoint, the intestine is raised to the stomach and connected via a new exit. The result is two potential routes for the ingested food:
Before the procedure is finalized, a methylene blue leak test is performed to ensure all staple lines are tightened. Manual sutures may also be applied to the small intestine’s attachment to the stomach to avoid complications or internal hernias.
Please also note that patients who have gallstones or gastric reflux associated with a hiatal hernia can opt for a concurrent procedure as part of their SASI bypass surgery. Learn more by scheduling your consultation with us.

The results of your procedure can truly be actualized over the course of the following year. However, most patients achieve up to 60% to 70% of their original weight loss goals. It effectively reduces your stomach’s capacity for food intake and reconfigures the intestinal motions to sustain weight loss even further.
The SASI bypass procedure offers several benefits that distinguish it from traditional bariatric procedures:
