Sleeve Gastrectomy


Also known as a “gastric sleeve” or “vertical sleeve gastrectomy”, the sleeve gastrectomy is a surgical procedure in which a majority of the stomach is removed to restrict food intake. While originally developed as a way to help obese patients lose weight prior to future surgery, the sleeve gastrectomy has been shown to have a number of powerful weight-loss and metabolic benefits independent of other procedures. This, coupled with advances in laparoscopic surgical techniques to minimize surgical risks, has made the gastric sleeve one of the most popular forms of metabolic surgery available today.

Dr. Wiljon Beltre, Board Certified lead surgeon at The Center for Metabolic and Obesity Surgery in Altamonte Springs, Florida, was one of the first surgeons to perform the gastric sleeve in Central Florida, and remains the only surgeon offering this procedure in Seminole Country. He is committed to staying abreast of cutting-edge surgical procedures and dedicated to helping his patients make educated, informed decisions about their weight loss and healthcare options, and his holistic, comprehensive approach to the entire weight loss journey ensures that you will receive the finest possible care and the warmest possible support as you pursue your weight loss and health-related goals.


The sleeve gastrectomy, as with other metabolic surgeries such as the gastric bypass, provides two different, but complementary, benefits. First, the sleeve gastrectomy causes significant and rapid weight loss by depressing the appetite and limiting the amount of food the patient can eat. By removing the portion of the stomach known as the fundus, the body’s ability to produce the appetite-controlling hormone ghelin is diminished, drastically reducing the amount the patient wants to eat. And because the post-operative stomach is smaller, the patient is able to eat less.

Second, sleeve gastrectomy has been shown to be extremely effective in the treatment of obesity-related health problems that, despite being linked to obesity, often fail to respond to weight loss. While the exact mechanism by which the gastric sleeve ameliorates high-risk health conditions is not known precisely, it is believed that the suppression of the gut hormones peptide tyrosine-tyrosine (PPY) and incretins, in addition to ghelin, has an immediate ameliorative impact on metabolic health problems such as hypertension, hyperlipidemia, gastro-esophageal reflux disease, and especially type 2 diabetes.


Most sleeve gastrectomies require a procedure time of approximately 1-2 hours in an hospital under general anesthesia. During the procedure, your surgeon will make 5-6 small incisions in the abdomen and insert trochars (pen-shaped tubes) into the body, enabling the surgeon to safely utilize a video camera and surgical instruments without making large-scale incisions, a surgical technique that greatly reduces recovery times as well as the risk of discomfort, scarring, and post-operative complications. The surgeon then removes about 70% of the stomach, leaving a vertical, banana-shaped “sleeve” of stomach between the esophagus and small intestine. The remaining stomach sleeve can hold between 50 and 150ml of food, about 10% of what the original stomach could hold. The gastric sleeve does not change the way the stomach processes food or bypass part of the intestine.

Because most sleeve gastrectomies can now be performed more safely with the use of laparoscopic surgical equipment, the risk of serious complications and side effects is much less than in past decades and this procedure is now considered as safe as most surgical procedures. However, all surgical procedures do entail a certain level of risk, and it is important that you review and understand all the risks inherent in sleeve gastrectomy surgery before proceeding.
