Sleeve Gastrectomy


What is Sleeve Gastrectomy?


During laparoscopic sleeve gastrectomy, the stomach is stapled and divided vertically. This procedure requires specially designed surgical staplers, using the keyhole/laparoscopic method. By doing this, a portion of the stomach will be removed. The much smaller size stomach helps restrict the amount of food the stomach can hold and reduces appetite.

Who is it for?


The Sleeve Gastrectomy procedure is suitable for those:

Who are overweight with Body Mass Index (BMI) over 35
Who have tried diet and exercise and are not reaping the desired effects
With Type 2 Diabetes, Hypertension, and other medical conditions related to obesity

Common FAQs


A: The risk of major post-op complications after a sleeve gastrectomy is 5 to 10%, which is less than the risk of a gastric bypass procedure. This is mainly because the small intestine is not divided and reconnected. 

Some complications may include a leak from the sleeve resulting in an infection or abscess, deep venous thrombosis or pulmonary embolism, narrowing of the sleeve (stricture) requiring endoscopic dilation and bleeding.

A: For high-risk patients and patients with very high BMI’s, we discuss LSG as a first-stage procedure prior to gastric bypass. For example, patients who have a very high body mass index (BMI) or severe heart or lung disease may benefit from a shorter, lower-risk operation such as the sleeve gastrectomy as a first stage procedure.

The chance of nutrient deficiency is also less likely with the gastric sleeve surgery than with gastric bypass surgery because there is no malabsorption. Ultimately, the decision regarding which procedure to perform is based on each patient’s operative risk and their expectations and goals for surgical weight-loss.


A: No matter which type of weight loss surgery you perform, it is only a tool to help you lose weight and keep it off if used effectively. 

The Sleeve Gastrectomy results in a banana-shaped, or sleeve-like stomach. Similar to the Gastric Band, eating sweets and drinks/ liquid high in calories will cause weight to regain, or result in poor weight loss.
