Laparoscopic Sleeve Gastrectomy
The Sleeve Gastrectomy is now the most often performed weight loss surgery worldwide. During the procedure, the bariatric surgeon removes about 80% of the stomach, leaving a small, “sleeve-shaped” stomach.
The sleeve gastrectomy differs from the Roux-en-Y gastric bypass in that no alterations are made to the small intestine, so the gastrointestinal tract remains in continuity. Therefore, there is much less concern for malabsorption of food and vitamins compared with the bypass.
While the sleeve gastrectomy has not been performed as a stand-alone procedure for as long as the Roux-en-Y gastric bypass, it has been shown to produce similar outcomes including:
Improvement of type 2 diabetes
Lowered blood pressure
Lowered cholesterol levels
