Sleeve Gastrectomy

The Sleeve Gastrectomy (SG) is a laparoscopically performed “restrictive” procedure which does not involve any surgery on or re-routing of the intestine. It is also known as tube or vertical sleeve gastrectomy, and is different from the stomach stapling procedures used in the past.

SG removes about three quarters of the stomach, which results in a decreased appetite and early feeling of fullness with smaller amounts of food. Food passes as normal down the oesophagus, through the resized stomach and into the small intestine.
