Sleeve Gastrectomy

Sleeve Gastrectomy

The sleeve gastrectomy, also known as the gastric sleeve resection, or tube gastrectomy, is an operation in which approximately 80–90% of the stomach is removed to reduce its capacity to around 100 to 200mL.

Normally, the stomach is a pouch which can take a large volume of food and fluid (up to 2 litres) and expand while doing so. This allows us to eat a meal which is much larger than required to maintain a healthy weight. Almost all weight loss procedures attempt to reduce the stomach’s capacity in some way. With a sleeve gastrectomy the large redundant part of the stomach is removed permanently.
