About Sleeve Gastrectomy

Sleeve gastrectomy or gastric sleeve surgery is a type of weight-loss surgery where the size of your stomach is reduced by removing the lateral 2/3rds of the stomach (approx. 75-85%) with a stapling device, shaping the remaining stomach into a tube or ‘sleeve’ so that you can only eat small meals. The gastric band procedure takes one to two hours. The surgeon will usually be able to work laparoscopically, which means that you will only need small, keyhole incisions. You will need to have a general anaesthetic.

The average person will lose about 50-60% of their extra weight with gastric sleeve surgery. However, the surgery won’t do all of the hard work for you. Although having gastric sleeve surgery should make sticking to your diet a little easier, you will still need to follow your diet plan very carefully.

What are the alternatives?

Surgery should only be used for weight loss after you have tried losing weight by dieting and exercising. Your doctor might also recommend trying certain medicines before considering surgery. If you are sure about bariatric surgery, you have a few alternative procedures to consider. In addition to sleeve gastrectomy, it is possible to have a stomach band fitted or to undergo a gastric bypass operation.

How It Works?

Gastric sleeve surgery involves the removal of a large section of your stomach. Reducing the size of your stomach will restrict the amount you can eat. It will also reduce your appetite by decreasing the production of appetite stimulating hormones in your stomach.

The sleeve gastrectomy is usually performed as a laparoscopic procedure, through four or five keyhole incisions. The operation will take one to two hours and requires a general anaesthetic. A large part of your stomach will be removed. The remaining section will be shaped into a sleeve or tube about the size of a banana and sealed using staples. You will need to stay in hospital for two to three nights after the procedure and it will be two or three weeks before you are fully recovered.
