What is gastric sleeve surgery (sleeve gastrectomy)?

Gastric sleeve or sleeve gastrectomy surgery is a type of weight loss surgery. It may be appropriate for you if you have a body mass index (BMI) of 35 or more. It is a more significant operation than having a gastric band fitted, however it is not considered as major as a gastric bypass since it involves fewer changes to your body’s digestive system.

Sleeve gastrectomy can be performed on its own, however it is sometimes performed as the first part of a two stage procedure. For patients considered too high risk for gastric bypass for example, the gastric bypass can be performed sometime after the gastric sleeve surgery once the patient has lost some weight.

About the gastric sleeve operation

The gastric sleeve procedure involves reducing the size of your stomach. During the operation up to ¾ of the stomach is removed by dividing it, with the new stomach taking the shape of a narrow tube or sleeve. This effectively restricts the stomach capacity without affecting its function, so that the amount of food that can be eaten at one time is restricted.

Gastric sleeve surgery can be performed either as “keyhole” surgery or through an incision in your abdomen during an open operation, and usually takes one to two hours. It is performed under general anaesthetic, which means you will be asleep during the procedure. You will normally need to stay in hospital for one to three days so we can look after you and make sure we are happy with everything before you go home.

How does the gastric sleeve differ from other weight loss operations?

Gastric sleeve surgery reduces the size of your stomach, unlike to the gastric bypass procedure which also affects the way food is absorbed. Compared to a bypass operation there are also fewer restrictions on the types of food that can be eaten following the surgery. Following gastric sleeve surgery patients often experience a reduction in appetite as the area of the stomach that has been removed plays a role in the amount of the hunger hormone your stomach releases and you may initially lose weight more rapidly than with a gastric band.

The gastric sleeve operation also differs from the gastric band procedure since it is a permanent reduction in the size of your stomach, and is not reversible.

After gastric sleeve surgery

Spire Thames Valley Hospital offers you fixed price packages so you can choose, with advice from the surgeon, the length of aftercare required. 

Once the sleeve gastrectomy has been performed, you will be provided with regular follow-ups by the specialist team to ensure you get the advice and support you need. They will help you make the changes to your diet and lifestyle that are necessary for you to achieve your weight loss goals. 

How much can I expect to lose?

Sustained long term weight loss success is related directly to a patient’s motivation and their commitment to following the dietary guidelines provided. However, a patient can expect to lose 50-60% of their excess weight within the first 18 months after the gastric sleeve has been performed.
If a patient had the same commitment to life-style changes using all 3 surgical procedures then the weight loss with a sleeve would tend to be greater than having a band but less than having a bypass.
