Sleeve Gastrectomy

A sleeve gastrectomy is a medical procedure that involves surgically removing part of the stomach.

What happens?

During sleeve gastrectomy, the surgeon will make a cut into your abdomen before removing the left side of your stomach. This can reduce your stomach’s volume by up to 75%. This operation is usually performed using keyhole surgery.

The remaining part of your stomach is pulled upwards and resealed using stitches. This creates a much smaller and longer stomach that looks like a sleeve

During a gastrectomy, the surgeon connects the oesophagus either to the small intestine or the remaining section of stomach. This means you will still have a working digestive system.

The operation takes about an hour to perform and you will usually stay in hospital for two nights. Most individuals return to work 2-3 weeks later.

What are the risks?

Possible complications of a gastrectomy for obesity include:

• Nausea and vomiting, which usually get better over time
• Internal bleeding, which can lead to blood clots forming
• Leaking from where the stomach has been closed
• Acid reflux, where stomach acid leaks back up into the oesophagus infection

It may be possible to treat some complications with medication, but others may need further surgery.

Before your operation, ask your surgeon to explain the possible risks and how likely they are to affect you.
