Sleeve Gastrectomy

Sleeve Gastrectomy

The restrictive surgery or the sleeve gastrectomy, also known as the stomach stapling procedure tends to physically limit the amount of food you can consume by reducing the size of the stomach or the amount it can expand.

What to Expect?

This surgery is generally done using the laparoscopy method. There are three steps involved in this type of bariatric surgery:

  • The surgeon makes two to three small cuts on your abdomen and inserts a tiny camera inside the stomach. Then using a video monitor, your surgeon will remove part of your stomach.

  • The remaining portions of your stomach are joined together using surgical staples. This creates a long vertical tube or banana-shaped stomach.

  • The surgery does not involve cutting or changing the sphincter muscles that allow food to enter or leave the stomach

The surgery may take only 60 to 90 minutes if your surgeon has done many of these procedures. When you eat after having this surgery, the small pouch will fill quickly. You will feel full after eating a very small amount of food.


Here are some of the risks that are associated with the vertical sleeve gastrectomy:

  • Gastritis (inflamed stomach lining), heartburn, or stomach ulcers

  • Injury to your stomach, intestines, or other organs during surgery

  • Leaking from the line where parts of the stomach have been stapled together

  • Poor nutrition, although much less than with gastric bypass surgery

  • Scarring inside your belly that could lead to a blockage in your bowel in the future

  • Vomiting from eating more than your stomach pouch can hold

Before the Procedure

Your surgeon may ask you to have tests and visits with your other health care providers before you have this surgery. Some of these are:

  • A complete physical exam

  • Blood tests, ultrasound of your gallbladder, and other tests to make sure you are healthy enough to have surgery

  • Visits with your doctor to make sure other medical problems you may have, such as diabetes, high blood pressure, and heart or lung problems, are under control

  • Nutritional counselling

  • Classes to help you learn what happens during the surgery, what you should expect afterward, and what risks or problems may occur afterward

  • You may want to visit with a counsellor to make sure you are emotionally ready for this surgery. You must be able to make major changes in your lifestyle after surgery.

On the day of your surgery:

  • Do not eat or drink anything after midnight the night before your surgery.

  • Take the drugs your doctor told you to take with a small sip of water.

  • Your doctor or nurse will tell you when to arrive at the hospital.

After the Procedure

  • You can probably go home 2 days after your surgery. You should be able to drink clear liquids on the day after surgery, and then a puréed diet by the time you go home.

  • When you go home, you will probably be given pain pills or liquids and a medication called proton pump inhibitors.

Your doctor may recommend a diet for you. Meals should be small to avoid stretching the remaining stomach.
