A sleeve gastrectomy (also known as a gastric sleeve procedure) is a restrictive procedure to remove about 70% to 85% of your stomach so that it takes the shape of a tube or sleeve.

A sleeve gastrectomy differs from other bariatric procedures as food enters the new stomach pouch/tube and then follows a normal route versus bypassing the digestive tract. As a result there are no absorption issues with a sleeve gastrectomy. The aim of sleeve gastrectomy is that you feel full sooner and therefore eat less. 

What happens during and after a sleeve gastrectomy?

  • This operation is performed laparoscopically under general anaesthetic and usually takes between 2-4 hours
  • Your surgeon will make several small incisions (cuts) in your abdomen (stomach)
  • They then insert a viewing tube with a small camera (laparoscope) and other tiny instruments into these small incisions to remove part of your stomach
  • The tube-shaped stomach that is left is sealed closed with staples
  • It is important to note: unlike some other procedures, sleeve gastrectomy is not reversible
  • You will be taken to a recovery area following your operation
  • Our healthcare team will monitor your blood pressure and heart rate
  • You will be given pain relief medication
  • You may have small drains (tubes) in your wounds to drain away any excess fluid
  • You may also have a catheter that drains urine from your bladder
  • These will all be removed before your go home
  • Once you are on a ward you will be encouraged to get up and move about slowly
  • You will be on a liquid only diet for the remainder of your hospital stay
  • Your stomach may feel bruised and sore
  • Be sure and let us know if you are in any discomfort
  • Your stay in hospital will depend on your own situation
  • Discuss your discharge plan with your consultant.

Going home after sleeve gastrectomy surgery

  • You will not be able to drive so please arrange for someone to take you home on your day of discharge
  • It is important that you follow all the dietary recommendations we give you
  • You will need to remain on a liquid diet for several weeks progressing to soft, moist foods
  • It may be 4-6 weeks before you can begin to add solid food
  • Once you are eating solid foods it will be important to maintain a healthy diet to aid in continued weight loss
  • Be sure and contact a member of our healthcare team if you have any questions
  • Most patients return to normal activities within 2-4 weeks following sleeve gastrectomy
  • Be sure and discuss any return to work and exercise with your consultant.

As with any procedure there may be complications including:

  • Pain
  • Bleeding
  • Infection
  • Scarring
  • Blood clots (deep vein thrombosis – DVT)
  • Developing a hernia in the scar

Specific complications of sleeve gastrectomy may include:

  • Damage to internal organs
  • Staple line bleeding
  • Staple line leak or perforation of the stomach or bowel
  • Nutritional deficiencies.
