Gastric Sleeve Surgery

Gastric sleeve surgery, also known as a sleeve gastrectomy, is a type of weight loss surgery that involves removing a large portion of the stomach to create a smaller, sleeve-shaped stomach.

By reducing the size of the stomach, gastric sleeve surgery helps you feel full after eating smaller portions. The procedure can also affect hormones involved in hunger and appetite, which may help support weight loss and changes in eating habits.

Procedure Gastric Sleeve

Gastric sleeve surgery is performed using minimally invasive laparoscopic surgery and does not involve rerouting the digestive system. The procedure is designed to support significant and sustained weight loss when combined with long-term changes to nutrition, physical activity and lifestyle.

EXPECTED WEIGHT LOSS: 25% total body weight loss

What happens during a gastric sleeve procedure?

​​Gastric sleeve surgery is usually performed using laparoscopic (keyhole) surgery under general anaesthetic. During the procedure, the surgeon removes a large portion of the stomach, leaving a smaller, sleeve-shaped stomach. The remaining stomach is approximately the shape and size of a banana. About 70% to 80% of the stomach will be removed during the procedure.

The smaller stomach limits the amount of food that can be eaten at one time and can help you feel full sooner. The procedure also reduces the amount of the hunger hormone ghrelin produced by the stomach, which may help reduce feelings of hunger.

 

ADVANTAGES OF GASTRIC SLEEVE SURGERY:

  • Laparoscopic procedure “keyhole surgery” so less invasive
  • Simply reduces the amount of food consumed
  • Normal stomach emptying
  • Less malabsorption
  • A further operation (bypass) can be added later if insufficient weight loss

DISADVANTAGES OF GASTRIC SLEEVE SURGERY:

  • Not reversible (but can be converted to a one anastomosis gastric bypass)
  • Possible long-term weight regain if tube stretches
  • Risk of bleeding or suture line leak immediately after operation
  • Can worsen reflux in some
  • Increased risk of Barrett’s oesophagus has been reported
  • Requires a lifelong multivitamin

RECOMMENDED FOR PATIENTS WITH:

  • A BMI of 40 or above
  • A BMI of 35 or above with obesity-related health conditions
  • A BMI below 35 with significant obesity-related health conditions
  • A history of progressive obesity and unsuccessful non-surgical weight loss
  • Previous attempts at weight loss through lifestyle changes and medication without lasting results

RECOVERY AND POST-SURGERY CARE:

After gastric sleeve surgery:

  • you will stay in hospital for 1 night
  • you will have pain relieving medications to keep you comfortable
  • you will be given instructions to follow regarding wound care, diet and activity
  • you will take Somac or Nexium for 4 weeks and then stop if reflux free

Patients should:

  • Keep the incision area clean and dry
  • Avoid strenuous exercises and lifting heavy weights for 2 weeks
  • Sip water throughout the day to prevent dehydration
  • Follow the diet recommendations given to you by the dietitian
  • Follow a weight loss exercise program to maintain weight loss

POSSIBLE COMPLICATIONS:

  • Possible failure due to poor dietary choices after surgery, or mechanical failure such as the dilation of the stomach tube
  • Bleeding or leakage from the stapled edge of the stomach
  • Scarring causing strictures
  • Nutrient deficiencies
  • Gastroesophageal Reflux
  • Gallstones
  • Modest weight regain if tube stretches
  • Wound infection
  • Venous Thromboembolism
