Gastric Sleeve Surgery

Most patients who undergo the gastric sleeve operation lose 50-75% of their excess body weight over 12-24 months. This operation is advised if:

  • Your Body mass Index (BMI) is 30 or more
  • You have obesity related health conditions
  • Previous attempts at losing weight have failed
  • You are looking for safe, tested surgical solution

Sleeve gastrectomy (“gastric sleeve”) is a common weight loss operation. The outer part of the stomach is removed and the shape of the stomach is changed from a sac to a long narrow tube (sleeve). The gastric volume is reduced from approximately 2L to 100-150 mL.

The main effect of the gastric sleeve is thanks to the reduced volume of the stomach and hence only a small amount of food is need to create a feeling of ‘fullness’ and satiety. Using the gastric sleeve as a tool for portion control allows the committed patient to eat 3 small meals per day and feel satisfied, unlike being on a diet. The subsequent reduction in caloric intake will result in weight loss. Good food choices in addition to regular exercise are also necessary to optimise outcomes.

Recent studies have shown that the top fundus part of the stomach, which produces the hunger hormone Grehlinand is removed during the gastric sleeve sleeve operation, results in a loss of feeling hungry. Although, this effect does lessen with time for some patients.

Increasingly, the gastric sleeve has been performed as a stand alone procedure with acceptable results (eg: excess weight lost of 50 – 75%). The main surgical complications are bleeding and leakage from the cut edge of the remaining stomach (reported: 1-3 %).

A recent positional statement from ASMBS (American Society for Metabolic and Bariatric Surgery) has accepted the gastric sleeve as a stand-alone procedure with a risk/benefit profile between laparoscopic adjustable gastric banding and Roux-en-Y gastric bypass.
