Sleeve gastrectomy

Sleeve gastrectomy is a bariatric surgical procedure involving resection of the greater curvature of the fundus and body of the stomach to leave approximately 15% of the original gastric volume (60 to 100 mL), thus creating a restrictive physiology. The postsurgical gastric pouch resembles a banana-shape 1.

It was originally proposed as the first part of a two-stage operation in obese patients with a BMI >60 kg/m2 or in high-risk patients. The weight loss in these patients was deemed successful and it began to be used as a standalone procedure 1.

  • upper GI series
    • long tubular gastric pouch with abrupt widening of the distal end of the pouch (secondary to preserved gastric antrum)
    • linear streak or outpouching of contrast may be seen within non-excised fundus which can mimic extraluminal leakage 1
  • CT examination
    • narrowed, tubular (banana-shaped) stomach which has a smaller calibre along its long axis, with abundant mesenteric fat at the expected location of the excised stomach
    • staple line identified along the greater curvature of the gastric pouch
  • leak
  • haematoma, haemorrhage, infection (early complications)
  • sleeve stricture (late complication)
  • gastric dilatation 4
  • gastro-oesophageal reflux 4
