Sleeve Gastrectomy

How Does It Work?

Sleeve Gastrectomy is a restrictive bariatric surgery. During this procedure, the surgeon creates a small, sleeve-shaped stomach. It is larger than the stomach pouch created during Roux-en-Y bypass—and is about the size of a banana.

What Are the Benefits?

Sleeve Gastrectomy is typically considered as a treatment option for bariatric surgery patients with a BMI of 60 or higher. It is often performed as the first procedure in a two-part treatment. The second part of the treatment can be gastric bypass.

Sleeve Gastrectomy is also an alternative for patients suffering from morbid obesity whose health risks are too complicated for traditional surgical weight loss methods.1

Important Statistics

  Typically patients lose between 33% and 83% of their excess weight 12 to 24 months after sleeve gastrectomy 2

  Resolution of obesity-related, co-morbid conditions (such as type 2 diabetes, hypertension, high cholesterol, and obstructive sleep apnea) occurred within 12 to 24 months after sleeve gastrectomy 2

  Sleeve gastrectomy patients experienced resolution rates for co-morbid conditions that were similar to resolution rates for other restrictive procedures such as gastric banding 2

  Resolved type 2 diabetes in 47% to 100% of patients in four studies 1,2,3,4

  Resolved hypertension in 15% to 93% of patients in four studies1,2,3,4

  Resolved high cholesterol in 45% to 73% of patients in two studies1,2,3,4

  Resolved obstructive sleep apnea in 56% to 100% of patients in three studies1,2,3,4

What Are the Risks, Complications, and Side Effects?

Additional risks and complications associated with Sleeve Gastrectomy include:

Dehiscence (separation of tissue that was stitched or stapled together)

  Leaks from staple lines
  Ulcers
  Dyspepsia
  Esophageal dysmotility
  Fistula
