Sleeve Gastrectomy


During a sleeve gastrectomy (also called gastric sleeve, vertical gastrectomy, restrictive vertical gastroplasty, or vertical sleeve gastrectomy) we divide the stomach vertically with a line of staples and remove a large portion of it using minimally invasive (laparoscopic) surgery. The remaining stomach is a long tube shaped like a very slender banana. It can hold between 1 and 5 ounces.

The surgery helps you lose weight by restricting the amount of food (and, therefore, calories) that can be eaten at one time. The part of the stomach that is removed also secretes a hormone called ghrelin which is partly responsible for appetite and hunger. Due to the decreased amount of ghrelin, sleeve gastrectomy patients experience a loss or reduction in appetite.

Bariatric surgery is not for the casual dieter and there are several requirements that you will need to meet in order to be considered. Let us guide you through this process in a simple fashion. First, we need to know your height and weight. This will allow us to Calculate your Body Mass Index. BMI is an indicator used globally to indicate a healthy weight. Learn more about Body Mass Index

Sleeve Gastrectomy Options

Dr Ayoola is proficient in minimally invasive techniques and we are happy to offer our patients different approaches to performing the sleeve gastrectomy.

  • Robotic Sleeve 
    • With this approach, patients will have fewer incisions and therefore less scaring
    • With this approach, patients experience less pain and a faster recovery
  • Single Incision Sleeve 
    • This involves performing the procedure through a small incision hidden in the belly button
    • There are no visible scars after the procedure
    • Dr Ayoola is the first to bring this technique to North Texas
  • Laparoscopic Sleeve 
    • This is the standard approach to sleeve gastrectomy
    • It is minimally invasive with a quick recovery
    • Dr. Ayoola performs this with fewer and smaller incisions than the traditional approach resulting in less scarring and quicker recovery

Gastric Sleeve Details

  • The gastric sleeve / sleeve gastrectomy is most similar to the lap-band procedure in that it is a purely restrictive procedure that causes weight loss by reducing your stomach’s capacity to hold food. Unlike the lap band, however, the gastric sleeve does not require periodic adjustments. There is no band wrapped around the stomach that can slip or erode surrounding tissue.
  • The tube portion of the stomach that remains after the surgery is more resistant to stretching because it is formed from a very muscular portion of the stomach. This makes it less likely that chronic overeating will increase your stomach’s capacity over time. However, if gastric sleeve patients consume a lot of soft, high calorie foods like ice cream, milkshakes, and creamy cheeses, it is possible for them to defeat the benefits of the procedure and slow their weight loss. Unlike the LapBand procedure, the gastric sleeve is not reversible as part of the stomach is completely removed from the body.
  • The Roux-en-Y procedure helps people lose weight through a combination of reduced stomach capacity and intestinal bypass that leads to nutrient malabsorbption. The gastric sleeve does not include an intestinal bypass, so it avoids the issues of nutrient deficiencies, marginal ulcers, and intestinal obstructions that may occur in intestinal bypass. The sleeve gastrectomy causes much less dumping syndrome than does the Roux-en-Y because the pylorus (the sphincter valve that controls flow of food out of the stomach into the intestine) remains intact.
  • Follow up information collected on sleeve gastrectomy patients at two and six years after surgery shows that the amount of weight people lose and keep off following a gastric sleeve is better than that seen with LAP-BAND surgery and in some cases approaches results reported with Roux-en-y gastric bypass.
