Vertical Sleeve Gastrectomy

Vertical Sleeve Gastrectomy, Denver

The Vertical Sleeve Gastrectomy procedure provides a weight-loss outcome that is midway between Roux-en-Y gastric bypass and the laparoscopic adjustable band (lap-band). This procedure was first performed on patients with a BMI more than 50, which is considered super-obese and the risk of performing gastric bypass was too high. In this first iteration, if desired weight-loss wasn't achieved, a second procedure could be performed to convert to bypass. More recently, however, this procedure has become used as a single procedure operation with minimal risk.

Advantages of the Vertical Sleeve Gastrectomy include:

  • desirable weight loss
  • co-morbidity resolution
  • relative ease of technique
  • avoidance of a foreign body or adjustments
  • immediate restriction of caloric intake.  

This procedure is, however, irreversible, though it can be converted to other weight-loss procedures. 

Brief Description of the Vertical Sleeve Gastrectomy

This surgical weight-loss procedure involves permanently removing a large portion of the stomach. The remaining portion is formed into a thin tube or "sleeve." Weight loss is achieved by restricting the amount of food the body can consume. Additionally, the part of the stomach that procedures Ghrelin (the appetite stimulator) is removed. 

After Vertical Sleeve Gastrectomy 

At one year after surgery, weight loss is estimated to be 70% of excess body weight. Weight loss is often dramatic at first and then continues at a slower, but steady rate. Patients who have type 2 diabetes as an obesity-related co-morbidity, 70% will have diabetes go in to remission (no longer requiring insulin or mediation). Those with sleep apnea or hypertension, 60% can expect obesity-related illnesses to go in to remission, allowing medications to be eliminated.

This procedure allows patients to lose a substantial amount of weight without nutritional deficiencies, as long as a healthy and balanced diet is maintained.
