This procedure generates weight loss soley through gastric restriction (reduced stomach volume). The stomach is restricted by dividing it vertically and removing more than 85% of it. This part of the procedure is not reversible. The stomach that remains is shaped like a banana and measures from 2-5 ounces (60-150cc) depending on the surgeon performing the procedure. The nerves to the stomach and the outlet valve (pylorus) remain intact with the idea of preserving the functions of the stomach while reducing the volume. By comparison, in a Roux-en-Y gastric bypass, the stomach is divided, not removed, and the pylorus is excluded. The Roux-en-Y gastric bypass stomach can be reconnected (reversed) if necessary. Note that there is no intestinal bypass with this procedure, only stomach reduction.
On average, patients who undergo Vertical Gastrectomy surgery experience a 60-80% loss of excess weight.

No reliable statistics exist yet for how many of these procedures have been done. The current scientific literature supports use of sleeve gastrectomy as a primary bariatric procedure. This means that the indications for the sleeve are the same as other covered procedures such as gastric bypass or adjustable gastric banding.
The National Institutes of Health (NIH) requires a body mass index (BMI) greater than 40. This is the equivalent of being about 100 pounds overweight for men and 80 pounds overweight for women. People with BMIs between 35 and 39 may also be candidates for weight loss surgery if they have obesity-related illnesses such as diabetes, high blood pressure or high cholesterol. A BMI takes height and weight into account to measure body fatness. A BMI of 30 or higher in adults is considered obese.
Before gastric sleeve resection or any bariatric surgery, you must quit smoking, as smoking increases the risk for infections, pneumonia, blood clots, slow healing and other life-threatening complications after surgery. Ideally, you should permanently quit smoking, but even if you don't you must quit for at least one month before and one month after bariatric surgery.
Some surgeons require patients to go on special diets in the week(s) before the procedure.
As with all surgical weight-loss programs, it is imperative that VG patients adhere to a strict postoperative diet. Patients must stick to a liquid-based diet for 2 weeks after surgery; 4-6 weeks after the operation, patients graduate to a 600-800 calorie/ day solid diet. Once goal weight is achieved, usually 1-2 years after surgery, most patients can consume about 1000-1200 calories per day.
After surgery has been seen that some obesity-associated diseases (comorbidities) improve or even heal. Hypertension is cured in 60-65% of cases and 90% improvement. Cure diabetes mellitus in 90% and improvement in almost 100%.
