The sleeve gastrectomy is one of the newer bariatric surgery techniques available. You may also hear it referred to as a vertical gastrectomy or a restrictive vertical gastrectomy.
Using a laparoscopic or minimally invasive procedure, Dr Whittwell removes a large portion of the stomach and reshapes the remaining part into a long tube shaped like a slender banana. The new stomach tube does not stretch very much and can only hold between 1 and 5 ounces of food at a time. This helps you feel full after eating a very small amount of food and stay full for an extended time.
The part of the stomach that is removed normally produces a hormone that is responsible for making you feel hungry. Without it, your appetite usually decreases. The combination of smaller helpings, reduced appetite and less frequent meals results in weight loss.
Why use the Sleeve Gastrectomy?
Sleeve gastrectomy is similar to gastric banding where weight loss occurs because it restricts the amount of food you can eat. Some people prefer it because they do not want the gastric band inside them or they prefer not to have the periodic adjustments necessary with a band.
Weight loss with Sleeve Gastrectomy
Weight loss results with a sleeve gastrectomy are usually similar to those seen with the gastric band and, in some cases, approach results seen with the gastric bypass procedure.
