Laparoscopic Sleeve Gastrectomy

Thu, 06/10/2010 - 6:21am

Is a new procedure that induces weight loss by restricting food intake. With this procedure, the surgeon removes approximately 85 percent of the stomach laparoscopically so that the stomach takes the shape of a tube or "sleeve." It is larger than the stomach pouch created during Roux-en-Y bypass—and is about the size of a banana.

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.

Expected Weight Loss:
Most patients can expect to lose 30 to 80% of their excess body weight over a 6 - 12 month period with the sleeve gastrectomy alone.
