Gastric Sleeve Surgery

RESEARCH THE SLEEVE GASTRECTOMY PROCEDURE

How Does The Sleeve Gastrectomy Work?

The vertical sleeve gastrectomy is a restrictive form of weight loss surgery in which approximately 85% of the stomach is removed leaving a cylindrical or sleeve shaped stomach with a capacity ranging from about 60 to 150 cc, depending upon the surgeon performing the procedure. Unlike many other forms of bariatric surgery, the outlet valve and the nerves to the stomach remain intact and, while the stomach is drastically reduced in size, its function is preserved. Again, unlike other forms of surgery such as the Roux en Y gastric bypass, the sleeve gastrectomy is not reversible.

Because the new stomach continues to function normally there are far fewer restrictions on the foods which patients can consume after surgery, albeit that the quantity of food eaten will be considerably reduced. This is seen by many patients as being one of the great advantages of the sleeve gastrectomy, as is the fact that the removal of the majority of the stomach also results in the virtual elimination of hormones produced within the stomach which stimulate hunger.

Perhaps the greatest advantage of the gastric sleeve lies in the fact that it does not involve any bypass of the intestinal tract and patients do not therefore suffer the complications of intestinal bypass such as intestinal obstruction, anemia, osteoporosis, vitamin deficiency and protein deficiency. It also makes it a suitable form of surgery for patients who are already suffering from anemia, Crohn's disease and a variety of other conditions that would place them at high risk for surgery involving intestinal bypass.

Facts about the sleeve gastrectomy:

Alternative names: vertical sleeve gastrectomy, sleeve gastrectomy, greater curvature gastrectomy, parietal gastrectomy, gastric reduction and vertical gastroplasty.

Surgery for high BMI patients. For patients with a particularly high body mass index (typically 50+) many forms of weight loss surgery are either difficult to perform or present increased risk. As a result, a vertical sleeve gastrectomy (or increasingly a laparoscopic sleeve gastrectomy) is sometimes performed as the first of a two-part weight loss solution to provide an initial drop in weight which then makes other bariatric follow up possible at a reduced level of risk.

Surgery for low BMI patients. For obese patients with a relatively low body mass index the vertical sleeve gastrectomy can also prove a good choice, especially where existing conditions (such as anemia or Crohn's disease) prevent them from having other forms of bariatric surgery. In addition, patients may choose this form of surgery if they are concerned about the long-term effects of bypass surgery or object to having a 'foreign' body implanted into their body, as is the case with lap band surgery.

Laparoscopic Sleeve Gastrectomy Surgery

During sleeve gastrectomy, the surgeon will remove the larger, rounded part of the stomach.

• The remaining stomach looks like a sleeve (or hose or tube) and holds about 15 percent as much food as the original stomach.

• The surgeon will remove the larger, rounded part of the stomach from the body. (This is the only gastric surgery in which part of the  stomach is taken out of the body.)

• Unlike gastric bypass, which changes stomach openings, sleeve gastrectomy leaves the openings intact.

• It may be a safer and more effective option than gastric bypass for patients with very high BMI, those with medical problems like anemia, Crohn’s disease, osteoporosis, extensive prior surgeries and other complex medical conditions.
