Gastric Sleeve Surgery
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
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
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
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.
