Vertical Sleeve Gastrectomy / Sleeve
Gastrectomy
Expected Weight loss 60-80% of excess
weight
Description of the Vertical Sleeve Gastrectomy
Most
common weight loss surgery performed in the U.S.
This is the most modern weight loss procedure
that induces weight loss by restricting food
intake, invented back in 1999 but modified and
refined by Dr. Feng in 2002 to an optimal smaller
size to become a well-established, most popular,
stand-alone procedure.
The Vertical Sleeve Gastrectomy (VSG) is also
commonly known as the Sleeve
Gastrectomy, Restrictive Vertical Gastroplasty, or
just Vertical Gastrectomy (VG). The Vertical
Sleeve Gastrectomy is essentially a newer, better
version of the vertical banded gastroplasty, a
procedure that has been abandoned by virtually all
weight loss surgeons, due to high failure rates
and complications. Dr. Feng surgically reduces
the stomach in size to a long narrow, tube like,
vertical pouch, between 1-4 ounces in size,
keeping the valves of the stomach at the entry and
exit of food into the stomach which helps maintain
normal function.
There is no intestinal bypass performed, avoiding
many of the problems associated with malabsorption
of nutrients. In the past, the procedure was
usually reserved for high risk patients or super
obese patients with the intention of performing
another surgery at a later date. If necessary, the
second procedure would be either a duodenal switch
or gastric bypass.
Nowadays, no other surgeries are needed at all
anymore since patients loose as much as a gastric
bypass patient would. In general, all qualified
obese patients are considered and recommended for
undergoing this procedure. Most patients can lose
60 to 80% of their excess body weight over 6-12
months with sleeve gastrectomy alone.
Advantages of Vertical Sleeve Gastrectomy
Procedure
- Usually done laparoscopically
(minimally invasive) with robotic-assistance in
patients.
- Allows patients of any weight,
including the super super obese and high risk
patients, to undergo surgery with small
incisions
- Rapid weight loss
- Patients do not experience
diarrhea or significant “Dumping Syndrome”
symptoms
- The portion of the stomach
producing hunger-stimulating hormones (Grehlin)
is removed
- The smaller stomach maintains
normal function with no rearrangement of the
intestines, reducing risks of protein and
vitamin deficiency and thus no significant
"Dumping Syndrome" symptoms
- Minimal patient effort to lose
and maintain weight loss
- Better weight loss than the
Adjustable Gastric Band procedures
- Safe in patients needing long
term aspirin, NSAID such as Motrin, Advil,
naprosyn, steroid use
Disadvantages of Vertical Sleeve Gastrectomy
Procedure
- Successful results depend on
willingness to adopt long-term lifestyle changes
- Weight loss may be slower than
more malabsorption procedure type like the
duodenal switch
Risks of Vertical Sleeve Gastrectomy Procedure
- Leakage
- Nausea/vomiting
- Acid reflux
- Weight regain
- Rarely, allows for second
surgery for more weight loss
- Gallstones
