About
the
Vertical
Sleeve
Gastrectomy
Procedure
The Vertical Gastrectomy procedure (also called vertical Sleeve Gastrectomy, Greater Curvature Gastrectomy, Parietal Gastrectomy, Gastric Reduction and even Vertical Gastroplasty) is performed by approximately 15 surgeons worldwide. It was originally conceived of by a doctor in England and has been further developed and utilized in the United States, Germany and Belgium. It generates weight loss by restricting the amount of food that can be eaten (removal of stomach or vertical gastrectomy) without any bypass of the intestines or malabsorption.
The stomach pouch is usually made smaller than the pouch that Duodenal Switch patients have. Critics of this procedure state that while early results look promising, the lack of an intestinal bypass may lead to weight regain.
They
base
their
criticism
on older
data
from
gastroplasty
procedures
done in
the
1970's
and
80's.
Basically,
it is an
improvement
over
prior
gastroplasty
procedures,
which
are
rarely
done due
to
problems
related
to the
placement
of
staples,
silastic
rings
and mesh
around
the
stomach
pouch.
In
addition
to
avoiding
foreign
bodies,
the
other
advantage
over the
older
procedures
is that
the
excess
stomach
volume
is
removed,
not left
in
place.
This
possibly
eliminates
most Ghrelin
hormone
production
and
helps to
reduce
the
sensation
of
hunger
that
people
have.
Currently
it is
approved
by some
insurance
companies,
but may
be
considered
investigational
by
others.
