Gastric
Bypass
Surgery
Cost,
Roux
en-Y
(Proximal)
is
the
most
commonly
employed
gastric
bypass
surgery
technique,
and
is
by
far
the
most
commonly
performed
bariatric
procedure
in
the
United
States.
It
is
the
operation
which
is
least
likely
to
result
in
nutritional
difficulties.
The
small
bowel
is
divided
about
45
cm
(18
in)
below
the
lower
stomach
outlet,
and
is
re-arranged
into
a
Y-configuration,
via
a
"Roux
limb".
The
Roux
limb
is
constructed
with
a
length
of
80
to
150
cm
(30
to
60
inches),
preserving
most
of
the
small
bowel
for
absorption
of
nutrients.
The
patient
experiences
very
rapid
onset
of
a
sense
of
Gastric
Bypass
Surgery
stomach-fullness,
followed
by
a
feeling
of
growing
satiety.
Roux-en-Y
Laparoscopic
Procedure
The
surgeon
makes
5-6
small
incisions,
then
inserts
special
instruments
through
the
openings.
These
instruments
permit
the
insertion
of
the
laparoscope
camera.
The
abdomen
is
then
filled
with
gas
to
help
the
surgeon
view
the
abdominal
cavity
via
the
camera
and
video
monitor.
Stomach
Pouch
and
Bypass
During
the
roux-en-Y
operation,
the
stomach
is
divided
and
separated
using
staples.
Finally,
the
bottom
of
the
Gastric
Bypass
Surgery
stomach
is
connected
to
the
base
of
Gastric
Bypass
Surgery
the
new
roux
digestive
tract
or
'limb',
permitting
juices
from
the
stomach
and
pancreas
to
mingle
with
the
food
and
enhancing
nutrient
absorption.

invasive
approach
is

clinical
experience
in
the
U.S.
•
