Roux-en-Y Gastric
Bypass
Weight
loss has
been
shown to
occur
more
rapidly
and over
a longer
period
of time
with
gastric
bypass
as
opposed
to
stapled
gastroplasty
(see
below).
The
reasons
for
superior
weight
loss
stem
from the
small
degree
of
malabsorption
caused
by
bypassing
nearly
all of
the
stomach
and the
first
two feet
of the
small
intestine.
To date,
weight
loss
with
gastric
bypass
has been
much
more
consistent
than
with
stapled
gastroplasty.

Laparoscopic
(Minimally Invasive)
Gastric Bypass
Recently,
surgeons have
performed several
anti-obesity
operations including
gastric bypass using
minimally invasive
techniques. This
approach uses five
or six tiny
incisions instead of
one large incision
to perform the
operation. These
operations require
two skilled,
well-trained
surgeons, skilled
assistants and many
new specialized
instruments.
During the
procedure, a
laparoscope is
inserted into the
abdomen. This
provides the
surgeons with a
magnified view on a
TV monitor. The
result is better
visualization
throughout the
procedure, allowing
for more precise
work.
By eliminating the
large abdominal
incisions, bowel
manipulation and
extensive
dissection, patients
are assured a faster
recovery. Further
advantages of the
laparoscopic
approach include
less pain
following the
surgery,
less scarring,
and likely an
earlier discharge.
LAP-BAND®
(Adjustable Gastric
Band)
In adjustable
gastric banding (the
LAP-BAND®
System), the stomach
is encircled with an
inflatable band that
provides restriction
of food intake. This
allows only a small
portion of the
stomach to be used
for holding food. A
person feels full on
much less food.
Weight loss achieved
is less than with
gastric bypass since
no intestine is
bypassed and there
is no malabsorption.
This procedure is
superior to
gastroplasty, as it
is adjustable to
optimize weight
loss. Absence of
stapling during this
procedure makes it
the least invasive
and lowest risk.

Gastroplasty
The upper stomach
is stapled in a
vertical direction
with a pre-measured
plastic band
separating the upper
and lower stomach as
shown in Figure 4.
The band prevents
the stomach from
stretching at this
point.
We use specific
criteria pertaining
to an individual's
health and potential
risks when deciding
who should have a
gastroplasty and who
should have a
gastric bypass. Most
patients will
qualify for
laparoscopic gastric
bypass surgery.
Laparoscopic
Sleeve Gastrectomy
The sleeve
gastrectomy is a
more recently
introduced surgery
for weight loss. It
is rapidly gaining
popularity among
those seeking
permanent weight
loss. Only a handful
of laparoscopic
surgeons nationwide
perform this
surgery.
It involves the
removal of
approximately 75% of
the stomach, leaving
about a 2-3 ounce
stomach, now
structured as a
narrowed tube. The
normal continuity
between the
esophagus, stomach,
and small intestine
is not changed, as
it is in gastric
bypass. Therefore,
food is normally
absorbed and there
is no risk of
vitamin or mineral
malabsorption. The
small size of the
new stomach limits
caloric intake and
decreases some of
the hormones that
stimulate appetite.
Therefore, patients
feel less hungry,
which greatly helps
with weight loss.
Sleeve Gastrectomy
is a safe and
effective option for
patients with 100
pounds or more to
lose. On average,
sleeve gastrectomy
patients lose about
60-65% of their
excess body weight
within 18 months.
