Roux-en-Y
gastric
bypass (RGB).
This
operation is
the most
common
gastric
bypass
procedure
performed in
the U.S.
First, a
small
stomach
pouch is
created by
stapling
part of the
stomach
together or
by vertical
banding.
This limits
how much
food you can
eat. Next, a
Y-shaped
section of
the small
intestine is
attached to
the pouch to
allow food
to bypass
the duodenum
as well as
the first
portion of
the jejunum.
This causes
reduced
calorie and
nutrient
absorption.
This
procedure
can now be
done with a
laparoscope
(a thin
telescope-like
instrument
for viewing
inside the
abdomen) in
some people.
This
involves
using small
incisions
and
generally
has a more
rapid
recovery
time.
Extensive
gastric
bypass
(biliopancreatic
diversion).
In this
more
complicated
gastric
bypass
operation,
the lower
portion of
the stomach
is removed.
The small
pouch that
remains is
connected
directly to
the final
segment of
the small
intestine,
thus
completely
bypassing
both the
duodenum and
jejunum.
Although
this
procedure
successfully
promotes
weight loss,
it is not as
widely used
because of
the high
risk for
nutritional
deficiencies.
Minimal Incision Roux en- Y Gastric Bypass
There are different approaches
to accomplish operations. These approaches have
been adapted for procedures in the abdomen as well
as other areas of the body, such as the chest.
They are:
1) Traditional open surgery
2) Minimally invasive surgery
a. Laparoscopic
b. Minimal incision
The Minimal incision approach
falls within the category of minimally invasive
surgery, as does Laparoscopic surgery. Both
approaches minimize the incision length and thus
reduce trauma and thus minimizes recovery time and
postoperative pain. In minimal incision bariatric
surgery, the same operation is accomplished as
with traditional open surgery, however the
incision size is greatly reduced, and are on the
order of about 4 inches or 10 cm. The total length
of the multiple small incisions used for
laparoscopy and the length of the single small
incision used for minimal incision surgery are
about the same, and therefore the amount of pain
and recovery time from both approaches are
comparable.
Typically patients that have
had their bariatric surgery thru the minimal
incision approach will leave the hospital on the
3rd hospital day (post-op day #2), which is as
good or better than those that have the operation
thru the laparoscopic approach.
