The purpose of Gastric Bypass, Roux en-Y is to help
me to achieve control of my weight, by reducing my capacity
for food, and by, decreasing my desire for food.
My stomach will be greatly reduced im size, and food
will pass directly into the second portion of the small
intestine, bypassing the lower stomach and the first
part of the intestine, which is called the duodenum.
This will cause me to feel full after only a few small
bites of food, I will also note an increased sense of
satisfaction after only a small meal. These changes
will assist me in my goal of improving weight management
The operation consists of..
and division of the stomach: My stomach
will be divided into two separate parts. The
upper part of the stomach, into which food will
pass, will be 15-30 cubic centimetres (one half
to one fluid ounce) in size. The lower stomach
will be bypassed, and will no longer contact my
Bowel Connection: My bowel will be
cut, about 15 Cm below the duodenum, and will be
re-arranged in a 'Y' configuration, to provide a
pathway for the food out of the stomach. It
will be connected to the upper stomach pouch by
a small opening, one half inch in diameter.
of the Gallbladder: If my Gallbladder is
abnormal in any way, it will be removed, to prevent
my having future problems and need for additional
Surgery: My abdomen will be examined
and "explored" at the time of surgery.
No other procedures will be performed, unless an
unexpected condition is found, which might affect
my immediate health or safety, and which indicates
necessary surgery to correct it.
Any surgical procedure requires the acceptance
of some risk, in order to gain the benefits sought from
the operation. The complications of this surgery
include the risk of anaesthesia, which is greater in
the morbidly obese. In addition, heart disease,
diabetes, high blood pressure and prior abdominal surgery,
especially prior surgery on the stomach, increase the
risk of surgery.
Problems likely to occur at and around the time of surgery
include bleeding, infection, leakage of bowel closures,
or bowel obstruction. The necessity to open the
stomach and bowel may lead to abscess formation in the
abdomen or formation of an abdominal communication of
the bowel with the skin. Injury to the spleen
may occur, requiring its removal. Pneumonia or
lung collapse can occur, or embolism of blood clots,
and can require assistance with breathing. Post-operative
depression or emotional imbalance is possible.
Other conditions may possible occur with less frequency.
Not all side effects or hazards of the operation may
be known, and the results of surgery cannot be guaranteed.
The operative mortality of similar procedures has been
0.5% in several thousand cases performed in many locations.
Every effort is made to prevent problems, and I understand
and accept that they may still occur.
There are several problems, which might occur from months
to years after the operation. Bowel obstruction
from adhesions or hernia formation is possible at any
time, as with any abdominal surgery. Gastric hyperacidity
and ulcers of the stomach or narrowing of the stomach
outlet may occur occasionally. Persistent nausea
is usually related to a poor eating pattern. Nutritional
deficiencies are possible, and use of high-potency multivitamin
and mineral supplements may be necessary for life.
Most patients who undergo Gastric Bypass, Roux en-Y
have lost significant amounts of weight, but there is
no guarantee of any weight loss from surgery.
The operation should be thought of as a tool to improve
control of weight, which require appropriate use, for
maximum benefit to occur. Weight loss usually
exceeds 50% of excess body weight, and many patients
lose 75-100% of excess weight. Health problems
associate with excess weight are also usually benefited.
Re-operation may be needed, at some future time, to
correct problems, which might occur. The Gastric
Bypass operation is reversible, although there is seldom
any practical reason to consider reversal.
