The incision --

The procedure involves an incision, typically running between the tip

of the breast bone and the navel. (Although the length of the incision

can vary depending on the size of the individual, how they carry their

weight, etc. Also, a person of up to about 400 lbs can still have it

done laparascopically, depending on the surgeon.)

The stomach is divided into two parts --

The stomach is completely separated into two parts using a cutting

surgical stapler and over-sewing. The upper part forms a small

(approx. 30 cc or 1 ounce) pouch which will receive food.

The small intestine is carefully measured and cut --

The larger, lower (distal) part of the stomach is bypassed, as is the

first approximately 150 cm of the small intestine (jejunum). This part

of the stomach receives most of the gastric juices coming from the

liver and other organs. The small intestine is cut at this point.

The small intestine is connected to the small pouch --

The lower part of the small intestine is brought up and is connected

to the small stomach pouch. Food will pass through a small (12 mm,

about the size of an M&M) opening (stoma) from the small pouch into

the small intestine.

Bypassed part of the small intestine is reconnected, forming " Y " --

The end of the 150 cm bypassed section of small intestine coming from

the large stomach pouch is reconnected approximately 200 cm from where

it was attached to the small pouch, forming a " Y " . Care is taken to

ensure that at least 200 cm of small intestine is available between

this junction and the large intestine to insure good absorption of

essential nutrients.

The Surgery helps you lose weight in three ways

1. You eat less (Volume restriction)

With a separate small stomach pouch, you feel full after eating a

small amount of food. This approach is much more effective in

restricting food volume than other surgical techniques, such as

stomach stapling.

2. Your appetite changes (Behaviour modification)

The procedure reinforces a change in your eating habits. After the

procedure, most patients find that their body will not easily tolerate

foods that are high in refined sugars and fats. With this built-in

control, called " the dumping syndrome, " which produces short-term

discomfort and flu-like symptoms, you naturally learn to avoid these

foods. Other surgical procedures don't provide this important benefit

of behaviour modification.

3. You absorb fewer calories (Malabsorption)

Food bypasses part of the small intestine and digestion occurs in the

lower part of the small intestine. These two factors reduce the amount

of calories your body absorbs from the food you eat.

What are the risks? --

Bariatric surgery is performed to enable patients to lose excess

weight and reduce the serious weight-related health conditions they

experience. Every surgery involves risk and bariatric surgery is

considered a major abdominal surgery. Patients need to understand

these risks and weigh them against the significant risks related to

being seriously overweight. Surgeons need to review these risks in

detail in their consultations with patients.

Hope this answers your question,
