The Gastric Bypass Procedure Essay

938 words - 4 pages

The Gastric Bypass Procedure Gastric bypass, so named because it reroutes part of the small
intestine around much of the stomach, is done through a long incision
down the abdomen or sometimes through a small puncture with a scope.
The upper stomach is closed off with staples, reducing the functioning
stomach from the size of a football to a shot glass. The small
intestine is cut from below the original stomach and reconnected to
the upper pouch.

Pounds melt off for most patients because the new, tiny stomach fills
with just a few bites, and because food travels a shorter digestive
route - skipping the lower stomach and upper small intestine - so less

adjustable silicone band or bypassing most of the small intestine. But

patients dies from the surgery. Dr. E. Patchen Dellinger, chief of
general surgery at the University of Washington Medical Center, says
he surveyed Washington surgeons and found the risk to be about double
that, or one in 100.

Either way, the rate is significantly higher than that for most

Restrictive Operations

Restrictive operations serve only to restrict food intake and do not
interfere with the normal digestive process. To perform the surgery,
doctors create a small pouch at the top of the stomach where food
enters from the esophagus. Initially, the pouch holds about 1 ounce of
food and later expands to 2-3 ounces. The lower outlet of the pouch
usually has a diameter of only about ¾ inch. This small outlet delays
the emptying of food from the pouch and causes a feeling of fullness.

As a result of this surgery, most...
