Laparoscopic Adjustable Gastric Banding
An adjustable band is placed around the top part of the stomach
to create a small pouch. The size of the band is adjusted using a port
placed under the skin. Adjusting the band changes how quickly food
leaves the new pouch.
Staples are used to create a vertical tube of the stomach. Food
passes in limited amounts through the tube and creates fullness and
Roux-en-Y Gastric Bypass
A large portion of the stomach is closed off. This leaves a
small pouch to hold food, restricting the amount that can be eaten
at one time. The small intestine is cut below the duodenum and
reattached to the new stomach pouch, leaving a shortened path for food
to travel through.
