Prior to the procedure:
Before the procedure:
General anesthesia will be given through an IV (needle) in your hand or arm. It will block pain and keep you asleep through surgery.
Description of the Procedure
A nurse will place an IV line in your arm to give you fluid and medicines. A breathing tube will be placed through your mouth and into your throat. This will help you breathe during surgery. You will also have a catheter placed in your bladder to drain urine.
Your doctor will make several small cuts in your abdomen. Gas will be pumped in to inflate your abdomen, making it easier for the doctor to see. A laparoscope and surgical tools will be inserted through the incisions. A laparoscope is a thin, lighted tool with a tiny camera. It sends images of your abdominal cavity to a monitor. Your doctor will operate while viewing the monitor.
The doctor will use surgical staples to divide the stomach vertically. The new stomach will be the shape of a slim banana. The rest of the stomach will be removed. Your new stomach can hold 50-150 mL (milliliters) of food, about 10% of what a normal adult stomach can hold. Incisions will be closed with staples or stitches.
In some cases, the doctor may need to switch to open surgery.
Immediately After Procedure
The breathing tube and catheter will be removed.
