will be given through an IV. It will block pain and keep you asleep through the surgery.
Description of the Procedure
An IV will be placed in your arm to give you fluids and medications. 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.
An 8-10 inch incision will be made to open the abdomen. Surgical staples will 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.
Staples or stitches will be used to close the incision.
Immediately After Procedure
The breathing tube and catheter will be removed.
How Long Will It Take?
About 2 hours
How Much Will It Hurt?
Anesthesia will prevent pain during surgery. Pain and discomfort after the procedure can be managed with medications.
Average Hospital Stay
The usual length of stay is 4-6 days. If there are any problems, you will need to stay longer.
