To prepare you for surgery, an IV will be placed in your arm. You will receive fluids and medications through this line during the procedure. 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 be used to create a small pouch at the top of your stomach. This pouch, which can hold about one cup of food, will be your new, smaller stomach. A normal stomach can hold 4-6 cups of food.
Next, the small intestine will be cut attached to the new pouch. With the intestinal bypass, food will now move from the new stomach pouch to the middle section of the small intestine. It will skip the lower stomach and the upper section of the small intestine.
Finally, the upper section of the small intestine will be attached to the middle section of the small intestine. This will allow fluid that the lower stomach makes to move down the upper section of the small intestine and into the middle section.
When the bypass is completed, the incisions will be closed with staples or stitches.
