Leading up to your procedure:
General anesthesia will be used. You will be asleep for the surgery.
To prepare you for surgery, an IV will be placed. You may receive fluids and medications through the IV during the procedure. A breathing tube will be placed through your mouth and into your windpipe. This will help you breathe during surgery. You will also have a catheter placed in your bladder to drain urine.
Several small incisions will be made in the abdomen. Gas will be pumped in to inflate the abdomen. This will make 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 the abdominal cavity to a monitor in the operating room. Your doctor will operate while viewing the area on this monitor.
An adjustable round band is placed around the top of the stomach and fastened into place. This creates a smaller stomach area for food. Tubing is placed from the band to an access port in the abdominal wall. The band can later be adjusted with a special saline solution and needle syringe. The incisions will be closed with staples or stitches.
The breathing tube will be removed. You will be taken to the recovery area while the anesthesia wears off.
Anesthesia will prevent pain during surgery. Pain and discomfort after the procedure can be managed with medications.
