Before beginning your radiation therapy, you will be taken to the operating room for the laparoscopy procedure. The laparoscopy procedure involves placing a telescope-like instrument through a small, usually ½ inch, incision (cut) in the abdomen. Three other small incisions are made to place additional instruments that may be needed to complete the surgery. Before the laparoscope is inserted, carbon dioxide gas (CO2) is introduced into the side of the abdomen. This gas helps to separate the organs inside the abdominal cavity, making it easier for the surgeon to see. The laparoscope is then inserted through the small incision. The laparoscope has a small camera on the end of the instrument. This is attached to a high-resolution TV monitor. Using the TV monitor, the surgeon can see inside your body without making a large incision. While watching the TV monitor, the surgeon uses the laparoscope to find the para aortic lymph nodes and removes them. Once the procedure is finished, the carbon dioxide gas is removed and you are taken to the recovery room.
