|Minimal Invasive Laparoscopic Colon Cancer Surgery
- The surgeon enters the abdomen by placing a canula (a narrow tube like instrument) into the abdomen (belly) through a small incision (½ — ¼ inch)
- Carbon Dioxide gas is pumped into the abdomen through the port (cannula) to puff-up or inflate the belly, making working room for the surgeon.
- A laparoscope (a tiny telescope connected to a video camera) is placed through the canula, and allows the surgeon to see a magnified lighted view of the internal organs on a TV monitor
- 2 to 4 other canulas are inserted to allow use of special instruments to work inside the abdominal cavity (belly).
- If a portion of the colon is removed, one of the small canula incisions is slightly enlarged to permit removal of the tissue.
