Colorectal Cancer Surgery
Colorectal cancer affects about 140,000 people every year, making it the third most common cancer in both men and women. Colorectal cancer is most often treated with surgery to remove the tumor, and possibly, chemotherapy and radiation.
Colorectal Cancer Surgery Terms
Polypectomy is a procedure in which polyps -- small growths on the inner lining of the colon -- are removed during a colonoscopy, a procedure in which a special instrument (the colonoscope) is inserted into the rectum to view the rectum and colon.
Local excision can be used to treat cancers in the rectum (the lowest portion of the colon). The procedure involves removing the cancer and some tissue of the wall of the rectum. It may be done through the anus (the opening of the rectum) or through a small cut in the rectum. The procedure does not require major abdominal surgery.
Resection involves the removal of part, or all, of the colon along with the cancer and its attaching tissues.
Laparoscopic surgery The word "laparoscopy" means to look inside the abdominal cavity with a special camera or scope. To perform laparoscopy, between 3 and 6 small (5-10 mm) incisions are made in the abdomen. The laparoscope and special laparoscopic instruments are inserted through these small incisions. The surgeon is then guided by the laparoscope, which transmits a picture of the intestinal organs on a video monitor.
