Colon and Rectal Tumors, Colon Resection
Colon cancer is more commonly called colorectal cancer because the disorder most often affects both parts of the digestive tract, the colon and the rectum. It is one of the most common cancers found in the United States. The cause is unknown. In some people, the tendency to develop colon cancer may be inherited. Cancer is a disease in which the growth of abnormal cells, a tumor, leads to the destruction of healthy cells. If the tumor becomes invasive or aggressive, it may spread into the intestinal wall and to other sites, at which time the tumor is considered malignant.
Most malignant colon cancers and/or rectal cancers begin as apparently unthreatening (benign) growths (polyps) inside the colon or rectum. A colorectal polyp is a growth that projects (usually on a stalk) from the lining of the colon or rectum. Such polyps may become malignant although this is not always the case.
The symptoms of colorectal cancer may include changes in bowel habits, blood in the stools, constipation and/or diarrhea, abdominal discomfort and sometimes nausea. Surgery is generally performed to correct this type of cancer. It may be accompanied by radiation therapy and/or chemotherapy.
Surgery can be defined according to the indication: Inflammatory Bowel Diseases including Crohn’s disease and Ulcerative Colitis; Diverticulitis; Colonic Polyps and Colorectal Cancer. In colon cancer surgery, the cancer is usually removed, in a procedure often referred to as a colonic resection.
Another way of categorizing surgery is according to the anatomical location of the resection e.g. right hemi-colectomy, left hemi-colectomy, sigmoidectomy, anterior resection including low and very low, segmental resection and total colectomy.
Yet another way of categorizing surgery is according to the surgical technique used. There are two main techniques used in colon surgery: Open Surgery and Laparoscopic Surgery. NiTi’s ColonRing may be used in both types of Open or Laparoscopic procedures.
In a surgical procedure where a part of the colon is removed, there is a need to rejoin the remaining parts. The rejoining of the two parts is called anastomosis. Anastomosis is defined as the surgical joining of two ducts, vessels or bowel segments. “Anastomosis” originates from the Greek. The term anastomosis has been in medical use since the second century AD, when the Greek physician Galen used the term to describe the interconnections between blood vessels. The plural of anastomosis is anastomoses.
NiTi’s ColonRing is used for compression anastomosis in colorectal surgery. The technology used in the ColonRing is called BioDynamix™ Anastomosis and it encourages natural healing.
