This is a procedure to remove all or part of the colon. The colon, or large intestine, is the lower part of the intestines. In a partial colectomy, only part of the colon is removed. In a total colectomy, all of the colon is removed.

A colectomy may be done to treat a variety of conditions, including:

  • Colorectal cancer
  • Inflammatory intestinal diseases such as colitis and Crohn’s disease
  • Intestinal blockage
  • Trauma to the intestine
  • Diverticular disease —small pouches in the wall of the colon
  • Precancerous polyps, especially those seen in familial polyposis
  • A hole in the bowel wall, or a dead piece of bowel
  • Bleeding from the colon

For colon cancer, the goal is to remove all of the cancer. If you have a precancerous condition, then you may have prevented the development of cancer. If you had surgery due to other conditions, a successful operation will alleviate or improve your symptoms.
