A colorectal resection is a surgery to remove a section of the large intestine, also called the colon. It is done to remove injured or diseased parts of the colon.

This surgery is performed to treat a variety of conditions, including the following:

  • Colorectal cancer
  • Diverticular disease—small pouches form in the wall of the colon
  • Inflammatory intestinal diseases, such as colitis, Crohns disease
  • Intestinal blockage
  • Trauma to the intestine
  • Precancerous polyps, especially those seen in familial polyposis
  • A hole in the wall of the colon, or a dead piece of intestine
  • 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.
