What is the definition or description of: colon and rectal surgery?

Colorectal Surgery: Colon and rectal surgery does not have a particular definition. In fact, it is a medical specialty that deals with problems in the colon, rectum, and anus. A sampling of diseases that fall in this realm are colon cancer, rectal cancer, inflammatory bowel disease (such as ulcerative colitis or crohn's), rectal prolapse, hemorrhoids, anal fistulas, and more). Not all of these require surgery.
