Colorectal Surgery Q & A


What is colorectal surgery?

Colorectal surgery involves surgery of the colon (large bowel) and rectum. Colorectal surgery may be needed for the following conditions:

  • Diverticulitis
  • Ulcerative colitis
  • Crohn's disease
  • Cancer of the colon and rectum
  • Traumatic injury
  • Obstruction
  • Ischemia
  • Fistulas

By repairing or removing the damaged section of the colon, normal function can be restored.

Dr. Kalan specializes in performing colorectal cancer surgery.

What is colorectal cancer?

Colorectal cancer is one of the leading causes of cancer deaths in the United States, despite the fact that it’s preventable and, if caught early on, highly treatable.

Colorectal cancers most often develop from polyps. These are growths in the tissues lining your colon and rectum. Although generally harmless, sometimes these polyps undergo cellular mutations and turn cancerous. Without treatment, the tumors can grow and eventually spread into other parts of your body.

Routine colonoscopy is the best way to detect polyps and early stages of colorectal cancer. If you have any polyps, removing them during the colonoscopy prevents them from becoming cancerous.

What types of colorectal surgery are there?

Colorectal surgery often removes a section of bowel. Dr. Kalan then reconnects the two healthy ends together. This procedure can usually be done using minimally invasive techniques.

If you have rectal cancer, you might need operations such as a low anterior resection, a very low anterior resection, total mesorectal excision (TME), or an abdominoperineal resection depending on the location of the tumor in the rectum. 

Colorectal surgery is very complex and requires specialized training. The specific procedure that is performed on each individual patient is determined by the stage of the disease, the patient’s health status, history of prior surgery, and other technical factors.
