By Mayo Clinic staffColectomy is used to treat and prevent diseases and conditions that affect the colon, such as:
- Bowel obstruction. A blocked colon is an emergency that may require total or partial colectomy, depending on the situation.
- Bowel perforation. A torn colon is also an emergency that may require colectomy.
- Colon cancer. Early-stage cancers may require only a small section of the colon to be removed during colectomy. Cancers at a later stage may require more of the colon to be removed.
- Crohn's disease. If medications aren't helping you, removing the affected part of your colon may offer temporary relief from signs and symptoms.
- Ulcerative colitis. Your doctor may recommend total colectomy if medications aren't helping to control your signs and symptoms.
- Preventive surgery. If you have a very high risk of colon cancer due to the formation of multiple precancerous colon polyps, you may choose to undergo total colectomy to prevent cancer in the future. Colectomy may be an option for people with inherited genetic conditions that increase colon cancer risk, such as familial adenomatous polyposis or Lynch syndrome.
Discuss your treatment options with your doctor. In some situations, you may have a choice between various types of colectomy operations. Your doctor can discuss the benefits and risks of each.
