Colectomy is a surgical procedure to remove all or part of your colon. Your colon, also called your large intestine, is a long tubelike organ at the end of your digestive tract. Colectomy may be necessary to treat or prevent diseases and conditions that affect your colon.
There are various types of colectomy operations:
Total colectomy - involves removing the entire colon.
Partial colectomy - involves removing part of the colon and may also be called subtotal colectomy.
Hemicolectomy - involves removing the right or left portion of the colon.
Proctocolectomy - involves removing both the colon and rectum.
