A colectomy is a surgical procedure that involves the removal of a part or the entire colon. When a patient presents with conditions such as a blocked colon, uncontrolled bleeding, or colorectal cancer, the doctor may recommend colectomy. Partial colectomy or bowel resection is the more common procedure undertaken in most cases. In such a procedure, a portion of the large intestine is removed and the remaining is restructured. In a few cases, the patient may need the removal of both the colon and the rectum. These surgeries are referred to as protocolectomy. Traditionally colectomy is done through a long incision in the belly but the introduction of laparoscopic surgeries has made the procedure minimally invasion with four small cuts that are quick to heal. Colectomy surgery is used to treat diseases such as Crohn’s Disease, Ulcerative colitis, Diverticulitis, and colon cancer.
