Colectomy is the most common procedure performed to remove colon cancer cells. This is the surgical resection of all or part of the large intestine. It is also called large bowel resection. Colectomy is performed under general anesthesia by open surgery method or by laparoscopic method. The procedure takes about 1 to 4 hours.
This is a minimally invasive technique where several small incisions are made rather than one large incision. Three to five small incisions are made on the lower abdomen. A laparoscope, a telescopic video camera used to see the inside of the abdomen is inserted through an incision. Small surgical instruments are passed through the other 2 incisions and the colon is removed. Carbon dioxide (CO2) gas is filled in the lower abdomen and expanded for easier access and the diseased part of the colon is removed. The healthy ends are reattached and all the incisions are closed with sutures.
Complications of a colectomy procedure include infection at the operation site, bleeding, damage to nearby organs, and anastomotic leak.
Ways to lessen the risk of colon cancer include high fiber diets and vitamins, avoiding smoking and alcohol consumption, losing weight in the case of obesity and living a healthy life style. Colonoscopy is an excellent method to diagnose colon cancer early. Early diagnosis has led to improved outcomes in colon cancer.
