Colon Resection, or colectomy, is surgery to remove part or all of the large intestine. This surgery may be necessary due to a variety of problems, including: colon cancer, a blockage in the colon, an inflammatory bowel disease like Crohn’s disease, an accident that caused colon damage, or polyps (non-cancerous growths in the colon).
During a colon resection, the surgeon removes the diseased part of the colon, or the entire colon if necessary, and then reconnects the digestive tract. The procedure can take up to four hours.
