During colon surgery, the section of the colon that is affected is cut out, and the two ends of the colon are reattached. The goal here is to re-create a functioning colon. In some cases, when the colon or rectum can’t function normally, a new opening to the outside of the body (called a stoma) is created. The intestine is connected through the opening to an external bag where waste is collected – this is called a colostomy. In some cases this colostomy can be reversed. Colon resection surgery has usually been performed using traditional “open” procedures, which require large incisions. With the advancement of technology and the development of new techniques, there are now minimally invasive options (with small incisions) that are just as effective. Minimally invasive colon surgery usually reduces the pain and scarring from the procedure and may speed the recovery process.
