We work with expert teams of surgeons who are specially trained in surgical removal of benign (non-cancerous) and malignant (cancerous) tumors of the colon. There are different procedures used for colorectal surgery and your surgeon will recommend the most appropriate one for you depending on your tumor size and its location.
Polypectomy
Small cancers that are in their early stage and contained in the polyp can be removed during a colonoscopy – where a flexible tube with a camera is passed through the rectum. A polypectomy is commonly performed with a wire loop that is passed through the colonoscope and used to cut the polyp with an electrical current.
Local excision
Your surgeon can also remove larger polyps during a colonoscopy. In this instance, surgical equipment is passed through the colonoscope and is used to remove the polyp and a small part of the healthy colon lining that surrounds the cancer. This procedure is also called an endoscopic mucosal resection.
Partial colectomy
For more advanced cancers that have spread throughout the colon, your surgeon may recommend a partial colectomy. In this procedure, you’ll have the portion of colon that contains the cancer removed, along with some healthy parts of the colon either side. Your surgeon may also reconnect the ends of the colon and rectum after surgery.
Low anterior resection
This procedure is similar to a partial colectomy but for cancers that are in the rectum. During a low anterior resection operation, the cancerous part of your rectum will be removed, along with some nearby tissue and lymph nodes. The end of your colon is then reattached to the remaining part of your rectum. Your surgeon may recommend this if your colorectal cancer is large but far enough from the anus so that waste can leave your body normally.
Total colectomy
In some cases, your surgeon may have to remove all of the colon, this is called a total colectomy. This isn’t commonly used to treat colorectal cancers, but it may be necessary if you have an additional condition in another part of your colon, such as familial adenomatous polyposis or inflammatory bowel disease.
Colostomy
In colorectal cancers that are blocking your colon or rectum, or are located near your anus, you may require surgery to create a new way for your waste to leave the body. Your surgeon will cut out a portion of your colon or rectum and attach the end to a stoma – an opening in the skin of the abdomen. This can help you recover enough to start other treatments, such as chemotherapy. The type of colostomy you’ll have will depend on which part of your colon or rectum is cut out. In some cases, this is only temporary, and your colon and rectum can be surgically put back together in a separate procedure.
