Transanal Resection

Transanal resection is a surgical procedure used to remove both rectal tumors and polyps. Rectal cancer is not uncommon to man. It is normally diagnosed through your anal colonoscopy or sigmoidoscopy. When polyps and tumors develop in the rectum, you do not notice them. It may take years before you notice any symptoms. Sometimes those symptoms include bleeding, soreness, or pus. By the time you notice symptoms, it may already be cancer. It is very important to stay up on your yearly physical so these things can be diagnosed early. If you do receive a cancer diagnosis, transanal resection is a method of treatment that can be helpful.

Rectal cancer is serious, and there are nearly 40,000 new cases yearly. It is the third most common cancer, and it does affect both men and women equally. A lot of times those with rectal cancer tend to have colon cancer as well. The rectum and colon are in such close proximity that the cancer cells can move into each area fairly quickly. Rectal cancer occurs as a result of abnormal cells growing in the rectum. These cells form tumors that can be all different sizes. Polyps are benign tumors, and they are usually smaller. The problem with polyps is that they can be precursors to cancer. Although polyps are not initially harmful, transanal resection is necessary for removing polyps, so they do not become harmful later.


Transanal resection is a procedure that removes tumors and polyps in the rectum. Transanal resection may also be called transanal excision. Transanal resection is typically used in beginning stage rectal cancer. The best treatment for beginning stage rectal cancer is tumor removal. After removal the tumor, the doctor will then try chemotherapy and radiation. There is a limit to the size of the tumor or polyp that can be removed with transanal resection. Larger tumors must be removed in other ways.

Transanal resection is a minimally invasive surgery. It requires the use of an endoscope. This is much better because incisions are small, so the risks of surgery are much lower. During the procedure, the doctor inserts an endoscope through the anus to remove the tumor or polyp. There is no need for an incision to the outside of the body. The endoscope, once inserted, cuts the wall of the rectum. The cancerous parts of the wall are completely removed. The physician will also cut away some of the good tissue surrounding the cancerous tissue. This is just a preventative measure, just in case cancer has spread. Polyps may also be removed with this procedure. This procedure cannot reach tumors that are too far into the colon. The tumors have to be close to the anus. During surgery, you are wide awake. The doctor only using local anesthesia to numb you.


Transanal resection is a great method of treatment for both rectal and anal polyps. The surgery has many benefits. Since you do not have any cuts on the outside of your body, your recovery is easier and quicker. The surgery is also fairly quick, and there is no need for sewing anything up at the end. This is good because the risk of infection is low and there is typically not a lot of bleeding. Another good thing about this procedure is that it can be done during your annual colonoscopy or sigmoidoscopy. If the doctor notices any tumors or polyps during this routine procedure, they will go ahead and remove them and send them for a biopsy. If the biopsy comes back showing cancer, you may not even need another surgery because the doctor removed all of the cancerous tissue.

Important Note

After a transanal resection, the rectum remains intact. It is good because there is no need for using a bag to use the bathroom. The doctor likes to talk to you about the procedure and how well it went. They will also discuss new things they saw and give you instructions for recovery. Because you only had local anesthesia, you will be okay to go about your daily activities. When the numbness wears off, you will be sore so you should probably keep your activities light. It is not mandatory that you have a driver, but if you want company, that is fine.

Transanal resection is a great method of treatment for polyps and rectal cancer. If the polyps and tumors are detected early, you will be able to remove them fairly easily. If the polyps are too large, or rectal cancer has spread too far into the colon or other parts of the body, you will have to choose a different method of treatment. There are minimal risks with transanal resection, and the benefits are great. Having yearly colonoscopies and sigmoidoscopies is important. Holding off on these test can change the method of treatment available for you.
