A colon polypectomy is surgery to remove polyps from the colon (large intestine). A polyp is a mass of tissue. Some polyps can turn into cancer or cause other problems.
Most polyps can be removed during a colonoscopy or sigmoidoscopy.

Colon polyps are usually removed to prevent colon cancer.
Rarely, larger polyps can cause rectal bleeding, belly pain, and bowel problems. A polyp removal will ease these symptoms.
Problems are rare, but all procedures have some risk. The doctor will go over some problems that could happen, such as:
Things that may raise the risk of problems are:
The surgical team may meet with you to talk about:
The doctor will give a sedative. You will feel relaxed.
A long, flexible tube called a scope will be used. The doctor will pass the scope into the rectum and then the colon. The scope will pass air into the colon. It will create more space for the doctor. A camera on the scope will send images to a monitor in the room. The doctor will be able to see the walls of the colon as the scope moves through.
The doctor will look for polyps. A wire snap will be passed along the scope. It will snip of the polyp and seal the area. Polyps may be destroyed with an electric current. The electric current is also used to close the wound and stop bleeding. Any removed tissue will be sent for lab testing. When the doctor is finished, the scope will be slowly removed.
For large polyps, a laparoscopic surgery may be needed. In this procedure, tiny tools will be inserted through small cuts in the belly and the colon. The tools will be used to find and remove the polyp.
30 to 60 minutes
There may be some cramping or lower belly pain during the procedure. Medicine will help ease discomfort. Some will sleep through the procedure. Gas pains and cramping are common after. These pains should go away with the passing of gas.
It will take an hour or so to recover from the sedative.
For 3 to 4 days after surgery, there may be a small amount of bleeding from the rectum.
Tea, coffee, cola drinks, alcohol, and spicy foods should be avoided for a few days. They can irritate the digestive system.
