Polyps are abnormal tissue inside the colon in the form of a mole or wart. Most of them are risk factors for colon cancer and this is why they must be removed.
90% of polyps are less than 10 mm in size and have no symptoms. This is why colonoscopy is so important as prevention because it is the best way to find them. Larger polyps can cause bleeding, pain in the abdomen, change in stool consistency, or even no symptoms. The larger the size, the greater the risk of cancer and it is a priority to remove them.
For prevention to be effective, I must completely remove the polyp because if any residual tissue remains, it can regrow. One or two millimeter polyps can be removed with the biopsy forceps. Those between 3 and 10 mm and some of the largest diameter can be completely removed using a device called a polypectomy loop, which is like a loop that traps the abnormal tissue and tears it off. Today, this procedure is done without applying current, what we call a cold procedure to reduce the risk of the colon wall breaking. There are polyps that due to their shape or larger size require other devices such as needles to inject into their base, metal clips, among others. The polyps that we call pediculated, that is to say that they seem to be the stem of a tree, require the application of current for their resection.
