This should disappear quickly with the passage of gas. You may feel some cramping or bloating because of the air introduced into the colon during the examination. Larger polyps are removed by a technique called snare polypectomy, in which a wire loop is passed through the colonoscope and the polyps are cut from the intestinal wall by means of a small electrical current.Īfter the test, you will be monitored in the recovery room until most of the effects of the medication have worn off. Tiny polyps may be completely destroyed by biopsy.
Removal of colon polyps is an important means of preventing colon cancer as the majority of cancers develop from polyps. Therefore, polyps are removed and analyzed microscopically. The majority of polyps are benign, but it can be difficult to discern whether a polyp is benign or cancerous by its outer appearance alone. Polyps are abnormal growths from the lining of the colon which vary in size from a tiny dot to several inches. What are polyps and how are they removed? These risks include bleeding, a tear in the intestine (perforation), risk of anesthesia and failure to detect a polyp. Colonoscopy is a very safe procedure with complications occurring in less than 1% of patients. Removing polyps is an important step is the prevention of cancer. With colonoscopy, it is now possible to detect and remove most polyps without abdominal surgery. Colonoscopy is the most accurate way to inspect the colon to detect polyps or early cancer. Following the colonoscopy, there may be slight discomfort which quickly improves with the expelling of gas. Colonoscopy is usually well tolerated with minimal discomfort. The doctor gives you intravenous sedation to help you relax and tolerate any discomfort during the procedure. There is often a feeling of pressure, bloating, or cramping at times during the procedure, which is related to the air that is put in the colon during the exam. The procedure usually takes about 20 minutes to perform. Your physician will remove polyps or take biopsies as necessary. As the colonoscope is withdrawn, the lining is carefully examined. While you are in a comfortable position on your side or on your back, the colonoscope is inserted into the rectum and advanced to the portion of the colon where the small intestine joins the colon. Since you will receive intravenous sedation for the procedure, please have a family member or a friend meet you at the hospital after your test to assist you in returning home. You will receive instructions from your doctor's office regarding the time your test is scheduled and what time you should arrive at the hospital. Colonoscopy is generally conducted on an outpatient basis in our endoscopy suite. This is done one to two days before the exam with an oral solution prescribed by your physician. The colon must be completely clean for the procedure to be accurate and complete. In the average risk patient with a normal colonoscopy, the test is repeated every 5-10 years. The frequency of colonoscopy is determined based on your risk factors and whether or not you have polyps on your colonoscopy. If you have any risk factors for colon cancer such as Crohn's disease, ulcerative colitis or a family history of colon cancer, your screening should begin at age 40 or at least 10 years before the age your relative was when diagnosed. Your physician may also recommend a colonoscopy exam if you have change in bowel habit, bleeding, or other symptoms indicating a possible problem in the colon or rectum. In patients with no gastrointestinal problems and no risk factors for colon cancer, the American Cancer Society recommends a first screening colonoscopy at age 45. It is used to diagnose colon and rectum problems and to perform biopsies and remove colon polyps. While the patient is under mild sedation or monitored anesthesia if deeper sedation is preferred, the physician inserts a flexible fiberoptic instrument called a colonoscope into the rectum and advances it through the colon (large bowel).
