![]() ![]() You will not feel anything during a biopsy or polyp removal. If polyps are found, they can be removed with a special wire loop on the scope. If any abnormal regions are noted, a biopsy may be performed using a special tool on the colonoscope.If you are awake, you may feel some cramping or bloating during this time. To get a clearer view, air will be pumped through the colonoscope to open up the intestinal passage. When you are adequately sedated, the doctor will insert the colonoscope into your rectum and begin advancing the instrument upward through your colon.Though many people sleep through the procedure, you may awaken at times. This type of anesthesia is called " twilight sleep" and is different than general anesthesia. Sedative and pain medications will then be given, either in pill form or through your IV. Once in the procedure room, you will be asked to lay on your left side with your knees bent.After you change into a hospital gown, a nurse will take your vitals and place an IV line in your arm or hand.Medication side effects: An adverse reaction (e.g., nausea or vomiting) or rarely, an allergy, to the pain or sedative medications used during a colonoscopy may occur.Symptoms include fever and abdominal pain. ![]() Postpolypectomy syndrome: This syndrome occurs in roughly 1 in 1,000 colonoscopies and is most likely to occur when electrocoagulation (cautery or burning) is used to stop bleeding at the base of a polyp when it's being removed.Factors that increase a person's risk for this include increased age, being hospitalized (in intensive care) at the time of the procedure, a history of abdominal pain, and Crohn's disease. It can also occur if an instrument punctures the bowel. Colon perforation: Perforation of the colon (a hole in the colon) is rare, but may occur when air is injected into the colon during the procedure to improve visualization.Infection: Infections are rare after a colonoscopy.Bleeding: Bleeding occurs in roughly 1 of 1,000 colonoscopies and is more likely to occur when a polyp is removed. ![]()
