|A: As a general rule, a physician would not perform an elective colonoscopy procedure on a pregnant patient. The risks of the examination, therefore, depend upon the relative risks and benefits of the diagnoses under consideration. If a limited endoscopic examination were required during pregnancy, it could possibly be limited to a flexible sigmoidoscopy ( partial colonoscopy) which can be done without conscious sedation (thereby avoiding the risk of drugs given for sedation). Patients who have conditions such as ulcerative colitis should schedule surveillance examinations before attempting to become pregnant so that every attempt can be made to achieve clinical remission prior to pregnancy. The patient who is in remission before pregnancy is more likely to remain symptom free during pregnancy than the person beginning pregnant with active disease.
