This study will test the use of a new device called a segmental stiffening wire (SSW) in colonoscopy to correct a problem called looping. Colonoscopy is the best test for detecting early colon cancer and removing growths called polyps, which can become colon cancer. Sometimes the flexible tube (colonoscope) used in the procedure loops at a certain point as it advances through the colon, making it difficult to move further and causing the patient pain from excessive stretching of the colon. The SSW is designed to prevent this by stiffening the part of the tube that would otherwise form the loop. Healthy subjects between 50 and 80 years of age and healthy subjects 40 years and older who have a family history of colon cancer may be eligible for this study. Participants undergo colonoscopy a day after self-administering a bowel cleansing preparation. The first part of the procedure is done similarly to that of a flexible sigmoidoscopy, and no sedation or pain medication is used. The colonoscope is inserted into the rectum and advanced about one-third the length of the colon. Pain or discomfort should be mild to moderate cramping and a feeling of having to move the bowels. The subject is asked to score his or her pain level at this point using a standard pain scale. If there is pain, the procedure is stopped and an x-ray is taken to determine if the colonoscope has looped. If it has, the loop is undone and the SSW is used. Another x-ray is then taken to document that the loop has been prevented with the SSW, and the procedure is completed as per standard medical practice. Subjects are taken to the recovery area, informed of the test results and then discharged home in the care of an accompanying adult.
Colonoscopy for investigation of lower gastrointestinal complaints or for colon cancer screening is one of the more frequent procedures performed by the Divisions of General Surgery and Gastroenterology. Traditionally, this has been performed while under conscious sedation (medication induced) which may improve patient acceptance and tolerance of the procedure but adds to the operative risk of the procedure. The investigators propose a randomized prospective blinded trial to assess the utility of adding pleasing olfactory stimulation to the inhaled oxygen during the conscious sedation for colonoscopy in an effort to reduce the total doses of sedatives required while maintaining a similar level of sedation. This may decrease the overall period of recovery for the patient, increase the number of procedures which may be accomplished, and decrease the potential complications related to conscious sedation.
