It is used to diagnose colonic polyps, colorectal cancer and inflammatory bowel disease to name a few examples.\n\nColorectal cancer screening has been shown to decrease colorectal cancer. Despite this the uptake by the general population is suboptimal.\n\nA new prototype colonoscope from Olympus with an additional distal bending section was designed. The investigators hypothesize that its performance characteristics will be similar to a standard colonoscope with patient tolerability.\n\nThis randomised control trial aims to invite patients attending their first outpatient colonoscopy and who are able to provide informed consent.(so they have had no prior experience) to assess the completion rate, patient and endoscopist satisfaction.\n\nPatients with prior colorectal surgery or previous colonoscopy were excluded.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* First outpatient colonoscopy\n* Able to provide informed consent\n\nExclusion Criteria:\n\n* Unable to provide consent\n* Prior colon surgery (except appendectomy)'}, 'identificationModule': {'nctId': 'NCT01142167', 'briefTitle': 'A Comparison of an Ultra-thin and Standard Colonoscope in Achieving Caecal Intubation', 'organization': {'class': 'OTHER', 'fullName': 'Chinese University of Hong Kong'}, 'officialTitle': 'A Study to Assess the Success Rate of Ultra-thin Colonoscopy Versus Conventional Colonoscopy for the First or Rescue Colonoscopy for Unsuccessful Procedures (UTC Study).', 'orgStudyIdInfo': {'id': 'UTC Study'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'Standard Colonoscopy', 'description': 'Colonoscopy with standard instrument', 'interventionNames': ['Procedure: Standard Colonoscopy']}, {'type': 'EXPERIMENTAL', 'label': 'Ultra-thin colonoscopy', 'description': 'New prototype scope', 'interventionNames': ['Procedure: Ultra-thin colonoscopy']}], 'interventions': [{'name': 'Standard Colonoscopy', 'type': 'PROCEDURE', 'description': 'Standard colonoscopy will be used during colonoscopy', 'armGroupLabels': ['Standard Colonoscopy']}, {'name': 'Ultra-thin colonoscopy', 'type': 'PROCEDURE', 'description': 'Ultra-thin colonoscope will be used during colonoscopy', 'armGroupLabels': ['Ultra-thin colonoscopy']}]}, 'contactsLocationsModule': {'locations': [{'city': 'Hong Kong', 'state': 'Hong Kong', 'country': 'China', 'facility': 'Endoscopy Center, Prince of Wales Hospital', 'geoPoint': {'lat': 22.27832, 'lon': 114.17469}}], 'overallOfficials': [{'name': 'James Y Lau', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Chinese University of Hong Kong'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Chinese University of Hong Kong', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Professor', 'investigatorFullName': 'James Yun-wong Lau', 'investigatorAffiliation': 'Chinese University of Hong Kong'}}}}
