Screening for varices with a video endoscopy is limited by its cost, patient compliance, and the risks of sedating a patient with portal hypertension. Capsule endoscopy is a novel method that may reduce the costs and increase compliance for screening.\n\nThe investigators propose to screen 100 consecutive patients with advanced cirrhosis for esophageal varices. A capsule endoscopy and video endoscopy will be done on the same day. The varices seen on video endoscopy will be graded using a standard grading scale. Both capsule and video endoscopy images will be assessed in a blinded fashion by 4 independent investigators. Finally, the video endoscopic images will be compared to capsule endoscopy to develop a capsule endoscopy grading system that corresponds to video endoscopy.\n\nThe primary endpoint of the study will be to develop a grading system for esophageal varices using capsule endoscopy. Secondary endpoints of the study include sensitivity, specificity, inter- and intraobserver variation of variceal grading using capsule endoscopy; patient acceptance as assessed on a visual analogue scale; and a cost comparison (facility fees + professional fees) of the two screening methods.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Advanced cirrhosis with portal hypertension based on imaging, clinical suspicion, or liver biopsy\n* Age greater than or equal to 18 years old\n* Able to give consent\n\nExclusion Criteria:\n\n* Current implantable cardioverter-defibrillators or pacemaker in place\n* Suspected intestinal obstruction\n* Esophageal swallowing disorder\n* Esophageal stenosis\n* Age less than 18 years old\n* Pregnancy\n* Known Zenker's diverticulum\n* Patients with previous endoscopic or surgical esophageal treatment"}, 'identificationModule': {'nctId': 'NCT00475592', 'briefTitle': 'Validation of Esophageal Variceal Grading: A Comparative Study of Upper Gastrointestinal (GI) Endoscopy and Capsule Endoscopy', 'organization': {'class': 'OTHER', 'fullName': 'Johns Hopkins University'}, 'officialTitle': 'Validation of Esophageal Variceal Grading: A Comparative Study of Upper Gastrointestinal (GI) Endoscopy and Capsule Endoscopy', 'orgStudyIdInfo': {'id': 'VaricealGrading_EsoCapsule'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Capsule Endoscopy', 'interventionNames': ['Device: Esophageal Capsule Endoscopy']}, {'type': 'ACTIVE_COMPARATOR', 'label': 'Upper Gastrointestinal Endoscopy', 'interventionNames': ['Device: Upper Gastrointestinal Endoscopy']}], 'interventions': [{'name': 'Esophageal Capsule Endoscopy', 'type': 'DEVICE', 'armGroupLabels': ['Capsule Endoscopy']}, {'name': 'Upper Gastrointestinal Endoscopy', 'type': 'DEVICE', 'armGroupLabels': ['Upper Gastrointestinal Endoscopy']}]}, 'contactsLocationsModule': {'locations': [{'zip': '21205', 'city': 'Baltimore', 'state': 'Maryland', 'country': 'United States', 'facility': 'Johns Hopkins Hospital', 'geoPoint': {'lat': 39.29038, 'lon': -76.61219}}], 'overallOfficials': [{'name': 'Paul J Thuluvath, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Johns Hopkins University'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Johns Hopkins University', 'class': 'OTHER'}, 'collaborators': [{'name': 'Ethicon, Inc.', 'class': 'INDUSTRY'}], 'responsibleParty': {'type': 'SPONSOR'}}}}
