Early Increase in Blood Supply in Patients With Barrett's Esophagus (EIBS in BE)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01188980
Recruitment Status : Completed
First Posted : August 26, 2010
Last Update Posted : April 22, 2016

Herbert C. Wolfsen, Mayo Clinic

Brief Summary:
The purpose of this study is to determine if early Barrett's specialized intestinal metaplasia can be detected by measuring early increased blood supply of the esophageal tissue, with 4 Dimensional Elastic Light-Scattering Fingerprinting, (4D-ELF) technology in real time.

Condition or disease
Barrett's Esophagus

Study Type : Observational
Actual Enrollment : 90 participants
Observational Model: Case-Only
Time Perspective: Prospective
Official Title: Detectable Esophageal Early Increase in Blood Supply (EIBS) in Patients With Barrett's Esophagus
Study Start Date : June 2010
Actual Primary Completion Date : April 2013
Actual Study Completion Date : April 2013

NoBE (control)
BE without dysplasia
BE with dysplasia

Primary Outcome Measures :
  1. determine if early increase blood supply (EIBS)can predict presence of Dysplasia [ Time Frame: 10 minutes during standard upper endoscopy ]
    To determine if early increase blood supply (EIBS), as measured in Barrett's glandular mucosa segment, can predict the presence of Dysplasia in patients with known diagnosis of Barrett's esophagus (BE).

Secondary Outcome Measures :
  1. determine if EIBS can predict presence of BE in patients undergoing upper endoscopy [ Time Frame: 10 minutes ]
    EIBS measurements taken from buccal mucosa and esophagus will be compared in patients without BE, patients with BE without dysplasia, and patients with BE dysplasia. EIBS measurements will be obtained from normal squamous mucosa in the mouth, proximal esophagus, areas of BE in the distal esophagus, and measurements from the gastric cardia/hiatal hernia (at least 4 cm below the Z line.
