"Acetic Acid Chromoendoscopy in Barrett's Esophagus Surveillance

Status Terminated

Clinical Trial Summary

Neoplasia in Barrett's esophagus could be missed during routine random biopsies. We propose a study using chromoendoscopy with Acetic Acid to increase the yield of biopsies in detecting neoplasia.

Clinical Trial Description

Neoplasia in Barrett's esophagus is often focal and can be missed by nontargeted biopsies alone. In recent years, various advanced endoscopic techniques have been utilized, but with varying success rates. Narrow-band imaging, trimodal imaging, spectral imaging and i-scan are technologies that are manufacturer dependent with limited varying success rates and have financial implications. At our institution, narrow band imaging is routinely utilized as a diagnostic tool for detecting Barrett's esophagus. Acetic acid is a commonly available dye that has been used in the detection of neoplasia in Barrett's esophagus. This study is aimed to prove the effectiveness of acetic acid chromoendoscopy in our Barrett's esophagus surveillance population. The goal is to compare the neoplasia yield of acetic acid chromoendoscopy with that of standardized random biopsy protocol. The sensitivity and specificity for neoplasia detection by these two methods will also be analyzed. Investigators plan to conduct this prospective randomized study for a period of one and a half years (beginning August 1, 2015, ending February 29, 2016). Based on data from 2014, we anticipate to enroll approximately 185 patients. All gastroenterologists (with privileges at Doctors Hospital at Renaissance) will participate in this study. Patients will be randomized to either acetic acid chromoendoscopy or current standard of care (standardized random biopsy protocol utilizing narrow band imaging). Random biopsies from both protocols and targeted biopsies (if identified) will be obtained and submitted to pathology department. These will be reviewed independently by two pathologists. Any discordant results will be reviewed by an outside expert pathologist. Statistical data analysis will be performed utilizing Datadesk XL software. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
