  Purpose

The purpose of this project is to develop an accurate method to identify patients that suffer from acid reflux, but may not present with classic reflux symptoms (such as heart burn). Additionally, it is the purpose of this project to utilize the Unsedated Small-caliber Endoscopy (USE) to assess the prevalence of Barrett's esophagus in a population of patients with laryngopharyngeal reflux (LPR) symptoms and to define normal patterns of LPR. Laryngopharyngeal reflux (LPR) is when a small amount of stomach contents and acid are pushed up through the esophagus and may affect the vocal cords and upper respiratory tract.

It is suspected that patients with LPR symptoms may have a prevalence of Barrett's esophagus similar to that found in a population with typical reflux symptoms. We propose to systematically test this hypothesis using the USE.

This project is designed to improve the methods of identifying patients with a form of acid reflux that is often undetected, and thus untreated. If this project is successful then more patients with Barrett's esophagus will be identified; furthermore, screening and treatment for this pre-cancerous condition will be improved.


Condition Intervention Phase
Extra Esophageal Symptoms: Cough Throat Clearing Hoarseness Difficulty Swallowing Drug: Proton Pump Inhibitor Phase 2

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Screening for Barrett's Esophagus in Otolaryngology Patients

Further study details as provided by National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK):

Primary Outcome Measures:
  • The primary aim of the study is to establish that patients with symptoms of LPR who are referred to an otolaryngology clinic have a prevalence of Barrett's metaplasia equivalent to that of a population with GERD symptoms. [ Time Frame: One time ]

Estimated Enrollment: 500
Study Start Date: May 2004
Estimated Study Completion Date: November 2012
Estimated Primary Completion Date: November 2012 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Proton Pump Inhibitor
    Screened patients with extraesophageal reflux symptoms will be followed prospectively in order to gauge response to acid suppressing medication treatment. Non-responders will be tested with pharyngeal pH monitoring.
