Screening for Barrett's Esophagus in Otolaryngology Patients
This trial is active, not recruiting.
|Conditions||extra esophageal symptoms:, cough, throat clearing, hoarseness, difficulty swallowing|
|Treatment||proton pump inhibitor|
|Sponsor||National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK)|
|Start date||May 2004|
|End date||November 2012|
|Trial size||500 participants|
|Trial identifier||NCT00695227, DK066165-02, K23 DK66165 (completed)|
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.
|Endpoint classification||efficacy study|
|Intervention model||single group assignment|
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.
