Association of heartburn and laryngopharyngeal symptoms with endoscopic reflux esophagitis, smoking, and drinking

Abstract

Objectives: This study was conducted to investigate the association of laryngopharyngeal symptoms and heartburn with endoscopic esophagitis, smoking, and drinking. The clinical importance of the Reflux Symptom Index (RSI) in predicting endoscopic esophagitis was also evaluated.

Study design: Case series with planned data collection.

Subjects and methods: From November 2006 to February 2007, 156 adults received a whole-body physical check-up. They filled out the RSI questionnaire and were dichotomized into either a "no problem group" or a "possible patients group" according to their scores on the RSI. All subjects received an esophagoscopy. The relationship between RSI score and endoscopic esophagitis, smoking, and drinking was analyzed.

Results: Voice change, but not heartburn, was significantly associated with endoscopic reflux esophagitis. Based on the RSI scores, some items in addition to voice change were significantly associated with smoking or drinking but not with endoscopic esophagitis.

Conclusions: While screening patients for reflux esophagitis by using the RSI questionnaire, there is little value in using heartburn to predict endoscopic esophagitis in Taiwanese people. On the other hand, a husky voice might be a good clinical indicator of patients at risk of having reflux esophagitis.
