PURPOSE: There are many articles about the role of barium esophagography for the diagnosis of gastroesophageal reflux disease. However, there are only rare articles reporting on laryngopharyngeal reflux disease. The purpose of this study is to evaluate the usefulness of performing esophagography with the water-siphon test as an initial screening test for patients with suspected laryngopharyngeal reflux. MATERIALS AND METHODS: From October 2002 to December 2004, barium esophagography with the water-siphon test was performed for 707 patients who had the typical symptoms and telescopic findings of laryngopharyngeal reflux. The results of the 707 esophagograms (the group with laryngopharyngeal reflux) were compared with those of 122 patients who were confirmed as having gastroesophageal reflux upon performing pH-metry (the group with gastroesophageal reflux) and the 324 patients without laryngopharyngeal reflux symptoms (the control group). The results of the water-siphon test were classified into normal, mild, moderate and severe degrees of gastroesophageal reflux. RESULTS: On the water-siphon test for the laryngopharyneal reflux group patients, 71 patients had normal (10.0%), 207 had mild (29.2%), 201 had moderate (28.4%) and 228 had severe (32.2%) degrees of reflux. The positive rates of the water-siphon test were 90.0%, 89.3% and 54.6% for the groups with laryngopharyngeal reflux, gastroesophageal reflux and the control group, respectively. A statistically significant difference was observed between the group with laryngopharyngeal reflux and the control group, and between the group with gastroesophageal reflux and the control group, respectively (p>0.05). CONCLUSION: Esophagography with the water-siphon test is useful as an initial screening test for laryngopharyngeal reflux disease.

BACKGROUND/AIMS: Laryngopharyngeal reflux (LPR) is an extraesophageal manifestation of gastroesophageal reflux disease. Endoscopic assessment of LPR is needed for convenient diagnosis and documentation of treatment efficacy. The aim of this study was to investigate the interrater reliability of LPR among endoscopists based on endoscopic laryngeal images. MATERIALS AND METHODS: Nineteen endoscopists participated in this study. Before the test, they completed an intensive education program by an otorhinolaryngologist on the reflux finding score (RFS), which is a validated laryngoscopic assessment of LPR. A total of 100 endoscopic laryngeal images were used for 3 tests of RFS. Cohen's and Fleiss' kappa coefficients were used to determine the degree of interrater agreement in the diagnosis of LPR. RESULTS: In the first test, the mean of Cohen's kappa coefficients for LPR diagnosis between the otorhinolaryngologist and each of the 19 endoscopists was 0.3. In the second test, after additional education, the mean kappa value was 0.32. Fleiss' kappa coefficients for diagnosis of LPR among the 19 endoscopists in the first and second tests were 0.30 and 0.26, respectively. CONCLUSIONS: A short-term education program for endoscopists did not result in an improvement of accuracy in the diagnosis of LPR. Further studies using advanced educational programs for endoscopists are required.

BACKGROUND AND OBJECTIVES: A 24-hour ambulatory dual probe for pH monitoring is the most specific and sensitive test for laryngopharyngeal reflux (LPR) disease. However, the use of this probe is not well tolerated in some patients due to discomfort and the invasive nature of the procedure. Thus, the diagnosis of LPR is usually made according to symptomatic responses to empirical treatment using a proton-pump inhibitor for patients with high score of reflux symptom index (RSI) and reflux finding score (RFS). The aim of this study is to evaluate the relationship between the RSI and RFS and pH monitoring using a 24-hour ambulatory dual probe, and determine the role of RSI and RFS in the diagnosis of LPR. SUBJECTS AND METHOD: We studied 100 patients who underwent pH monitoring using a 24-hour dual probe because of laryngopharyngeal reflux related symptoms or laryngoscopic findings. The various parameters of the 24-hour dual probe pH monitoring were compared with the scores of RSI and RFS. RESULTS: In 24-hour dual probe pH monitoring, 64 of 100 patients tested positive for LPR. The mean of RSI score was significantly higher in the positive LPR group than in the negative group. However, RFS did not differ between the two groups. RSI scores were significantly associated with the reflux number in the upright position of the 24-hour dual probe pH monitoring. There was no correlation between RFS and the parameters of the 24-hour dual probe pH monitoring. CONCLUSION: RSI can be a reliable diagnostic tool for laryngopharyngeal reflux disease instead of the 24-hour ambulatory dual probe pH monitoring.
