Limited Diagnostic Value of Laryngopharyngeal Lesions in Patients With Gastroesophageal Reflux During Routine Upper Gastrointestinal Endoscopy

Le résumé fourni par la source

BACKGROUND AND AIMS: There is growing evidence that gastroesophageal reflux disease (GERD) may cause typical laryngeal/pharyngeal lesions secondary to tissue irritation. The prevalence of those lesions in GERD patients is not well established. The aim of this study was to evaluate the prevalence of GERD signs in the laryngopharyngeal area during routine upper gastrointestinal endoscopy. METHODS: Between July 2000 and July 2001, 1,209 patients underwent 1,311 upper gastrointestinal endoscopies and were enrolled in this study. The structured examination of the laryngopharyngeal area during upper gastrointestinal endoscopy was videotaped for review by three gastroenterologists and one otorhinolaryngologist, blinded to the endoscopic esophageal findings. From the 1,209 patients enrolled in this prospective study, all patients (group I, N = 132) with typical endoscopical esophageal findings of GERD (Savary-Miller I-IV) were selected. The sex- and age-matched control group II (N = 132) underwent upper gastrointestinal endoscopy for different reasons, had no reflux symptoms, and had normal esophagoscopy. RESULTS: In the two groups of patients, we found no difference in the prevalence of abnormal interarytenoid bar findings (32%vs 32%), arytenoid medial wall erythema (47%vs 43%), posterior commissure changes (36%vs 34%), or posterior cricoid wall edema (1%vs 3%). The only difference was noted in the posterior pharyngeal wall cobblestoning (66%vs 50%, P= 0.004). CONCLUSION: The results of this large systematic investigation challenge the diagnostic specificity of laryngopharyngeal findings attributed to gastroesophageal reflux.
