Laryngopharyngeal Symptoms and Esophageal Disorder: The Role of Heterotopic Gastric Mucosa in Upper Esophagus

alexandrossfakianakis shared this article with you from Inoreader Laryngopharyngeal Symptoms and Esophageal Disorder: The Role of Heterotopic Gastric Mucosa in Upper Esophagus via Clinical Otolaryngology Abstract Background Heterotopic gastric mucosa in the upper esophagus (HGMUE) was considered as geneogenous manifestation. However, its clinical characteristics may beyond to our knowledge if we focus on its extra-esophageal presentation. So the aim of this study was to investigate the relationship between HGMUE and laryngopharyngeal symptoms. Method Eight hundred and eleven patients who had gastric endoscopy examination were enrolled in this study and the cervical esophagus was examined for the patch during withdrawal of the endoscope. Questionnaire for gastroesophageal reflux disease (GERD-Q) and Reflux Symptom Index (RSI) were completed by all the patients. Pathology feature and therapeutic effect of HGMUE patients were evaluated. Result About 34.53% of the patients undergoing the gastroduodenoscopy had laryngopharyngeal (LP) symptoms. The relevance rate of HGMUE in LP(+)group(10.69%) was higher than that in LP(-) group(2%). The LP symptoms were related to the histological type and expression of H+-K+-ATPase in the histological sample of HGMUE patients. The positive rate of H+-K+-ATPase was 100% in LP(+) group, and that in LP(-) group was 28.6%. PPI therapy was effective for improving the LP symptoms in HGMUE patients. The RSI score in LP(+) patients decreased from 8.12±1.46 at baseline to 4±0.74 at the end of 8 weeks after treatment of PPI. Conclusion HGMUE was an important cause of LP symptoms in patients, especially in those who had no evidence of GERD. The mechanism of HGMUE induced LP symptoms was due to its location and the function of acid secretion according to the endoscopic finding and histologic characteristics. View on Web
