Eosinophilic Esophagitis for the Otolaryngologist

[摘要] Objectives. This paper focuses on current diagnostic and treatment options for Eosinophilic Esophagitis (EE).Study Design. literature review.Results. EE can be suspected on history and endoscopy although definitive diagnosis is strictly based on histopathology. It is a relatively new entity and is often misdiagnosed as gastroesophageal reflux (GERD). Eosinophilic infiltration of the esophageal mucosa is responsible for esophageal symptoms which can range from mild to debilitating dysphagia and food impaction, when untreated. In fact recurrent foreign body and food impaction can often be blamed for undiagnosed EE. There seems to be a strong familial component and association with allergy. The introduction of transnasal esophagoscopy in adult laryngology has enabled otolaryngologists to readily diagnose EE and promoted awareness of this often difficult to recognize entity.Conclusions. Despite higher awareness, the literature suggests that EE remains a commonly misdiagnosed condition especially in the otolaryngology community. Genetic studies are required to unfold the true familial and genetic component of this fascinating entity.
