Eosinophilic esophagitis is a relatively recently discovered disease of increasing incidence and prevalence and is a common cause of dysphagia and food bolus impaction. The definition of eosinophilic esophagitis continues to evolve, most recently with the characterization of proton pump inhibitor-responsive esophageal eosinophilia. The number of high-quality prospective, controlled trials guiding therapeutic decisions in eosinophilic esophagitis has increased steadily over the past several years. Treatment options at present focus on dietary therapy, particularly implementation of a 6-food elimination diet, and medical therapy, primarily the use of swallowed, topical corticosteroids. Proton pump inhibitors play an important role in current management. Conservative esophageal dilation is effective at ameliorating dysphagia in symptomatic patients with esophageal strictures. We conducted an evidence-based review of the diagnosis and treatment options in adults with eosinophilic esophagitis. The understanding of eosinophilic esophagitis continues to be refined. Continued validation of appropriate endpoints, however, is essential to establish the efficacy of existing and novel therapeutic approaches. [ABSTRACT FROM AUTHOR]

Abstract: Objective: To systematically evaluate the diagnosis of eosinophilic esophagitis (EE). Methods: A retrospective review of 657 patients seen at the EE center of a tertiary care children''s hospital between 1994 and 2007 was performed. Charts were reviewed for the 144 patients who were also seen by the otolaryngology service. Results: One hundred forty-four patients received 193 otolaryngology-related diagnoses. Eustachian tube dysfunction (27.5%) and sleep disordered breathing (24.9%) were the most common, followed by dysphagia (13.0%), rhinosinusitis/nasal congestion (9.3%) and airway stenosis (5.2%). Seventy-nine patients (54.9%) had a pre-existing diagnosis of EE at the time of their otolaryngology consultation. Twenty-one patients (14.6%) were referred to the gastroenterology service for evaluation for EE. Forty-four patients (30.5%) remained undiagnosed. Twenty-five of these patients presented with dysphagia, 16 of whom were not previously diagnosed with EE; only 4 of these 16 patients were referred for evaluation for EE. In one case, a child with moderate sized tonsils underwent adenotonsillectomy for dysphagia and failure to thrive; this patient was diagnosed with EE 1 month post-operatively. Conclusions: Twenty percent of patients with EE may require care by an otolaryngologist for a myriad of complaints. Even experienced pediatric otolaryngologists may not recognize this condition. Otolaryngologists should consider EE in patients presenting with dysphagia. A careful gastroenterology review of symptoms may also allow otolaryngologists to identify EE in patients with allergy mediated nasal complaints, or laryngeal/airway disorders.
