Eosinophilic Esophagitis: Analysis of Food Impaction and Perforation in 251 Adolescent and Adult Patients

Abstract

Eosinophilic esophagitis is a rapidly emerging, chronic inflammatory disorder. Prolonged inflammation evokes structural alterations and a fragile esophageal wall prone to perforation/rupture and food impaction. This report assesses the risk of spontaneously arising and procedure-induced complications and proposes practical recommendations. The Swiss Esophageal Esophagitis Database documented 251 confirmed cases. A chart review identified which patients had required endoscopic bolus removal and/or experienced transmural esophageal perforation/rupture. In addition, a MEDLINE search for "eosinophilic esophagitis" with "esophageal perforation" or "esophageal rupture" was undertaken. During an 18-year period, 87 patients (34.7%) experienced 134 food impactions requiring flexible (124, 92.5%) or rigid (10, 7.5%) endoscopic bolus removal. Transmural perforation occurred in 20% (2/10) of rigid procedures, and 1 esophageal rupture (Boerhaave's syndrome) was observed. Bolus removal by rigid endoscopy is a high-risk procedure and should be avoided in eosinophilic esophagitis patients who require a gentler approach. Whether food impaction and esophageal wall remodeling can be prevented with anti-inflammatory medication is still undetermined. All Boerhaave's syndrome cases should be evaluated for underlying eosinophilic esophagitis.
