Abstract
Inflammation in eosinophilic esophagitis (EoE) often leads to esophageal strictures. Evaluating esophageal narrowing is clinically challenging. We evaluated esophageal distensibility as related to disease activity, fibrosis, and dysphagia. Adult patients with and without EoE underwent endoscopy and distensibility measurements. Histology, distensibility, and symptoms were analyzed. EoE subjects had significantly lower distensibilities than controls. We found a cohort with esophageal diameter under 15mm despite lack of dysphagia. This study raises concern that current assessments of fibrostenosis are suboptimal. We describe a cohort with unrecognized slender esophagus that were identified via impedance planimetry measurements. This tool provides additional information beyond symptomatic, histologic and endoscopic assessments.
