Abstract
INTRODUCTION: 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. METHODS: Adult patients with and without EoE underwent endoscopy and distensibility measurements. Histology, distensibility, and symptoms were analyzed. RESULTS: Patients with EoE had significantly lower distensibilities than controls. We found a cohort with esophageal diameter under 15 mm despite lack of dysphagia. DISCUSSION: This study raises concern that current assessments of fibrostenosis are suboptimal. We describe a cohort with unrecognized slender esophagus that were identified through impedance planimetry measurements. This tool provides additional information beyond symptomatic, histologic, and endoscopic assessments.
