Background
Endoscopic ultrasonography (EUS) and high-resolution manometry (HRM) can be used in the evaluation of eosinophilic esophagitis (EoE) for frequent symptoms such as dysphagia. However, the role of these examinations is not clear.
Aims
The aim of this study was to objectively evaluate the subjective symptoms of EoE patients with EUS and HRM.
Methods
Patients who had endoscopic findings indicative of EoE and matched the number of eosinophil infiltrates used as diagnostic criteria were recruited between September 2018 and August 2019. Evaluable subjects underwent EUS and HRM and completed the Gastrointestinal Symptom Rating Scale (GSRS) questionnaire. The esophageal wall thickness (evaluated with EUS) and HRM parameters between patients with and without symptoms were retrospectively compared. Symptomatic patients were re-examined using EUS and HRM 6 months after treatment.
Results
A total of 35 patients (29 males, median age of 49 years) were divided into symptomatic (20 patients) and asymptomatic groups (15 patients). The esophageal wall was thicker, and the distal contractile integral (DCI) values were higher in the symptomatic group (P < 0.001). In addition, DCI values were positively correlated with esophageal wall thickness. After treatment, the GSRS scores showed an improving trend for each item. Esophageal wall thickness and DCI values were significantly decreased (Ps < 0.001).
Conclusions
Esophageal wall thickening and increased esophageal body pressure may be involved in subjective symptoms. In addition, treatment may reduce esophageal thickness and pressure along with improvement of subjective symptoms.
