Impaired esophageal motor function in eosinophilic esophagitis

Area of Science:

• Gastroenterology
• Immunology
• Allergy

Background:

• Eosinophilic esophagitis (EoE) is a chronic immunoallergic inflammatory esophageal disease.
• It is a significant cause of digestive morbidity in pediatric and young adult populations.
• Symptoms like dysphagia and food impaction in adults may indicate underlying esophageal motor disorders and impaired distensibility.

Purpose of the Study:

• To review current scientific evidence on esophageal motor disorders in patients with eosinophilic esophagitis.
• To focus on findings from high-resolution manometry, ambulatory manometry, and impedance planimetry.

Main Methods:

• Literature review of studies investigating esophageal motility in EoE.
• Analysis of data from high-resolution manometry, ambulatory manometry, and impedance planimetry.

Main Results:

• Esophageal motor abnormalities and impaired distensibility are frequently observed in EoE.
• Various manometric and impedance techniques have provided insights into these motility dysfunctions.

Conclusions:

• Esophageal motor disorders are a key feature of eosinophilic esophagitis, contributing to symptoms.
• Further research using advanced manometry and impedance techniques is crucial for understanding EoE pathophysiology.
