Esophageal motor abnormalities are common in patients with eosinophilic esophagitis (EoE) and may contribute to symptoms. Eosinophils influence esophageal motility, and some motility abnormalities can be improved after medical treatment.
Background: Eosinophilic esophagitis (EoE) is a chronic disorder of the esophagus characterized by an eosinophil-predominant inflammation and symptoms of esophageal dysfunction. Eosinophils can influence esophageal motility, leading to dysphagia worsening. The spectrum of esophageal motility in EoE is uncertain. Aim: We performed a systematic review to investigate esophageal motility in EoE. Methods: MEDLINE, EMBASE and EMBASE Classic were searched from inception to 16th November 2021. Studies reporting esophageal motility findings in EoE patients by means of conventional, prolonged, and/or high-resolution esophageal manometry were eligible. Results: Studies on esophageal conventional and high-resolution manometry (HRM) found that all types of manometric motor patterns can be found in patients with EoE and investigations on 24-hour prolonged manometry demonstrated an association between symptoms and intermittent dysmotility events, which can be missed during standard manometric analysis. Panesophageal pressurizations are the most common HRM finding and may help in formulating a clinical suspicion. Some motility abnormalities may reverse after medical treatment, while other major motility disorders like achalasia require invasive management for symptoms control. HRM metrics have demonstrated to correlate with inflammatory and fibrostenotic endoscopic features of EoE. Conclusion: Esophageal motor abnormalities are common in patients with EoE and may contribute to symptoms. The resolution of dysmotility after medical treatment corroborates that eosinophils influence esophageal motility. (c) 2022 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd.
