Chronic aspiration bronchiolitis in a patient with esophageal diverticulum and gastroesophageal reﬂux disease

Purpose of the study: to present a description of the clinical observation of chronic aspiration bronchiolitis in a patient with a large diverticulum of the upper esophagus and gastroesophageal reﬂ ux disease (GERD).Materials and methods: a brief review of the literature on the modern concept of extraesophageal respiratory manifestations of GERD, the features of the course of upper esophageal diverticula, clinical and radiological symptoms of chronic aspiration bronchiolitis is presented. In the above clinical case, chronic aspiration bronchiolitis was a manifestation of gastroesophageal pathology.Results: The development of ﬁ brosing interstitial lung disease in a patient with a large upper esophageal diverticulum and GERD is presented.Conclusion: the problems of diﬀerential diagnosis of respiratory symptoms in esophageal pathology are shown. The authors hope that the described observation will increase the attention of doctors regarding comorbid ﬁ brosing interstitial lung diseases in esophageal pathology; the need for timely detection of a progressive ﬁ brotic phenotype and determination of indications for antiﬁ brotic therapy.
