Bronchoesophageal fistula secondary to esophageal diverticulum in an adult: a case report and literature review

Esophageal diverticulum with secondary bronchoesophageal fistula is a rare clinical entity that manifests as respiratory infections, coughing during eating or drinking, hemoptysis, and sometimes fatal complications. In the present study, we describe a case of bronchoesophageal fistula emanating from esophageal diverticulum in a 45-year-old man who presented with bronchiectasis. We summarize the characteristics of this rare condition based on a review of the relevant literature.
