Rationale:Most of the esophageal diverticulums are congenital traction instead of in childhood. In most conditions, esophageal diverticulums are free of any symptoms. As one of the rare entity, esophageal diverticulum can also result in bronchoesophageal fistula.Patient concerns:A 10-year-old girl was admitted due to a 2-month history of cough and choking after drinking, and fever for 3 days. No symptoms when taking solid food were found.Diagnoses:By esophagogram, 3-dimensional computed tomography and esophagoscopy, an esophageal diverticulum was demonstrated in the middle esophagus with a bronchoesophageal fistula visualized. Then the diagnoses of esophageal diverticulum and bronchoesophageal fistula were established.Interventions:A regular trans-anterolateral thoracotomy was carried out under general anesthesia with patient lying on the right side. The diverticulum was then removed and the fistulous tract was closed.Outcomes:The girl discharged on the 14th postoperative day and received a regular monthly follow-up, at present, no recurrence was found.Lessons:Bronchoesophageal fistula may be a complication of esophageal diverticula, and should be considered in cases of unexplained cough or recurrent pneumonia.
