Congenital bronchoesophageal fistula associated with esophageal diverticulum in the adult

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.

Esophageal diverticulum serves as a unique cause of bronchoesophageal fistula in children: A case report

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.

[Congenital esophagobronchial fistula in an adult. Case report]

Congenital esophagobronchial fistulae are uncommon anomalies generally discovered during the neonatal period due to overt symptoms. Rarely symptoms are discrete, leading to discovery in adulthood; exceptionally the patients are totally symptom free or present minimal signs such as coughing at ingestion of fluids. Less than 200 adult cases have been reported in the literature. We report a new case of this type II congenital esophagobronchial fistula. A 59-year-old woman was hospitalized for exploration of cough at ingestion of fluids. The radiographic work-up reveal dilatation of the left bronchial tree and suspected esophagobronchial fistula. An esophago-gastro-duodenal barium study demonstrated a fistula between the mid esophagus and the left posterobasal bronchus. Fistulectomy and left lower lobectomy were performed. Outcome was favorable. The diagnosis of adult esophagobronchial fistula should be entertained in patients with an uneventful history who present localized bronchial dilatation associated with cough induced by fluid ingestion.
