Bronchoscopic management of bronchopleural fistula.

In recent years successful bronchoscopic management of bronchopleural fistulas (BPFs) by locating its site and then blocking the leaking segment with any of the several agents available has gained recognition. It is now considered as an alternate mode of management of BPF. Here we present a case of non-resolving pneumothorax that was managed successfully using bronchoscopic glue (cyanoacrylate glue) instillation.

Tratamento endoscópico de fístulas da árvore traqueobrônquica com dispositivos para a correção de defeitos do septo interatrial: resultados preliminares / Endoscopic treatment of tracheobronchial tree fistulas using atrial septal defect occluders: preliminary results

As fístulas da árvore traqueobrônquica, sejam elas broncopleurais ou traqueoesofágicas, apresentam etiologia multifatorial, com incidência variável na literatura. Em geral, apresentam alta morbidade e mortalidade, com indicação formal de correção cirúrgica. Entretanto, a condição clínica dos pacientes muitas vezes não permite uma reintervenção cirúrgica de grande porte. Além disso, as tentativas de fechamento endoscópico raramente têm sucesso, principalmente em fístulas de grande diâmetro. Relatamos os casos de três pacientes submetidos ao fechamento endoscópico de fístulas, sendo duas maiores que 10 mm, com a aplicação de dispositivos oclusores utilizados na cardiologia intervencionista, de forma minimamente invasiva e com resultados iniciais positivos. Esses dados sinalizam que essa pode ser uma técnica promissora na resolução de fístulas da árvore traqueobrônquica.

Fistulas in the tracheobronchial tree (bronchopleural and tracheoesophageal fistulas) have a multifactorial etiology and present a variable incidence in the literature. In general, the related morbidity and mortality are high. Once such a fistula has been diagnosed, surgical closure is formally indicated. However, the clinical status of affected patients is usually unfavorable, which precludes the use of additional, extensive surgical interventions. In addition, attempts at endoscopic closure of these fistulas have seldom been successful, especially when the fistula is large in diameter. We report the cases of three patients submitted to endoscopic closure of fistulas, two of which were larger than 10 mm in diameter, by means of the insertion of atrial septal defect occluders. The procedure was minimally invasive, and the initial results were positive. The results indicate that this is a promising technique for the resolution of tracheobronchial tree fistulas.
