Combined treatment with beaded EWS, Gore-tex patch and N-butyl-2-cyanoacrylate for bronchial fistula: The novel "sandwich method".

An 84-year-old man underwent right basal segmentectomy for primary lung cancer and developed empyema accompanied by a bronchopleural fistula (BPF). Emergency open-window thoracotomy was performed. Although the general and nutritional conditions improved, the fistula did not close naturally, and we planned to close it 6 months after surgery. In this report, we describe, for the first time, a novel method for closing BPF using an endobronchial Watanabe spigot (EWS), polyglycolic acid (PGA) sheet and N-butyl-2-cyanoacrylate (NBCA). We named this method the"sandwich method."
