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.”
