First Reported Case of Bronchoperitoneal Fistula From Bladder Cancer Metastasis Treated With the Novel Utilisation of an Endobronchial Valve

Bronchoperitoneal (BP) fistulas are exceedingly rare and complicated conditions. Given the rarity of this diagnosis, with reports limited to case reports or case series, there is limited literature regarding treatment, which ranges from conservative to surgical management. A search for 'bronchoperitoneal fistula from bladder cancer' on PubMed and Google Scholar revealed no reported studies. Therefore, to our knowledge, this is the first case of BP fistula caused by metastatic bladder cancer. Moreover, to our knowledge, we present the second instance in the literature of utilizing an endobronchial valve to treat a BP fistula. Ultimately, the procedure was successful and allowed for improved quality of life.
