Non-Operative Management of Bronchobiliary Fistula Due to Proximal Migration of Biliary Stent in a Patient With Unresectable Klatskin Tumor

Abstract

One of the methods for the biliary tree decompression in the case of Klatskin tumor is transpapillary stenting, which could be completed by stent migration in 4% to 10% of cases. Approximately half of the stent migrations are in the proximal direction. In this study, we reported a rare case of proximal trans-diaphragmatic stent migration to the lower lobe of the right lung with the formation of a biliarybronchial fistula (BBF).
