Portobiliary fistula: successful transcatheter treatment with embolisation coils

Although portobiliary fistula is a recognised complication of percutaneous transhepatic biliary drainage, it is extremely uncommon and can result in haemobilia. Herein, we present a case of complicated transhepatic biliary drainage catheter insertion in a patient with underlying hepatitis B liver cirrhosis, which resulted in a portobiliary fistula. The patient had a preoperative transhepatic biliary drainage procedure done prior to a Whipple's operation for a large, obstructive, gastrointestinal stromal tumour of the duodenum. To the best of our knowledge, this is the first case in the English medical literature reporting the successful treatment of portobiliary fistula by embolisation of its tract with embolisation coils, without compromising the portal vein or bile ducts.
