A Case of Duodenobiliary Fistula Caused by a Metal Stent in a Patient with Hepatocellular Carcinoma

Biliary drainage can improve the quality of life in a patient with obstructive jaundice caused by malignancy. Biliary metal stent insertion is a very useful method because it drains the bile physiologically and patients have little discomfort with the procedure. It has a few complications such as restenosis, liver perforation, bowel perforation, fistula formation and stent dislocation. Perforation and fistula formation are caused by pressure due to the self expanding characteristics of the metal stent. We report here on a case of duodenobiliary fistula that was caused by a biliary metal stent in a patient suffering with hepatocellula carcinoma, and we also include a review of the relevant literature.
