Biliary fistula, Biliary-enteric fistula, Gall stone"/>
Biliary-enteric fistula is a rare disease, and the common causes of biliary-enteric fistula are gallstone, peptic ulcer, malignancy and trauma. It is known that the most common type of biliary-enteric fistula is the cholecysto- duodenal fistula, yet the combination of choledocho- duodeno-colonic fistula is a rare finding. A 78-year-old woman was admitted because she had suffered with right upper quadrant pain, a febrile sense and chills for 2 days. We confirmed the choledocho-duodeno-colonic fistula by performing gastroduodenoscopy, abdominal CT and an upper GI series. So, we report here on an usual case of choledocho-duodeno-colonic fistula, along with a review of the relevant literatures. (Korean J Gastrointest Endosc 2007;34:278281)
