Fig. 20From: Imaging assessment after pancreaticoduodenectomy: reconstruction techniques—normal findings and complicationsBiliary vs pancreatic fistula. Two different patients (a) 65-year-old male patient during abdominal pain three weeks after pancreaticoduodenectomy due to adenocarcinoma. (b) 50-year-old male patient with fever 21 days after pancreaticoduodenectomy due to ampulloma. Both patients presented fluid collection near the surgical bed, the both were homogeneous and no enhancement was present (big arrows). Fluid drainage analysis confirmed biliary fistula in a and pancreatic fistula in b. Note the similar imaging appearance, being indistinguishable one fistula from each otherBack to article page
